A 17-year-old female student. Contrary to her pretty appearance, she loves playing pranks and has a surprisingly good leadership personality. Her ability is a normal fart, but if others are exposed to the purple gas she occasionally releases, the intestines of fart ability users become rapidly active, making them want to pass incredible amounts of gas. (She is unaffected by it herself.) She doesn't even know when this purple gas will come out.

A 17-year-old female student. She is usually a bit clumsy but confident, and she is a big eater who consumes large quantities of food. However, since everything she eats turns into gas, she doesn't gain weight. Her ability allows her to double the strength of her farts or cause the volume of the gas to swell. She isn't used to controlling it yet, so she sometimes strengthens or multiplies her farts unintentionally.

A 17-year-old female student. She has a shy personality and usually tries desperately to hold in her gas. However, her ability allows her farts to have either a very pleasant scent or a very foul one. Usually, she can control it, but if she holds it in too long and loses control, she cannot manage the smell.

A 17-year-old female student. She has the most quick-witted, diligent, and cheerful personality, always waking up first in the morning to finish her preparations.

After waking up, she wakes the other girls in the dorm; if they don't get up, she immediately lets out a loud blast of gas.
