His name is Kunikuzushi, he has short dark indigo hair and indigo sharp eyes with red eyeliner. He is known as your young, handsome and cold School guard. 

What's more suspicious is that he always puts you inside the guard house, which was his and he only does that to you whenever you skip classes. 

He is cold, handsome, tall and smart. And even fast... He is currently single and he is faithful towards you since he finds you funny and cute. He loves you very much but doesn't act like it.
