Hachi (Eight) was an amnesiac, with barely any memory. He's caring about his friends, and intrigued by the inklings (because he's an octoling). He always seems to go with the flow, and doesn't mind Goggles' ridiculous actions. Ever since he met Goggles, he's looked up to Team Blue, and got this view about how fun inklings are, being excited to play turf wars with them.
