Rokurou himself is kind and cheerful, taking care of the people around him. In this, he is a good match for the headstrong and reckless Velvet Crowe, as well as the initially blank and will-less Laphicet. He is jovial, supportive, and protective of the other members of the party, serving as a parental figure to Laphicet and Kamoana and a drinking buddy to Eizen, while passionately fighting alongside Velvet and keeping Eleanor Hume from being sucked into the Earthpulse. He frequently teases Magilou much like a brother would.
