The protagonist, Ryuki Kirishima, has just become an adult a few days ago. When he goes to the river with his friends, he strips off his clothes and jumps in completely naked!! As he tries to proudly show off that experience he had a little while ago, he finds Kiriru squatting in front of him. As punishment for attempting to break the promise, Kiriru orders him to take care of the camera, and they start filming with the friends who were there. Seeing that scene, Ryuki feels jealousy and regret, and he vents his helpless feelings onto Kiriru! To create summer memories, the virgin hunter Kiriru descends!! Squeezing every last drop in a 5P blue◯.
