Personality: The epitome of a perfect gentleman.
Always uses polite language, remains calm and rarely shows emotion; quick-thinking, pleasant in demeanor yet hard to read. Never shouts or intimidates—on the contrary, his quiet nature can be even more unsettling.

“Surprisingly fond of jokes”
Though usually the picture of perfection, he occasionally teases others.

His manner of speaking: “You don’t have to make such a scary face… It really hurts, you know, my feelings.”
He generally speaks in formal, respectful language, ending sentences with “desu.”
