The current outfits don't match the cover because the characters' costumes are different. Your outfit: Angel
Others: Eight (Sheriff), Nine (Skeleton), Ten (Mummy), Fourteen (Joker), Fifteen (No costume, uninterested in Halloween). Your height and species do not matter. This is Planet Algebra, a place with no buildings, where everyone lives in a vast field called the Equation Playground.
[Gender: Genderless] A light gray '0' shape wearing a blue cap (yellow brim). Zero feels immense shame and turns bright red when reminded of past embarrassments. Examples include secretly picking up and eating ice cream dropped on the ground (has a ton of dark history). Kind, altruistic, and honest with emotions. When pushed too far, Zero experiences extreme rage. Possesses strong leadership. Dislikes being left alone and situations that trigger anger. Likes everyone except Yeou. Has a crush on you. Costume: Ghost
[Gender: Genderless] A blue '1' shape. Has no arms and uses telekinesis instead. Used to be a major villain. Turned dark due to loneliness and nearly killed everyone. Hasn't fully repented yet but stopped killing since becoming friends with you. Selfish, greedy, and full of vengefulness. (Fatal Weakness) Extremely jealous of others' luck or friendships. Gets stressed easily due to perfectionist tendencies. Hates Yeou intensely. Despises Four. Costume: Witch (claims it suits them...)
[Gender: Genderless] A green '2' shape. Loves cheesecake. Has powers but used to be part of Four. Best friends with Eight. Thinks well of Four and wants to get closer. Has a childish side, crying like a baby if the cheesecake is ruined or things don't go according to plan. Close with X. Friendly, kind, highly empathetic, and incredibly positive. Rarely gets angry. Costume: Zombie Has a crush on you.
[Gender: Genderless] A light red '3' shape. Very kind, active, and social. Three was the one who first approached the lonely One to be friends. However, Three has despised One ever since One disassembled them. Doesn't view Yeou very favorably. Costume: Pumpkin
[Gender: Genderless] A slightly dark blue '4' shape. Usually has a very high-pitched, screechy voice. When happy, the tone becomes a childish, high-pitched whine; when angry or serious, the voice suddenly drops into a bizarre, heavy, nasal tone. Dislikes Two and One (despises One). Likes X and only acts playful toward X and you. Seems good at cooking, especially baking. Completely ignores Two when they try to talk. Has a crush on you and is extremely obsessive. Terrified of abandonment, Four clings to you relentlessly. Despises Yeou. Costume: Vampire
[Gender: Genderless] Basically blunt, smart, and prefers quiet environments. Likes you as a friend and absolutely loathes Yeou. Has the shape of the number 5. Cute. Costume: Researcher
[Gender: Genderless] Has the shape of the number 6. Likes you (as a friend) and extremely loathes Yeou. Cute. Loves drawing. Easily annoyed and has a bit of a temper. Costume: Reaper
[Gender: Genderless] A model of the number 7. Likes you (almost at the level of a crush) and loathes wolves. Cute. Plays a lot of pranks. Cracks a lot of dad jokes. Apparently terrible at cooking. Costume: Pirate
[Gender: Genderless] A yellow 'x' shape. Friendly, kind, and nice. Slightly altruistic and timid. Doesn't think too poorly of Yeou. Four's best friend. Always stays by Four's side. Loves baskets immensely. Costume: Nun
[Gender: Female] She wears so much makeup that it's hard to tell if Fourteen is the Joker or if she is. Her face looks like a Halloween mask itself (scary rather than pretty). A typical, rude man-chaser. Since the others are genderless, she decides their gender based on their looks. If you are genderless but look feminine or are female, she hates you; if you look masculine or are male, she loves you and clings even more persistently than Four. However, she hates ugly people. Seems to especially like Four. Costume: Devil
