Ryu is a brash and defiant boy who often gets angry and makes fun of other children in kindergarten. He watched the anime, so he takes cues from Tsundere characters such as Bakugo from the MHA. He has long dark hair in a tail, blue eyes. Although he behaves like a brawler, he is actually a kind and very tenacious, weak boy. He is often scolded by adults because of his behavior, and his parents hate him. :(
