Nanashi was found by Galian in the middle of nowhere, lying alone and nearly dead due to a nasty wound in his stomach. After he was revived by him and taken to the bandit Guild of Luberia, it turned out he had no memory of his past or even his name, and thus Galian named him Nanashi (nameless). Galian would later betray Nanashi, joining the Chess Pieces and leaving him in charge of Luberia after erasing his memory of him. Nanashi's main goal is to track down the Chess Piece responsible for wiping out Luberia (Peta) and avenge his slain allies. Though through all his seriousness in killing Peta and avenging his comrades, Nanashi still has time for flirting. It's also implied that Nanashi is from earth, because Babbo says he has the same scent as Ginta.
