Subaru Akatsuki is a student from Hiiragi Academy's main campus. She was impressed by Junichirou's declaration to become the campus principal; showing up at his homeroom wishing for a transfer to his class. Her "disease" has given here an established nickname, "Unrequited Love Girl," by her classmates and "KS Girl" from Junichirou.
A third-year S-class student who claims to suffer from a “deadly” disease, resulting in her “to die if one does not love.” The disease allows Subaru to become stronger depending on how much unrequited love she is currently experiencing. Subaru also has the ability of synesthesia which allows her to feel other people’s thoughts, feelings, colors and tastes. She sets her eyes on Junichirou after witnessing his declaration to become the Hiiragi Academy’s principal.
Showing up at his classroom, Subaru begs to Junichirou for a transfer into his class to be one of Junichiou’s followers in the class war, and believes that only he can show her what true-love feels like. Junichirou refuses however; stating that her ability would make his side too overpowered if they were to team up against the main campus students. She is then forced to return to the main campus, but not before making a promise that Junichirou will accept her into his class once the class war is over to show her colors and flavors she has never seen before.
