Kurenai, Shinkurou

紅真九郎

The series' main protagonist. Despite his appearance and easygoing nature, he is a capable and strong worker employed by Benika as a dispute mediator. In his youth, he lost his family in a terrorist attack. Consequently, he became withdrawn from the world until he met Benika. He wished to be as strong as her so he could survive. Benika decided to leave him with the Hōzuki household. It was there that he trained his body extensively and learned Hōzuki-style martial arts.
His kind demeanor attracts considerable attention from the opposite gender, though he remains completely oblivious. In emergencies, he can produce a large 'horn' from his right elbow, classifying him as a "Type 1 Class 2 Fighting Demon". This special weapon was designed for the purpose of assassination. It allows him to use his full strength in combat, but shortens his lifespan. When forced to fight, his personality shifts to a more aggressive one.
There are differences between the anime and the manga in how Shinkurō is depicted. In the anime, Shinkurō is less confident and appears to have less control over the Hozuki horn.
