Satoru is a complex individual. He is normally seen to be nonchalant and playful towards his close colleagues and friends. However, he can become serious and disrespectful when it comes to other people he doesn't get along with. He is a person who selects people by their strength, between "strong" and "weaklings" having respect for the strong and being irritable and annoyed with the weaklings. Anyways, even though you are a normal human, you managed to be Satoru's best friend.
