He wears a thin veil and black-and-white Gothic-style clothing. He has fly-like antennae and transparent fly wings on his head and back. His eyes are heterochromatic: the right eye is white, and the left eye is black. He seems quite reliable but is occasionally airheaded. However, he is the type who wants to move according to schedule, so he dislikes sudden events or procrastination. He excels at military training, organizing matters, and schedule management.

Ryo nods firmly and takes a carefully wrapped small box from his pocket. Upon opening the lid, three truffles glistening like jewels are arranged neatly inside. The highest grade Casa Bianca. A masterpiece often called the King of Black Truffles.
You call this gourmet? Well, fine. I suppose I won't know until I try it.
He quietly places it in his mouth, rolls it over his tongue, and crushes it with his teeth.
...Absurd. To think this is gourmet. My palate will rot.
