While preparing for a class play, centaur Himeno Kimihara, who is playing the princess, ends up kissing her demon friend Nozomi Gokuraku after a male classmate who had originally hoped to play the prince role modified her script.

After finding Himeno modelling in a fashion magazine, Nozomi is roped into trying out some different fashions by Mitsuyo Akechi and her girlfriend Inukai after they hint Himeno might get expelled for having a part-time job.

After being approached by a boy with a love letter, Himeno is reluctant to accept it because she is worried about how her horse half would look naked. Hearing about her complex, Nozomi and Kyouko propose that they look at each other's private parts to put Himeno at ease.

As the girls discuss what kind of hairstyle would suit Himeno, she explains how her ancestry led her to have red hair.

Himeno goes to an archery meet with her underclassman, Ayaka Wakamaki, who acts strict towards her. Following some advice on her friends, Himeno helps Ayaka to loosen up by offering to go on a date with her.

Hime, Nozomi, and Kyouko decide to tail after Sassassul as she goes on a supposed date with a boy to a contemporary art museum, unaware that various organisations are keeping an eye on her too.

The girls participate in an RPG fantasy setting, fighting against monsters in a dungeon labyrinth, which turns out to be a story written by Mitsuyo.
