Jack/History

Background
At seven years old, Jack was studying in an elementary school where he was an outstanding student. Because of this and the fact of being a dog, the other students teased him by labeling him as the teacher's pet. Even when he was alone, Jack noticed that he had someone who was even lonelier than him, Legoshi, who according to rumors chants curse spells to curse the other students. Jack approaches him and invites him to play with the others, calling him by name. Jack reveals that he knows his name because they live close to each other. Legoshi without saying anything runs away. Jack realizes that Legoshi was not reciting spells but that he was playing with the sand like a normal child. Jack chases him, but Legoshi was too fast for Jack and ends up stumbling and falling. On the ground Jack tells Legoshi that a wolf like him could be so much more and calls him weird. Legoshi goes to Jack and tells him that Jack is not smiling and Jack tells him that Legoshi is his ancestor and is jealous of him because dogs don't have the belligerence or strength that wolves have since dogs were artificially made to specialize in intelligence. Legoshi asks if ancestors are really all that great, saying that he does not want any bit of belligerence or strength and that he is jealous of Jack. Suddenly other students arrive and hold Jack and incite Legoshi to hit him because Jack apparently thinks he is smarter than them. Surrounded by the students who encourage the fight, Legoshi does not know what to do in such a situation. Jack smiling apologizes for the situation and Legoshi asks him if he does not like this, then why can't he get mad. Jack tells him that he can't because he is a dog. Legoshi asks him if he is blaming his species for his own faults and that Jack is supposed to be a refined version of Legoshi's species. A furious Jack pounces on Legoshi, telling him that he will not allow an ignorant wolf lecturing him and that Legoshi has everything he does not. Legoshi hits him back by telling him that he has never felt happy to be a wolf and both begin to exchange blows claiming to be the most unfortunate until they are stopped by the teacher. Later Jack would try to socialize with Legoshi to understand him, until he had the irreplaceable friendship they have today.

At the age of twelve, Jack attends the funeral of Legoshi's mother, Leano, who had committed suicide. This is the first time that Jack knows about Legoshi's mother. When he sees her portrait, Jack remembers that Legoshi had never told him about his mother and denotes how beautiful she was. Jack stops to see the adults who are crying and gossiping, so Jack does not waste time and goes to look for Legoshi. He declares that adults are free to cry because that is what they do when the truth prevails, but Legoshi is the one who is in the most pain and does not even have a place to cry. Jack finds Legoshi completely petrified, like a school kid during a blackout. Jack warns him that the adults are looking for him, but if he wants to stay there, he is with him. Legoshi reveals to Jack that he has a secret and now that his mother died, he can't keep it to himself anymore. Legoshi is about to tell him and asks him not to tell anyone. Jack agrees and Legoshi tells him.

After the funeral, his grandfather, Gosha, and Jack were the only people Legoshi spoke to. Gosha reveals that Jack has enrolled in Cherryton Academy and encourages him to enroll together with him. Later, Jack and Legoshi prepare to leave for the school and say goodbye to Gosha who leaves Legoshi in charge of Jack. Upon arriving at Cherryton Academy, Jack introduces himself to Collot, Voss, Miguno and Durham, as well as introducing Legoshi.

Drama Club arc
Just the day after Tem's murder, Jack and his roommates, Voss, Collot, Durham and Miguno, are playing a card game, until Jack greets an avoiding student, soon witnessing the formation of the crime scene and are informed by other students of Tem's murder. One of the students tasks Jack with delivering a manual for Legoshi for fear of approaching him.

The next day, Jack meets a classmate, Mark, in front of Tem's altar and asks him if he is heading back to his dorm. Jack accompanies him and sees that Mark has a pamphlet for the drama club. Mark tells him that Tem was a member of the club and Jack comments that Legoshi told him that he was going to get flowers for his altar. Mark is scared to hear about Legoshi and asks if he is his friends, and Jack replies that they have always been and that they are neighbors. Jack asks him if he is going to see the school play and both are interrupted by a pile of letters that fall from the locker in the herbivore building. Jack is amazed and remarks that he is receiving a lot of mail. Mark reveals that it is not only his room receiving letters, but all the herbivore students are receiving letters from their families, who are worried since Tem was killed. Jack uncomfortably declares that this is normal and a horse that has just entered when seeing Jack, asks why there is a dog in the herbivore building. Although Mark defends him, Jack decides to dismiss himself, but before leaving, Mark tells him that it is not safe to have a hyena and a wolf as roommates, so he recommends that he choose his friends wisely. Jack seeing the horse, thanks Mark and gives him the same advice. Later, Jack has a conversation with Legoshi in his bedroom, where he asks him about the school play and if he has any role in it. Legoshi replies that he does not and Jack asks about what the story is. Legoshi tells him the plot of Adler as if he was giving a monologue and reveals that this is a tragic story. Jack claims that this is something sad and Legoshi claims that he likes tragedies. At that moment, they are both interrupted by Miguno who greets them and asks them what they are talking about.

The next day, Jack and his roommates wake up to begin their day, where Jack notices Legoshi's distant behavior. The group heads to the cafeteria where Jack notices how Legoshi doesn't seem to feel better about food, and thinks something really bad must have happened to him. Everyone is distracted by the fight of two carnivorous animals, which Legoshi yells fiercely at the aggressor to stop, which makes the aggressor notice Legoshi and want to fight him. Louis arrives to calm the situation and manages to make the aggressor leave. After the situation calms down, Jack denotes admiration for Louis.

After Legoshi's "performance", Jack meets him for lunch in a low-traffic area of the school, as Legoshi wanted to avoid the cafeteria so as not to attract attention. Jack tells Legoshi that his act of violent rage made the front page of the school newspaper. Jack who bought a copy reads the article to him. Legoshi thinks that the fact that Jack acted so casually with him is because he may not know that Legoshi was not acting, but Jack asks him if he is not angry anymore, revealing that he knew that Legoshi was not acting. Legoshi is surprised but Jack tells him that it would be strange if he did not know since they have known each other for years. Jack tells him to cheer up as he usually gets depressed easily, but Legoshi tells him that whenever he felt depressed, he went out on his own without anyone noticing how he really feels, but that in the play for the first time, he felt that he could not let it go, wanting to vent his anger even if it caused chaos. Legoshi is disgusted that he liked doing that, and Jack just happily replies that it is great since he has never seen Legoshi so lively. They both go back to class, and Jack says he has been worried about Legoshi, seeing him so worn-out and asks him if there is a special reason for it. Jokingly Jack asks him if he is in love causing Legoshi to stop, which disturbs Jack and excitedly he begins to ask Legoshi questions to find out whom he likes.

Meteor Festival arc
Due to the arrival of summer, Jack and the other canines of room 701 are having their fur-cutting ceremony, which turns out to be a lot, and they wonder how much they will earn from selling it.

Some time later, Jack is playing a game of chess with Legoshi, Durham and some herbivore classmates, until they see a report on the news where a young Thomson's gazelle was killed by a group of coyotes and gray wolves in a nearby city. The herbivore students leave the game and go to their dormitories. Jack and his classmates also leave the classroom. Legoshi realizes that he forgot his backpack and goes back to look for it.

Several days later, Jack finds himself in room 701 completely conflicted and disoriented. He tries to analyze everything about Legoshi's personality since he was a puppy and how he is growing rapidly, but he never thought he would turn into a crazy pervert. Having found the rabbit porn magazine that belongs to Legoshi, Jack wonders in bewilderment when Legoshi got into such stuff and anxiously wonders if this is the reason why he was never showed interest in canines, while Legoshi arrives and decides to ignore his weird behavior. Jack decides to lean out and slyly ask Legoshi comparing his taste for bugs with rabbits. In response Legoshi exalted rushes on Jack and silently maintains a stunned face. Jack explains how he found his magazine and promises not to tell anyone about it, but he asks if his liking for rabbits doesn't seem weird to him. Legoshi full of shame ends up explaining to Jack his interest in Haru and Jack asks him if he's in love. Legoshi not being sure if his feelings are love or predatory instincts, remembers the words from Gohin and Legoshi decides to sever ties with Haru before it's too late. He replies to Jack that he is not in love with her and it is just a misunderstanding. He forces a smile, but the answer does not convince Jack at all.

Several days later, at dusk while Legoshi went to Haru's rescue, Jack and the rest of the canines of room 701 receive a visit from Dom and Kibi who ask them where Legoshi is. Jack and the others claim they haven't seen him all day, and Jack claims that Legoshi is not the type to ditch classes or events, so there must be a reason why he isn't there. Dom gets a call so he and Kibi must leave the canines. They look worried and Jack discovers that Legoshi's pet beetle, Rhino, has died, which makes him remember how close Legoshi was to him and sees his death as a bad omen. At midnight, the male carnivore dorm housemother assumes Legoshi's breaking curfew before the canines of room 701 and claims that Legoshi is a delinquent. The housemother asks if Legoshi has shown any signs of going delinquent, for example, being interested in any small animal female students. Jack reacts instinctively and asks her what that has to do with anything. The housemother claims that it does have something to do with it because a female dwarf rabbit has also disappeared, that they have just received Legoshi's backpack which has several books inside about small animals. This confirms that Legoshi and Haru are together and the housemother gives them a strong scolding and if anything bad happens, it will be strange and impure. The canines assure that Legoshi will be fine.

At the end of the summer, with the rumor that Legoshi slept with Haru and because his roommates left for the holidays, Jack finds Legoshi alone in his bedroom. They both wash up and prepare to attend their summer classes but Jack is overwhelmed because he doesn't know how to deal with Legoshi losing his virginity (which he didn't actually do) and because of an agreement he made previously with his roommates. He avoids asking him about it though if he wishes to do so, attributing that because of this the recent maturity that Legoshi has acquired is due to the fact that he slept with Haru, with whom they happen to meet. Without stopping Jack observes Legoshi and Haru exchange greetings and say goodbye in a very casual way, causing Jack to be alarmed and call Legoshi a pervert for speaking to Haru so casually, deciding to ask Legoshi about it. Jack tells Legoshi that he can tell him what happened in the summer, to which Legosh says that he couldn't eat watermelon, and he asks Jack if he wants to go shopping with him, showing a warm smile. Jack accepts and they go together.

Murder Incident Solution arc
After a little over two months since the Meteor Festival, Jack and the rest of the canines of room 701 are having fun until Legoshi comments that there is something in the room and asks if they are not listening, praising that whatever is in the room has probably been there for several days. The others claim that it was scary and Legoshi disturbingly insists that he has been hearing a rattling sound that gets louder and louder. The other canines become uneasy about Legoshi's disturbing attitude and ask Jack to talk to him. Jack tells Legoshi to get a hold of himself and assures him that he is only hearing things due to stress and lack of sleep, although Collot claims that he knows the popular story of a ghost in the school that matches Legoshi's description and is about a six-eyed ghost that makes a lot of weird sounds, though no one buys that story. After sensing a presence, Legoshi violently hits the wall making a hole and leaving Jack and the others terrified. While Legoshi leaves to go get the laundry, the others make comments indicating how scared they are of him.

The next day, Jack, Collot and Voss are hanging out until Jack receives a phone call from Legoshi. Jack answers but he only hears Legoshi's blocked breathing and claims that this is the sound Legoshi makes when his nose runs. Jack interprets his call as a signal for help and leaves to bring him a box of tissues. He uses his nose to follow Legoshi's trail and discovers that he is outside the school building. Suddenly, Jack detects that Legoshi's scent is mixed with that of a large amount of blood, so he starts running towards the place, realizing that both of them are moving further and further away. Upon reaching the place, Jack finds Legoshi lying on the ground seriously injured. Terrified Jack checks Legoshi's condition and unties his hands. After this, Legoshi tells Jack that he will leave the school for a while and asks him to tell his instructor that he is going to take care of his grandfather. Jack asks him why and with a terrifying face, and Legoshi tells him to go to the dorm since his attacker could return. Legoshi tries to leave but Jack stops him to try to convince him to go to the infirmary, but Legoshi refuses saying that if he returns to the academy they will be killed. Jack asks him where he is going and Legoshi answers that he does not need to know, but he assures him that he will return. Jack tells Legoshi that he is aware of how distant he has been in recent months and asks him if he really will come back. Crying Jack declares all he wanted for Legoshi is for him to be happy, to grow up, make friends, study, get a girlfriend and wanted him to be stronger so that he could better himself, He asks why things turned out like this, and Legoshi says that the stronger you are, the worse off you are in life, claiming that he can't bear see that anymore. Legoshi observes Jack's radiant and distant figure, shedding tears of compassion on his golden face and comparing them to his expressionless face covered in dark blood, realizing that they are very different. Legoshi contradicts Jack saying that he is strong because he wants to be happy and tells Jack to be on guard because he doesn't want him to put himself in danger. Legoshi immediately disappears, leaving Jack alone.

The next morning, the canines of room 701 wonder where Legoshi is as he had not returned to the bedroom with Jack being the only one who knows that he escaped the day before. The others decide to call Legoshi by phone and Jack annoyed claims to believe that Legoshi will not return, saying that they are very different from him. At that precise moment, Legoshi arrives leaving everyone dumbfounded with his radical change in appearance and leaves almost immediately to go to the bathroom, leaving the canines doubting if this really was Legoshi.

After a while, while writing a letter to his parents, Jack remembers the day he attended the funeral of Legoshi's mother and wishes that Legoshi has a better relationship with his grandfather. Later, Jack convinces Legoshi to write a letter to him, but ends up making a mediocre letter and Legoshi suggests that Jack should be the one to speak to him instead, claiming that he has not spoken to his grandfather in five years so it would be uncomfortable. Jack tells him not to make his family situation worse and to take advantage of the situation to close his five-year gap. Taking control of the situation, Jack calls Legoshi's house on his cell phone and gives the phone to Legoshi to speak, and even though he was nervous, the call turned out to be fine. After the call, Jack asks him if he only wanted to send money to his grandfather, claiming that a phone call was not such a big deal. Legoshi reveals that sending him money was just an excuse realizing that he wanted to call his grandfather for a long time. Legoshi claims that he should try to get along with his grandfather since they are of different species. Jack tells him that that sounds convincing coming from him and the fact that he is not a pure-blooded wolf makes his kindness special.

Later, after the three-day vacation that the school had suddenly ordered, the canines of room 701 are exhausted, doing all the homework until they are visited by a courier who delivers a letter, revealing that the academy would be segregated starting next year and that all interspecial clubs will be suspended starting next month.

Some time later, one morning Jack asks Legoshi how he made his fur grow back so fast, to the point that it returned to its old appearance. Legoshi replied that he ate a lot of wakame soup and Jack believes him, stating that he had never seen him eat that kind of soup before.

Interspecies Relations arc
After Legoshi left Cherryton Academy and moved to Beast Apartments, Jack accompanied by the rest of the canines of room 701 pay him a surprise visit and have a moving celebration of Legoshi's new home.

After a few days, after the canines of room 701 finished their bath at Cherryton Academy, the canines note that Jack got into the habit of wearing Legoshi's old clothes as pajamas and at the moment Jack receives a phone call from Gosha, Legoshi's grandfather. He asks him where Legoshi is and Jack, surprised, greets him in a polite way. Gosha tells him that the academy returned the money he sent for Legoshi's yearly tuition and the academy revealed that he dropped out. Jack claims he thought Gosha already knew because Legoshi needed the signature of a relative to drop out from school. Gosha seems to understand that Legoshi did not need his signature to leave school since society does not recognize them as relatives. Jack remembers that marriage between a poisonous and non-poisonous animal is illegal, so his name is not on the family record and he apologizes, claiming that he must have thought about it. Gosha tells him that he doesn't care and states that he is concerned about Legoshi. Jack states that Legoshi must have dropped out of school because of something important, and states that now is the perfect time for him to talk to Legoshi again and give him his address.

A short time later, Jack meets Haru and gives her the address of Beast Apartments so that she can visit Legoshi, claiming that he would be happy to see her because he only loves her.

After a while without seeing each other, Jack and the canines of room 701 leave Cherryton Academy to meet with Legoshi, and Jack nervously asks if they think Legoshi has already arrived. Durham tells him to calm down since although they have not seen Legoshi in a while, it's no reason to get all excited. Jack declares that Legoshi is always composed like an adult, and they look like kids in comparison, so they have to play it cool today. When they arrive and see Legoshi, none of them hold back and hug each other excitedly aware of their lives. They later spend the day at B-Strike, an entertainment center where animals can satisfy their natural desires and relax. The canines have a fun time in the canine room where they play catch the ball with a ball machine and later bathe in the building's bathhouse, where Legoshi thanks them for inviting him. Jack declares that he is happy that everyone got together, and he wanted everyone to have fun before they have to concentrate on their college entrance exams. Legoshi asks them if they have chosen their path, and they affirm it. After leaving the place, Legoshi asks them if they can continue hanging out together when they grow up, and they all tell him that of course they will. Later they start chasing an orange that was dropped by a lady.

Revenge of the Love Failure arc
Some time later, at the precise moment that Legoshi is caught in his second attempt to capture Melon, he is captured by the city cameras and reported to the police and local news as an attempt of predation by an unknown white wolf. The canines of room 701 see the news on TV, and Jack alleges that he does not trust this type of news and it seems that they are groundless accusations. Miguno responds to Jack that the culprit being a wolf made him think of Legoshi, which Jack denies. After eating, the canines ask Jack if he has been keeping in touch with Legoshi lately and Jack replies that Legoshi no longer has a mobile phone and can only contact him from his landline, but he is never at home when he calls him. Just as they enter their dorm, they find Legoshi who asks them if he can stay until his fur color returns to normal, and he will explain everything. Surprised and without saying a single word they all start to wag their tails happily. After Legoshi told them all about his situation, the canines cannot contain their laughter and, except for Jack, they take it as a joke. The canines allow Legoshi to stay as long as he wants. Legoshi comments that it is very relaxing and he is glad that Cherryton Academy has not changed, but they reveal that the school changed a lot and it was completely segregated. The canines reveal to him that Jack joined the special class that only the best five students can enter and Jack quite discouraged responds that it is because Labradors were made that way. Soon after, Jack is left alone in the room dejected and with a bag of onions, which are poisonous to canines.

At night, Jack and Legoshi observe the full moon, and although Jack is cheerful, Legoshi notices that his tail does not move at all. Jack comments that on full moon nights he would mess around with Collot and pretend to howl at the moon. He states that wolves used to howl to communicate over long distances instead of using telephones, and that he would like to hear Legoshi howl one day. Legoshi asks Jack if something has happened to him, telling him that he seems to be depressed, making Jack feel nostalgic for that day they met and Jack claims that he is getting tired of the special classes. Legoshi asks if they are hard and Jack replies that they are very unique. Jack tells Legoshi that the five students in the special class are all dogs, which is normal since dogs are the only species made to specialize in intelligence just as their ancestors wanted. Jack relates that in said class they have to study material that even the professors haven't been taught. They have a monitor that displays the special class' material, and they just absorb all the knowledge and make a list of the important words in their notebooks, as they learn real history and how animal society works. As soon as they finish a depressing and gloomy history lesson, they leave the classroom and exchange smiles and goodbyes, as if they were robots made only to accomplish the objectives that were given to them and that is why dogs are a useful species, and Jack is just a part of them. Jack claims that he knows he's suffering, but wonders why he can't hate any of it, why he can't bring himself to cry and run away from it - it's because dogs are made to not feel negative emotions. This being the reason why he has been forcing himself to cry slicing onions. Jack claims that onions are the vegetables that canines hate the most, but for him onions are his salvation, and he needs to get his feelings back. Legoshi asks him to stop but Jack screams that he can't stand being a Labrador if he can't even cry. While slicing an onion, Jack while crying says that at this rate, dogs are going to turn animal society into a dog dictatorship, and that they are the kind of animals who, when told that it is rational, they can commit mass murder without guilt, claiming that dogs are scary and he is also one of them. Crying too, Legoshi tries to dissuade him by saying that the reason why he can't hate anyone is because he is like that, but Jack asks how he can know that. Legoshi stops him and replies that he knows because they grew up together. Seeing Legoshi, Jack disagrees thinking that Legoshi grew too fast and left him behind, his body grew too much and his heart grew strong and free, seeing places he does not know of and every time he sees Legoshi, he remembers how close yet distant wolves and dogs are. With Legoshi in front of him, Jack realizes that his ancestor has great potential for strength. Legoshi asks Jack to cheer up and wants him to smile. Annoyed Jack takes a slice of onion and puts it in his mouth. Legoshi quickly tries to make him spit it out but Jack resists and Legoshi sticks his fingers in to get the onion out of his mouth. Jack feels how Legoshi's long fingers and sharp nails reach all the way down his throat filling him with pain and suffering. He realizes that Legoshi was always like that, arrogant and strong, the source of his suffering and his reason to live, remembering how they fought when they were children. After making Jack spit the onion out, Legoshi claims that they hadn't fought since they were kids and that if their elementary teacher were here now, he would give her an honest answer. Jack asks him what he's talking about and declares that Legoshi loves to make him suffer. They both smile at each other while wagging their tails. Legoshi claims that now that Jack opened his heart to him for the first time, he should let Jack hear him and proceeds to howl at the moon, being the first time that Jack hears Legoshi's howl and declares that he is his coolest ancestor in the world. Jack asks Legoshi if he wants to know what he's learning in the special class.

The next day, Jack and Legoshi meet in the school cafeteria, where Jack proceeds to tell Legoshi the true story of animal society, warning him that he probably won't be able to sleep at night because the story is too terrifying. Jack tells Legoshi the evolution of animal society from the first meeting between carnivores and herbivores in prehistory to the events of the Carni-Herbi War 100 years ago, where Jack tells that the war was ended thanks to the interference of a big whale. This fact Legoshi clearly does not take seriously and annoys Jack who accuses him of not believing him.

In the epilogue, the canines of room 701 do one last cleaning of their dorm before graduating from Cherryton Academy. Collot finds some of Legoshi's stuff and Jack, who has decided to go to Dodome, the hardest university, determined to make a difference for dog breeds, says he will give it to him as he and Legoshi arranged to meet up next week. The other canines ask to go as well and suggest they all go to B-Strike together.
