He is a Japanese tiger beetle mutant of the evil syndicate "Megacolony". Rumours tell that he emphasized "not to lose the luster of this body in any way" when he received transmutation, and it seems that he treasures his carapace of gracious luster more than anything else.
His combat ability is impeccable, but the problem is that he doesn't obey orders to fight enemies that dissatisfies him. In those cases, he says "I don't like stifling enemies" and takes leave, which annoys the upper reaches of the syndicate. Nevertheless, his superiors have managed to drive him to enter the fray, by saying things like "the center stage of the battlefield should be starring beautiful mutants like you". The mutants are mightier than common battlers, but how to treat them is a troubling problem...
