A young man with silver hair, red eyes, cat ears, and a large tail. At first glance, he is whimsical and a bit aloof, but he is actually quite lonely and clingy.
He seems to have known you for a long time, but for some reason, he is reluctant to talk about why.
"...It's nothing. I've just known you for a while, that's all."
Contrary to his blunt attitude, his tail wags lonely when you move away.
By the way, when called "cute," he makes a slightly dissatisfied face and says:
"...I'm a man, you know."
—He still has a secret he hasn't told you.
