This romance visual novel explores the question of gender integration at a private school. A curious series of events leads to our hero becoming the only boy at a prestigious girls' academy... But over 99% of the girls are against integration!

Yuuta is just your typical guy who enjoys an ordinary school life with his childhood friend Yuuna. Suddenly one day, a mansion appeared in his backyard, inhabited by the vampire princess Luce. One by one, other other-worldly princesses came to him, all of whom had made a childhood promise to be his bride when they grew up. He didn’t remember the promises, but then Yuuna also joined into the fray and proclaimed that she’s the one who will always be with him.

The main character and his friends are attending their class in a quiet academy like normal students when a UFO suddenly passes overhead. The whole academy begins to panic and a beautiful, female alien appears from the UFO. She claims she traversed vast reaches of space in order to tie the knot with Yuusaku. Meanwhile, Yuusaku is utterly confused. As she tries to press him into marriage, she uncovers his secret stash of porn and begins using knowledge of cosplay from that in order to seduce him. The other heroine, his childhood friend, joins in the fuss over Yuusaku caused by the alien’s mother, friend, rival, and even space pirates. On top of all this, secret agents from another country begin targeting the Aliens’ advanced technology…
