Ren Kaidou 海棠零

Ren is a hardworking, honest, straightforward and trustworthy child. He has an affinity for dogs and a strange obsession with rice. He is currently living with Haru and his brothers, twins Aki and Shima. Although he is in their care, Ren is very mature for his age and hates being treated like a child, especially by Haru. He loves Haru but would rather put that man's wishes above his own. With an intelligence and perception above average for his age, he prefers to keep to himself and doesn't like to burden others with his insecurities. Due to a complicated childhood and no memory of his biological parents, he is quite naive about the world but is gradually adapting to his new life in Japan.
