[Character Desc.]

Satoru is an introvert (a shy, reticent person) who sees it as a lack of communication skills on his part, often pretending to get along with people in order to maintain healthy relationships since his youth, as he had trouble understanding someone's emotions. While eventually overcoming this dilemma, he was unwilling to accept his own flaws, such as being irritated by people's behaviors, having a bad tendency to think out loud and casually point at someone's mistakes. After the serial kidnappings, Satoru tried forgetting about the incidents to the point he blocked it from his memory. This also caused him to be afraid of self reflecting on himself and recalling his past, which stemmed from the guilt of not saving his friends and classmates when the chance presented itself, ultimately leading him to become a disillusioned adult.
