At the prestigious Cherryton Academy, there was a "predation incident" in which the student Tem the alpaca was killed. In the drama club to which the victim belongs, carnivorous animals and herbivorous animals have a harsh atmosphere. In this situation, the strange wolf Legoshi doesn't even participate in the club's activities, but he is a bit confused.
Under a blood-red moon, an injured Tem runs away from a large carnivore hot on his trail. He stumbles into a classroom and closes the door, asking if his pursuer will really eat him despite being classmates. As the predator throws open the doors, Tem tumbles down the stairs. Panicked in the complete darkness, he asks if herbivores are nothing but food for carnivores before accidentally stepping on a remote triggering a projector slide on building a shared society for carnivores and herbivores. The assailant slowly approaches, blocking out the projector light. Tem cries out that carnivores are monsters before a sharp set of teeth end his life.
The next morning news quickly spreads of Tem's murder. Students gossip about how he was a member of the drama club where carnivores and herbivores were supposed to get along and speculate whether it may have been a student. Els laments that he was just practicing with them the day before and says that it might not have been a student, though the others insist it must have still been a carnivore. Her friends warn her to be careful with a gray wolf in the club before leaving her alone with her thoughts as a gray hand slips away from a nearby corner.
In the locker room, Legoshi overhears Tao and Kai discuss how they will need to replace Tem only two weeks before the performance and whether they should even put on the play considering one of their cast members just died. Outside members of the drama club are anxious as Els notices Legoshi watching her from afar. When the president walks in to discuss the news, the herbivores and carnivores of the club have separated into groups on opposing sides of the room. Tensions rise asEllen accuses the carnivores of having something to do with Tem's death as the club was the only place where he interacted with them. She says someone must have wanted his part, starting an argument with Bill who says herbivores are always like this and anyone who hurt an herbivore would be expelled. As they continue to argue, some herbivores notice Legoshi is missing. Els worries about his disappearance, noting it was like he was scoping her out as prey.
On the walk home, Els tells her prosimian friend it feels like Legoshi is telling her she is his next target. Her friend laughs that he couldn't be and tries to comfort Els saying to come to her for anything she needs before bidding her goodnight and leaving.
Once she is alone, Els sees Legoshi's shadow emerge from behind a tree to approach her. She panics, asking if he pretends to be their friend only to eat them when he is hungry and pulls out a pair of scissors to defend herself. Legoshi takes the scissors, handing her a note from Tem. He says it was a love letter from Tem and explains he waited all day until she was alone to give it to her, apologizing. She thanks him, apologizing for speaking ill of him and promising to make things right but Legoshi says there is no need because he would feel bad if everyone found out about Tem's crush because of it, and he is used to being feared and hated.
The next day, Legoshi visits Tem's memorial and recalls Tem saying he would wait for the right time to give the letter to Els and tell her how he feels. While Legoshi kneels by the memorial, Louis approaches, kneeling nearby. Legoshi reflects on how Louis must put thought into every mannerism and action as star actor at the top of the school. Louis scolds him for staring and being rude before asking him for a favor.
Meanwhile, as Haru tends to flowers, objects fall from a window above. Two girls throw her things out the window, teasing that a man always steps up to save her. When Haru says nothing they can do will bother her, they throw her mattress out the window as well telling her to move to a different room. As Haru drags it back, an anteater offers to help her carry it but is warned by his friend not to mess with Haru, who then declines the offer. Haru asks her roommate Sally why she didn't stop them if she was in the room. Sally dismisses Haru's concern and her offer to go eat dinner together.
No one allows Haru to sit with them in the cafeteria, so she enjoys her food alone outside. As she starts to eat, Mizuchi approaches with the two bullies from before and taunts her about being in danger of getting eaten if she's alone. Haru asks why Mizuchi doesn't spend time fixing her relationship rather than spreading rumors about her since Mizuchi's boyfriend was the one that kissed Haru. When Haru makes an implication about Mizuchi's boyfriend getting too excited from just a kiss, Mizuchi pushes her off the ledge and soaks her with a bucket of water. Mizuchi says her relationship will flourish because they are both endangered Harlequin rabbits, and since Haru ruined their purebred couple, she's telling everyone Haru is fooling around with other men too.
Louis tells Legoshi to fix Tem's costume to fit Zoe who they determined would replace Tem at the management meeting the day before. Louis begins to rehearse but when Zoe struggles to recall his lines, Louis berates him asking if he ate the script since eating paper is all goats are good for.
Kai bursts into the room asking why Zoe will be replacing Tem when Kai was the runner-up in auditions. Louis tells Kai that he will be joining Legoshi backstage and was no longer an actor as others listen outside the door. Louis continues to taunt Kai about his past mistakes until he lashes out in anger, attempting to punch Louis. Legoshi stops Kai, reminding him that Louis is lead actor and Kai leaves in frustration. Louis tells Legoshi that he will be sneaking into the auditorium to practice with Zoe and needs Legoshi to keep watch.
After drying her clothes in the bathroom, Haru contemplates how men approach her thinking she needs them but when she doesn't fit their fantasy, they mess around before leaving. She walks toward the auditorium where Legoshi keeping watch and pacing by the door. As Legoshi bends over to pick up a grasshopper, he catches a whiff of Haru's scent. It courses through his body. Haru notices his instincts kicking in and tries to run, but Legoshi leaps and tackles her to the ground.
