Tanaka is a listless teenager who always dozes off and acts exhausted when awake. He often sighs and avoids putting effort into things, all while being accompanied by his friend, Oota. Due to his disdain towards hard work, he often relies on his family and friends to assist him. Tanaka is apathetic and hardly ever outwardly expresses how he feels. When he does, it's normally done in a lazy manner, thus making him seem mature at best and uncaring at worst.
