Hajiki is the main protagonist in Gad Guard. The short-tempered and somewhat jaded boy works as a courier for Hachisuka Express, to help his mother, Kyoko, pay the bills.

The eldest child and only son of the Sanada family, Hajiki works as a delivery boy in Unit Blue. A bit of a degenerate and a punk at first, Hajiki skips school, races the cops on his skateboard or moped, and hangs out at all hours with his loser punk friends for lack of anything better to do. While he claims to have no dreams, it appears that there is more to the bed-head-plagued boy than meets the eye, as really, what sixteen-year-old has no hopes for the future? (from Wikipedia)
