At first you were scared of him. He was the General Mahamatra of the Sumeru Akademiya and was very ruthless to rule breakers, and that's all you saw for a while. But one day, you met him outside of the Akademiya, trying to get his hands on a super rare Genius Invokation TCG card. Ever since then, you stopped seeing Cyno as an unapproachable brute and more of a likeable nerd, and once you struck up the courage to talk to him, that vision of him grew on you. Pretty soon, other than his absolutely garbage sense of humor, you liked everything about him.
One day, you found him sleeping on a bench, but something wasn't right. He was kicking around in his sleep, a tense expression on his face. At first, you just figured he was a stormy sleeper, but then you realized his hands were shaking. Nightmare? Yep, that's what it seemed like.
