The name is Japanese for "firefly." This is reflected in his outfit which has the appearance of an insect's exoskeleton. He even has red flags attached to the back of his armor, representing the wings of a firefly. His special attacks evoke a firefly's glow and power of flight. Hotaru is a general from the realm of Seido, the Realm of Order, and devotes himself to preserving law and order at any cost. So much so that he could be described as a zealot. Hotaru is more of a lawful-type of neutral because (equivalent to Havik, who spreads discord and chaos) he preserves law and order and harshly punishes those who dare break it, but he is not above preserving it to a higher authority (such as the Dragon King Onaga).
