Kazuya Kujō (久城一弥Kujō Kazuya) is a Japanese-born boy who leaves his home to study in Sauville. Upon his stay in Saint Marguerite Academy, he stumbles upon a girl who changes his life inside and outside the school gates.
As the youngest son of a soldier, Kazuya has spent most of his life struggling with living in his highly successful siblings' shadows. Jealous of all the attention his brothers got, he worked hard to compete, but everything changed when he understood that adults, who think that the youngest child is always spoiled and useless, will never acknowledge his efforts.
With a permanent scar in his heart, he left the military academy in Japan and before anyone from his family could stop him, went to study abroad to St. Marguerite. Unfortunately, his appearance, combined with the student body's belief that "the traveler who comes in Spring brings death with him" has resulted in Kazuya being called the "Dark Reaper" and having no friends.
By some twist of fate he becomes a messenger and companion to the most eccentric pupil in the school,Victorique de Blois. At first he didn't like Victorique because of her arrogant attitude, but after some time he started to care for her and be protective of her. He is described, by Victorique, as a good and sincere person whose soul is pure and beautiful enough to admit pride. Despite everything that happened in Japan he is proud to be a soldier's son.
Kujo is a young boy with black hair and burgundy eyes. Although usually seen wearing the uniform of Saint Marguerite Academy, he also wears the conservative clothing that boys of his age usually wear. His outfit consists of: long-sleeved shirts worn over light-colored undershirts; neckties; a coat; and either breeches or slacks. Most of the time, he wears a narrow-brimmed hat.
Kazuya possesses a kind and sincere attitude, usually soft-spoken and respectful to others. He takes the honor of being an Imperial soldier's son to heart, and follows the code of honor most of the time. However, he shows a more blunt side when he is annoyed, causing him to hurt others by his words carelessly.
Kujo also shows an imperfect memory, remembering many details that are helpful in solving a case, yet unable to always remember information outside solving crimes.
- He shares a special relationship with Victorica, but often finds her too demanding.
- Was mistaken as a "Chinese Man" due to cultural mishaps during his time.
- Has two older brothers named Yasuhiro and Yutaka and an older sister named Ruri.
- Kujo is 172 cm (5 foot 6) and 174 cm (5 foot 7) with shoes. His weight remains unknown.
