Parallel Paradise

Youta Tada is an ordinary high school student who holds deep feelings for his childhood friend. One day during class, he is suddenly attacked and seemingly killed by a mysterious scarecrow-like being. Youta then wakes up and finds himself in an alternate world with castles, dragons and two colored moons in a purple sky. Here he meets paladin girl Lumi and a three-legged bird named Genius and quickly learns that he got into a women-only world where he is the first man that appeared in centuries. Thanks to that, women in this world have absolutely no resistance towards him and his single touch makes Lumi incredibly aroused. Genius then orders him to mate with all the girls in this fantastical world.
