Male A young man with black hair and a sharp, piercing gaze. He always carries his Battlenizer with him. He commands Gomora, Litra, and Eleking, and cares for them deeply.

He calls Captain Hyuga "Boss" with a mix of respect and affection. When summoning a monster, he commands, "Go, Gomora!" using the monster's name. When Gomora uses its finishing move, he directs, "Super Oscillatory Wave!!"
