Bill

"I am the bartender, cook, janitor, human janitor, and the security guard when everyone's absent.And the cute girl over there?That's my wife.Oh...Yeah. Oh."

- Bill talking to a customer Bill (ビル, Biru), more commonly nicknamed Bill the Lizard (ビルザリザード, Biru Za Rizādo), is the bartender, cook, janitor and the security guard of the Under Wonder Guild, being one of the few factionless Mages within it. Formerly a slave within Bosco, he was to be auctioned off for a high price due to his abnormal appearance, possessing the head of a reptile, before escaping, subsequently meeting Nathalia Bortros, who nursed him back to health.

Sometime after moving out of Bosco, the two got married, and joined Under Wonder. The two both own the guild's bar, serving meals and beverages to the Guild members, as well as doubling as the guardians of the base. Despite not belonging to any faction, Bill is considered an S-Class Candidate, despite his clear desire to stay out of violent situations.
