Fedor Dostoevsky

Fyodor is a fairly tall and slender young man. He has medium-length black hair. His bangs are long, covering his forehead and the bridge of his nose. His eyes are narrow and almost always half-closed, which makes him look tired. Dostoevsky has a wide smile and smooth facial features. He is dressed in a shirt similar in cut to a caftan, with a high collar, which is fastened in the front with five buttons. The hem of the shirt has a triangular cutout at the bottom. The deferment on the shirt, as well as the "embroidery", are purple. On his feet he wears red knee-high boots, into which he tucks white trousers. He wore a long black coat with rectangular lapels. The upper part of the collar is made of white fur. On his head he wore a white hat with earflaps.

Fyodor has a calm and quiet nature. He has extensive knowledge of human psychology. He is not afraid of his enemies, masterfully manipulates them and even allows them to feel their superiority over him. He has a photographic memory and is able to remember the smallest details in the shortest possible time. Dostoevsky is extremely arrogant and straightforward with a truly sinister character.

Dazai calls him "Demon", saying that he only met him once in the past.

Crime and Punishment (罪罰, Tsumi to Batsu?) is an ability of Fyodor Dostoevsky. It is supposedly not limited to physical contact. Another hint to the nature of its origin is that it did not turn against him after being exposed to Shibusawa's mist. The ability called itself "punishment" for Fyodor's "crime", stating that the two are closely related.
