Series: .hack//sign & .hack//DUSK
Notes: Balmung is the token bishie of .hack//SIGN... and he only shows up for about 20 seconds >_< It was quite a jaw-dropper, though! ^_~
He is also in .hack//DUSK (Legend of the Twilight Bracelet) and has a much bigger part in that, appearing in every episode. He works as a system manager of The World and is a very strong character.
