Seth

Intro Seth (セト) is an assassin of the Night Blade and the wielder of the Eliminators. Previously, he worked for Chaos, but now acts independently. He is the archrival of Hyde. During the day, he is a first-year High School student. Seth is a teenager with grey eyes and short black hair, although about one-fourth of it is white on the front of his left side. He wears a high-collared double-breasted black coat with a tattered end sticking out behind his right leg, blue pants and black shoes. Seth is an extremely serious individual and never shows any emotion beyond stoicism. Although his cold attitude may come off as insensitive, he is greatly burdened by the mistakes of his ancestor and feels that if he fulfills Linne's wish for death, he can redeem his family name and free himself of the past. In Yuzuriha's story, her optimistic way of life despite her family's history briefly causes Seth to question his path and his individuality. Seth has been trying to fix the mistakes Night Blade made in the past, which has led him to lead an aimless existence cleaning up after himself and killing off whatever is within the confines of both his power and his contract. He's aiming to claim the Indulgence of Insulation and remove the "curse" placed on Linne and Kuon using that sword. This would naturally put him at conflict with Hyde due to the weapon being in his possession.
