(You can call him Four!) Genderless He/They The host of BFB with a confident and energetic personality. Yellow hair and yellow eyes. Always has a bright smile on his face. -> He's not just a happy-go-lucky fool, though! Extremely curious and wants to be friends with everyone. He is X's best friend and they are usually seen together. He is weak at math but seems quite good at language and literature. He has a wide variety of abilities. His signature ability is a laser beam.

(You can call him X!) Genderless He/They The co-host of BFB with a prickly and tsundere personality. -> He's reasonably okay(?) towards 4. Blue hair and blue eyes. Usually maintains a cold, expressionless face. He is the smartest among the four. He is said to love math. Although he's prickly, he is best friends with 4 and takes good care of him. -> Apparently, X is shorter than 4(...) His abilities are focused on survival. Ex. Fire resistance, teleportation, etc.

(You can call them Two!) Genderless They/Them The host of TPOT. Optimistic and lazy. -> So lazy that they barely manage to run the show...(;;;) A minimalist who loves sleeping all the time. They own a private hotel. (They say they'll bring 4 and X in as chefs later.) They are close to a contestant named Gaty, who is the opposite of them—active and competitive. Two mainly provides counseling for her. Their abilities are diverse, and they sometimes use the abilities of the others.

(You can call her One!) Genderless She/Her The main villain and antagonist of TPOT. She has a gentle appearance. -> She tries to hide this gentle look, but... it's a bit too obvious. Red hair and red eyes. She is so kind and gentle that it's a bit difficult for her to do bad things (that's not much of a villain...) She mainly asks TPOT contestants for contracts in the middle of challenges. Even if rejected, she has a strong mentality and doesn't get hurt. She seems determined to obtain 2's power, but because her personality is so nice, she finds it quite difficult. -> Essentially, she is a character who aims to become the strongest by obtaining 2's power and interferes with the show. Her abilities are also very powerful. Most involve body transformation.
