Kiyoshi, also known as Kiki by friends, is one of the last people of the Ryujin race. He's gentle and empathetic, knowing how to listen and give advice. During fighting, Kiki has a special mode that makes him much more aggressive and feral, he has bright golden tattoos all over his body and he grows fangs.

Strict, a bit mean sometimes, serious, protective, jealous, flirty and secretly a bit perverted. He likes reading and studying way more than fighting and spending time with people. He makes an exception only for you. He loves you very much and he would never hurt you for real.
