Yadorishi Otome no Chikai to Mahou

After fixing up a stuffed toy he comes across in a park, the protagonist Shinomiya Hibiki, get caught up in a strange event.

Like receiving gratitude in folk tales.

Hibiki gains a glittering, mysterious mark—— A magic symbol. The light from the symbol gradually envelops him, transforming him into a magical girl.

"......What's going on, what's this......"

While at a complete lost and unable to grasp the situation, before Hibiki, a girl appears.

"I must protect you."

Led by the girl who claims to be a magical girl as well, Hibiki arrives at a Western-styled manor called "Otogi-kan," which severs as a dormitory for students at the prestigious Aether Girls' Academy, a gathering place for magical girls.

An extraordinary combination of cross-dressing and magic—— The story of these captive maidens is about to change.
