Three poor souls who had their memories removed.
These three “followers” were freed from one of the prisons of Harpia by Minato, whereupon they joined up with the party mainly because they couldn’t remember who they used to be. The evil wizard “V” had removed their memories with the Info Cube, and the Cube is presumably the only way to restore their memories. The sturdiest of the three grew to be friends with Minato, who gifted him a greataxe and a suit of chainmail. Apart from this, they are practically useless in high-pressure situations, due to the fact that they have no class abilities and are constantly shaken or frightened.
