Sephirotht is a guy from Warflame. Friendzoned by Mistress_Zelda, a jerk to everyone else. Kind of selfabsorbed.
Shikamarukun often taunts him for being old, however Seph is 4 years younger than the strange 27 year-old who many believe has no life, going on a website and board where the majority is under 20 years old and actively calling the children immature when, that's kind of what kids are supposed to be... Not that he bothers to talk to them.
Sephirotht's name is close to a Final Fantasy villain: Sephiroth.
