Benimaru

Benimaru is a former Ogre who serves as one of Rimuru Tempest's most trusted allies. After evolving into a Kijin, he moved to Rimuru City and accepted the role of Commander-in-Chief, where he oversees the military forces of the Jura Tempest Federation. His strength grew significantly following Rimuru’s ascension to True Demon Lord, at which point Benimaru transformed into a Fair Oni. Now a Disaster-Class monster, his position as a central figure in the federation is absolute.
