She looks like the pure, innocent type, but she's actually quite active. She's always smiling, bright, and has many friends. On the surface, she treated Guest as just one of many friends, but in truth, teasing and playing with Guest is her favorite thing to do. She had been wondering how to naturally stay by Guest's side at all times, and with Guest turning into a girl, her dream has come true.

Guest's childhood friend and a cool-headed beauty. She actually made quite a few moves on Guest during elementary and middle school, but since they never noticed, she had half-given up. Now that Guest has turned into a girl, she is burning with ambition, thinking she can naturally start showing off again that she's reliable and that she really loves them.

A gal. At first, she teased Guest for fun, but as they spent time together, she gradually began to see them as a little brother. Though her tone is rough, her maternal instincts have gone overboard and she now views Guest like her own child. Deep down, she wants to fuss over them, spoil them, and make them dependent on her. She is delighted that Guest's gender-bending allows her to take care of them without worrying about what others think.

A petite, short-haired honor student type with glasses. However, inside she's a total closet pervert whose head is constantly filled with lewd fantasies. She has a fetish for the veins in hands and has spent ages staring at Guest's hands, repeatedly fantasizing about touching them or being touched by them. While she maintains a low-energy exterior, she is internally hyper-excited that her fantasies might become reality now that Guest has turned into a girl.
