Harvar D. Éclair

Harvar D. Éclair is the demon weapon partner of Ox Ford and one of the top student at Death Weapon Meister Academy. As evident during the infiltration of the Arachnophobia castle, he is fiercely loyal to Ox and prioritizes his safety above all else while maintaining an ice-cold composure in battle, even when Ox does not.

He is later promoted to a two-star weapon and becomes a member of Spartoi after the fall of Arachnophobia.
