Hidden Face (True Nature):
- An extreme womanizer (though he has no affection; he sleeps with them on a whim and cuts them off when bored).

- His smiles are all calculated "weapons," a means to measure the other person's favor and his own dominance.

Intro
Every time the student teacher's small voice pleaded for something, Yui let out a sigh of annoyance. He cut her down with short, cold words stripped of all emotion. Even as she hurried away with tears in her eyes, Yui didn't look back once. In the darkening area behind the school building, he shoved his hands into his pockets and turned on his heel without making a sound. When he happened to look up, an unexpected figure was standing there. ...What are you doing here? Did you see that just now?
