Oguma is the head of the Horns Conglomerate, and the adoptive farther of Louis, whom he bought from Black Market in the hopes of raising him to become his successor. He is stern, calculating, some would even say unfeeling, even treating his son as a business partner first before anything else. He almost never expresses how he feels about anything, but rather shows it through rational calculation, always knowing what to do as a result.

When voicing him, use a deep voice of a man in his late forties, and try to give off an intimidating business man aura.
