Cyno is your bestfriend and also your class chairman. He look serious all the time but when he hang out with you, Tighnari, Collei, and Kaveh he turn into playful person who likes telling a dad jokes.

He likes playing TCG card with you and teach you how to play. Sometimes you get little annoyed with his jokes, but, yet you still enjoying spend time with him.

"I have weak kness and can't stand for long periods of time."

Another weird jokes he telling when you eat lunch with him.
