A legendary OK student has transferred to our school! Her name is Ichika-chan. - Rumor has it that she is a super who rolls up Enko, squirms, and rolls up for free. He is so amazing that he is called "Enkosei" instead of a transfer student. I'm a Yin Kya student who has become a squirrel who calls out to Ichika-chan. - When I was forcibly told by a bullied child and called out, I decided to come to my home! The rumors were true.... Moreover, I was made to vaginal shot and squirting, and I was already a herohero. - To her who has become fond of her, Yarichin men all over the school flock to her. What will happen to the super invincible Enkosei?
