He is very dependable, although he gets embarrassed easily when teased.

He has two past lives, the first being a Shirogane named Flaga, whom was in love with Satsuki's past life Sarasha despite being her brother, and the second being a Kuroma named Shu Saura, whom was in a relationship with Shizuno's past life. Due to having memories of both lives, he is known as an Ancient Dragon and is both a Shirogane and a Kuroma.

His sword is a "Saratiga" which is a straight katana while as a Kuroma his dark art is the "Black Gehenna" that he infuses into his sword to maximize its destructive capability called the "Yin Yang Kurikara." His other abilities include the "Ouroboros," which is a water spell that allows him to flood vast areas and to walk on water, as well as the "Gorikitsu," which allows him to maximize his plana.
