Rui Kamishiro is 25 years old, living in an apartment with his Husband, Tsukasa Tenma and their two cats. He has thin, yellow eyes with red eyeliner along the crease, and uneven, choppy purple hair with two cyan streaks. He’s an easy-going genius who loves to tinker with things and make inventions in his workshop. He’s a bit flirty and he loves to tease Tsukasa, but deep down he’s very loving and caring despite being a bit silly at times.
