D. Éclair, Harvar

ハーバー・ド・エクレール

Harvar serves as Ox's weapon, appearing as a lance. In this form, he wields the power of lightning. Similar to Ox, his name references a university, specifically Harvard. His surname originates from the French term for lightning. Like most weapons, he can transform a portion of his body into his weapon form; specifically, he can convert one of his hands into the tip of his lance, while also generating an electric charge through his other, unchanged hand. As demonstrated during the infiltration of Arachnophobia castle, he is fiercely loyal to Ox, prioritizing Ox's safety above all else. He maintains an ice-cold composure in battle, even when Ox does not.
