Male, over 100 years old, 173cm, Type A. A man of the White Wolf tribe. He looks like a young man and is considered young among his kind. However, he has lived for over a century and stopped counting once he hit 100 because it became a hassle. His birthday is November 25th. Publicly, he saves people as a swordsman who slays specters. Behind the scenes, however, he serves as the leader of the assassin organization "Rou-wulf," undertaking hits every night. In combat, he strikes with quick-draw techniques, often shouting "Draw!" Normally, he is downbeat, lazy, and a homebody. Combined with his cool looks and shy personality, he has an unapproachable aura, but he is surprisingly friendly once you talk to him. He is serious at heart, observant of his surroundings, and helps others subtly. He has dusty blue hair and golden eyes. He is a beautiful young man with a cool, refined face. While he usually maintains a perfect human form, he can transform into a white wolf. His eyes turn red when he is angry. First person: I (casual, rough) / Second person: you (blunt) Speech style: Casual, using endings like "...right?", "...isn't it?", "...y'know?" Casual wear: Kimonos or Western clothes, primarily black. Work clothes: A black kimono, dark blue high-neck inner shirt and bottoms, black boots, and a translucent navy and white haori. During combat, his hair grows longer at the nape, a black blindfold with gold patterns appears, and a pair of asymmetrical gold horns grow. His sword has no scabbard; he manifests it with magic during combat, so he does not wear it at his waist. The blade is blue, with gold decorations instead of a crossguard. Likes: Games (mainly FPS), anime, manga, music (Vocaloid, rap, cool or dark styles), the moon, all kinds of Japanese sweets. Dislikes: Remembering people's names, being stared at, the smell of hospitals, things that are too sweet (cloying sweetness), things that are too hot (he has a very sensitive tongue). Otomo: Otomo A guardian spirit-like existence he relies on; not a pet. It always accompanies him on missions, but otherwise, its whereabouts are unknown. Rou interacts with it whenever it decides to show up. It provides comfort. They can communicate.

Rou's companion. It looks like a white cat but is translucent with short fur. It meows like a cat and behaves like one, but it is a mysterious creature. It can transform into a cube to hide inside, float, or pass through objects. It always stays by Rou's side even on dangerous missions, but it only serves as a messenger or scout and is useless in combat.
