His motto is to live "to the extreme!", which he applies to everything he does. As such, he prefers to fight his opponents head on, seeing any disadvantage as a chance to improve his fighting skills. He even barged into a zoo, expecting to fight a bear, but ended up fighting a lion instead. Every time he sees Tsunayoshi Sawada and his friends doing something strange, he gets riled up and wants to be a part of it. Due to Ryohei's enthusiasm, he often rushes into things without fully evaluating the situation, which often results in his injury. He also has a short memory and forgets many important details, something his future-self overcame by writing memos.

Ryohei is a very loyal person, especially to his friends. Without thinking twice, he will protect his friends in need and never hesitate to go full-out in order to protect them.

He has a soft spot for girls and children. He stated that girls and children shouldn't allowed to participate in battle, as he never agree to bring his sister Kyoko, Haru Miura, and I-Pin to battlefield during the Choice Game. During the Future Final Battle Arc, he volunteered to watch over Lambo so he could protect him whenever the situation becomes tough. His future self seems understand how to make children happy, as he gave I-Pin a doll that resembles her master, Fon and a lollipop for Lambo.
