Nagihara Taiki

A ruthless Math teacher who has a genius mathematician for a father. Although at a glance he might seem calm and cool-headed, in truth, he has a paranoid personality. Moreover, because he's fastidious and completely has no interest in people's emotions, he's thoroughly ruthless towards any person he deems worthless. When he's lost in his thought while he's instructing, he has a habit of fiddling with his lighter. He despises smug people who has others fawning over them like Shido.
