Ryusei Yanagi

Ryuusei Yanagi (柳劉 生) is the doctor attached to F Squad specializing in the hemotology of the redeye race. His job is to watch over the devils in F Squad and keep them healthy by giving them check-ups and providing sedatives. He originally worked at the Tokyo Metropolitan Karasuma Hospital. He was apparently a punk in his youth.

Appearance
Yanagi is a man in his early thirties with an average build and considerably shorter height. He wears oval-shaped glasses over his light brown eyes, and his black hair is distinctively kept shaved.

Personality
Yanagi is a very calm and level-headed man. He is very knowledgeable about devils, and does his best to keep the devils in his squad healthy. He is very serious about that job and sympathizes with devils. He is kind caring as he takes other peoples feelings to heart and consideration at all time, and he also tries to help out others as much as possible. However, when he becomes provoked by others or becomes upset, he will become rough and angry, making his traits from his younger days as an apparent punk visible.
