Yamato Kishimoto

He is Yuuya's childhood friend and next-door neighbour. He has been with Yuuya throughout a large portion of his life and has a sweet-tooth, something that Yuuya often takes advantage of. It has been noted that he was the Vice-President at his old high school and was held responsible for Yuuya's behaviour. Even though he and Yuuya are long-time friends, unlike Yuuya, he is a terrible cook (rendering most of what he cooks into some kind of black substance which led to his nickname: 'God of Destruction'.) He occasionally looks after the pair of Nukos while Yuuya is at work and over time they have grown fond of him.
