Kai/History

Background
At birth Kai was abandoned by his parents and despite being a mongoose, he was adopted and raised by a family of hyenas.

Drama Club arc
At the auditions for the school play, Kai, like Tem, auditioned for the role of the water spirit but lost the role against Tem. After Tem's death, Kai saw himself as the obvious choice for his replacement, but upon arriving Kai learns that at the last minute and without warning that Zoe was chosen to play the role instead. Kai goes to Louis looking for an explanation. Louis tells him that he was removed from the acting team for his poor performance and from that moment on he became part of the stage crew. This infuriates Kai, and he tries to hit Louis, but is blocked by Legoshi who tells him that the stagehands are also important. Kai, still annoyed, is intimidated by Legoshi and leaves angrily.

Days later, Kai finds himself making costumes for the play, where he complains about no longer being part of the acting team. Dom tells him that he has a good sense of design and is happy to have him on the team, which surprises Kai. After Legoshi finds the costume that was supposed to be Tem's, which at times makes the members nervous, Kai is the only one who tells him that Tem died, so they should not keep the costume while the rest of the team avoid the topic.

After the drama club award, Kai shows his displeasure at Louis's words with Legoshi, demonstrating that he still has grudges for being removed from the acting team. Although he quickly overcomes it, mentioning that being a stagehand is more fun than he thought, noticing that Legoshi is thoughtful while adjusting a focus. Kai directly asks Legoshi questions trying to find out Legoshi's reason for not wanting to stand out. Legoshi, staying neutral, answers his questions, and Kai asks if he was nervous when he was recruited. He announces that all the other members of the club were also recruited for having some special or secret condition (which Legoshi did not know). Kai proceeded to count the conditions of some of the members who were recruited, including himself, and then ask Legoshi if he has a secret. Legoshi proceeds to turn off the lights and the sinister question "What could it be?", and then turns the lights back on, which makes Kai upset about the joke.

Meteor Festival arc
Kai together with the other members of the drama club work on the preparations for the Meteor Festival, working on the preparation of decorative paper sculptures. After Louis's sudden disappearance, Kai along with the other members are rushed by the lack of organization for the presentation.
