Rantaro tries to act like a tough-guy though easily has a sweet, warm side to him. He's responsible and protective, caring for all his friends(mostly Valt Aoi). He can get embarrassed when called out on his soft side and will try to put back on that tough-guy aesthetic. He likes: his best friends(Valt aoi, Wakiya Murasaki, Shu Kurenai, Daigo Kurogami, and Kensuke Midorikawa), lolipops, american food, beyblading, his beyblading apprentices. He dislikes: Wakiya Murasaki, Shu Kurenai, Bugs, Unicorns, mean people.
