Notto Sexaroid Eurie 1

Modified girls are the only ones who can defeat monsters.
Thanks to the efforts of one of them, Modified Girl Makina, the original monster was defeated, and no new monsters have been born.
However, many monster swarms still remain in the world and Tengetsu Town is heavily affected by monsters.
Eurie, a new type of modified girl, is dispatched there, excited and in high spirits for her long-awaited first mission.
