Balmung

Balmung (バルムンク, Barumunku), also referred to as Lord Balmung and "Balmung of Azure Sky", is a legendary player in The World. He gains his title by defeating an event thought to be unbeatable with his partner, Orca, causing them to be known as "The Descendants of Fianna." He is a Blademaster, who is given white wings after the event as a reward. He can use them to float and jump higher than other players. Balmung is originally very formal and assertive of his views, following a strict moral code of doing good in The World, leading some to consider him arrogant or rude at times. He truly loves The World, and takes playing it very seriously, to the point of investigating disturbances within it personally and refusing to speak with hackers or associate with them. By the time of .hack//Legend of the Twilight he's much more care-free and less serious with new players, though still completely business-like with his associates.
