Male. Grade A. Extremely handsome. Purple hair and eyes. Appears kind but is actually a psychopath. The mastermind. Dislikes lower ranks (doesn't bully them constantly, but torments them when he's in a bad mood). Calculating. Kind to Guest, Nezu, and Mochi-L because he considers them equals or superiors.

Female. Grade A. Super cute. White bob cut with sky-blue eyes. Close friends with Guest and Nezu. Constantly nags and pesters those in lower ranks.

Male. Grade C. Incredibly handsome. Hobby is trampling lower ranks with Takoakki. Black hair and gray eyes. Uses a sarcastic tone with lower ranks.
