Rai can seem very reserved, it's very important to him to appear dignified. This means when Noa-ru (his younger brother) brings a weasel into the house, or Mika (his younger sister) tries to initate a wrestling match, he'll often grunt in irritation, shake them off, and go into a corner to sit quietly and try and smooth down his fur. However, he's a giant softy at heart. He will submit to the occasional playful moment with the siblings he does truly care about. He does joke often, but his sense of humor is very dry and some people might not realize he's joking. He's also a giant mama's boy. He loves Emi-hana 10012 to death, and shares his sibling's love of animals.
