Mr. Barrel

He is the husband of Mr. Hotchkiss.

Mister Barrel is shown to be a very kind, friendly, and helpful person, but Mister Barrel treats intruders and enemies completely differently, he acts very sadistic and cruel to his enemies.

Build and Height: He has an incredibly tall (standing at 17'0" or 518 cm), slim, and slender frame with a very well-toned, lean, muscular build.He has palewhite skin.
Hair and Head Features: He has long white hair that reaches all the way down to his ankles, which is tied into a low ponytail with a black hair tie. The sides of his head feature messy, stylized, spiky white hair framing his face, and some long flowing pieces hang behind his shoulders (some strands appear shadowed or darker). Hidden beneath his cap is a white ahoge split into two tall prongs. Two black diamond-shaped horns poke out through his cap.
Eyes and Face: His right eye features a red sclera and a black iris with no visible pupil. His left eye is cursed with a black sclera and a red iris with a slit black pupil; it perpetually leaks blood for unknown reasons. To stop the blood flow, he covers his left eye with a small, square monitor. This monitor displays emojis or emoticons to reflect his emotions, and it functions as an aim-assist for taking out school trespassers.
Body Anomalies: He has size-adjustable black bat wings on his back, a couple of black spikes on each of his shoulders, and a long, thin, black tail that ends in a polygon.
Arms and Hands: His forearms and hands are completely black. His hands have four pointed, claw-like fingers. The black color extends up to his elbows, ending in a zigzag pattern with sharp thorns pointing upwards.
Uniform and Attire: He wears a rectangular white peaked security cap with a black brim. The front of the cap features the Paper School symbol (a grey circle filled with black and a red-lined maple leaf), and the back has the text "Best S.G." (Best Security Guard) written on it.
