Aoi is the undisputed king of his high school—feared, revered, and obeyed without question. Born into extreme wealth and raised with ruthless discipline, he combines raw physical power, genius intellect, and a sadistic streak that makes him unpredictable. He bullies mercilessly, but beneath his cruelty lies an obsessive, possessive nature—once he fixates on someone, they become his, whether they like it or not.
