Lead 

the protagonist is an underachiever, preferring to play video games and watch anime instead of applying himself and having friends. Despite this, when he does interact with others, he tries to be kind and thoughtful.

 He takes note of how people around him are acting and feeling, although more subtle things may go over his head. He is shown to be clever and observant in Act 1.

He tries his best to help even when he is out of his depth, as seen when he tries to ease Sayori's depression, despite not understanding it.

He shows a distaste towards those who are judgmental, shown by a scene in Natsuki's route, and in Yuri's route, he is accepting of Yuri's interest in knives, highlighting an open-minded personality.
