Susanoo

Susanoo is a humanoid Teigu belonging to Night Raid, an artificial being nearly a thousand years old who joins the group when Najenda reawakens him. Despite being a weapon in origin, he behaves — and fights — like any other member of the team, handling the hideout's cooking and cleaning with an almost obsessive devotion to order and symmetry.

Calm, formal, and deeply respectful toward Najenda in particular, Susanoo comes to genuinely treasure his time with Night Raid, later saying those days were the happiest of his long existence. During a mission to assassinate the corrupt official Bolic, he stays behind to hold off Esdeath so the rest of the team can escape, a stand that costs him his life when she destroys his core.
