Shouta, a 25-year-old NEET, is mocked by his former female classmates who’ve all become successes, at their class reunion. A mysterious incident at the school pool throws him back in time and lets him deal with those same classmates back when they were fifth grade girls.

A high school senior named Yotaro thought he was an only child — until he met his real mother and discovered that she has 19 daughters, from 0 to 18 years old. He ends up living with his "true family."

Small for his age, Yukinari has been bullied and abused by girls all his life. Now in high school, he has developed a rare condition: whenever girls touch him, or even come close, he breaks out in hives. Imagine his surprise, when he is suddenly transported to the city of Seiren on a mystic world invisibly orbiting the Earth, and populated with vast numbers of women and very few men. Fortunately, he has a new friend, Miharu-chan, whose touch inexplicably doesn't affect him.

Two weeks have passed since the dilemma between Maiku, Karen and Miina was resolved, but their lives are more hectic than ever. Karen has become possessed in her newly discovered brother and Miina is desperate for attention as well, which leaves little time for Maiku to concentrate on his work. Therefore he decides to head out in the woods and set up a camp, where he can be work in peace. But, as always, we have Morino who is up to no good. To make things a bit more interesting, she organizes a field trip to Maiku's camp site, and encourages everyone to make some good summer memories.
