Among the types of personas included in the game, he was a Teacher's Pet. If Ryusei saw a corpse or witnessed a murder, he would report to his teacher, unless another Teacher's Pet already has. He would give Ayano a suspicious look before crossing his arms if she aimed her phone at him. He could not participate in physical fights.
