Dr Narutakis Quest to Save Japan with 100 Sperm Samples Race

Dr. Narutaki, a genius scientist, aims to restore true Japanese masculinity by collecting semen from 100 men. To achieve this, he enlists Marin, a charming girl from an all-girls school, outfitting her in a magical suit that adapts to men’s desires and only comes off after gathering all samples. Meanwhile, Southpole One, a sexaroid created by Narutaki’s assistant, competes by depleting men’s stamina first, turning the mission into a thrilling race. Determined to secure Japan’s future, Narutaki and Marin press on with their unconventional quest.
