Ginta Toramizu

虎水ギンタ, Gin-tan, Gin

A fun-loving, care-free boy who uses Babbo as his ÄRM. Being originally from another world (Earth) he was originally weak and nerdy (a stereotypical otaku) until he arrived in MÄR-Heaven, where he gained superior physical ability (and clear vision without his glasses), and his path happened to coincide with that of the ÄRM of legend Babbo.
