The only hope of defeating the monsters are artificially modified girls. Thanks to one of them, the modified girl Makina, the main monster was defeated and new monsters are no longer born. However, there are still many remaining monsters in the world. In the city of Tengetsu, where monster activity is particularly high, the newly created modified girl Evri is sent as reinforcements. Excited for her first mission, Evry arrives in the city with enthusiasm and determination.

- "I am Evri, the artificially modified girl, I will protect the peace of this city!”

However, the security in Tengetsu City leaves much to be desired. Despite her intention to protect the city, the residents aren't shy about harassing her: groping her tits, touching her ass, and subjecting her to endless sexual advances.

- "What's going on in this town?”

Evri became a modified girl to protect the world, but....

- "А? А? What's going on?”

- "Why are the residents groping my breasts?”
