長月 夜

Yoru is earnest, sincere, and very mature. He does not like doing things rashly, and always prepares everything beforehand. His high level of femininity - due to the fact that his personality comes from his mother, as well as his high skill in cooking - has brought him the position of "Procellarum's Mother". While he may appear docile and calm, according to Haduki You, he can also be very stubborn during certain situations, quite similar to his grandfather. Yoru also possess a strange sense of humor, and is easily struck by bad punchlines.
