It’s been decided—Governor Hitoura will be giving a speech at Lewd Land. Determined to take him down, Fumino heads there with Misaki at her side. Meanwhile, backed by a mysterious benefactor, Junnosuke and his team clutch their brand-new weapons and set off for Lewd Land in search of Fumino. Misaki slips past FS’s ironclad security and goes full throttle through Lewd Land on a pleasure bicycle! Junnosuke and the others join the fray, unleashing total chaos!! But just when they think they’ve got the upper hand, the deadliest lewd assassin appears… and the greatest virgin crisis in history begins—!?

After developing a soft spot for the Future SHO, Junnosuke aborts the operation, and they fail to hand over Fumino to their benefactor by the end of Cumming-Of-Age Day. Ashamed of the trouble he caused, he resigns from the Future SHO, and returns to the NLNS base with no strategy in mind. His benefactor gives him a final warning, "If you fail to hand over Fumino again, I will cut off all support". The Future SHO also begins posting wanted posters of Junnosuke's cock around town. Junnosuke is overcome with guilt, believing everything is his fault. Unable to see him like that, Nanase reaches out to him...

The NLNS succeeds in saving Fumino and Misaki, but at a huge sacrifice. Junnosuke has lost his virginity forever... That's not to say he had pervert sex with the love of his life! Pulling himself together, he welcomes the new members on his team! Meanwhile, the Future SHO also starts recruiting new members to go up against the Anti-Copulation Force. Junnosuke takes this opportunity to sneak into the Future SHO, but what awaits him after enrollment is a training so terrifying that it makes his pubes crawl—!

The NLNS disguise themselves as Hamedori-kun to confuse the enemy! They use vibrators and dick-shaped drones to launch their attack to get past the FS! Meanwhile, Hinami's Hamedori head is torn off exposing her true self to Rei Tadasugawa, who was fighting her...!? The guillotine ship shows no mercy and departs the giant water gate... Will the light of day come at all after the pervert night?

Student Council President Touka Reizeiin declares the opening of the lewdest festival of all—“Athletic Cumpetition”! Seizing the opportunity, Junnosuke and his team plan a covert infiltration of the student council room to steal intel on "Fumino Kotoyose." But the lewd festival is no joke! Erotic competition! Erotic competition!! Erotic competition!!! Barely managing to cling to his virginity, Junnosuke presses on toward his true objective: the student council room. But waiting for him there is Misaki—making an epic anal contraction...!?

Item creation to outsmart the FS, securing every escape route, and Nanase's home cooking that achieves perfect nutrition. With Nanase as their ally, Junnosuke and Masane begin their plan to destroy the perverted ordinance. And on Seiran Island, there were other girls besides them who were also struggling! Hinami Watarai, a virgin who is never propositioned for sex by anyone due to her youthful appearance! Azumi Misaki, a virgin with a terrifying libido, but who doesn't want to show her plump body to others! One day, a major incident befalls Hinami!?

Junnosuke, now an official member of the Future SHO, receives an order from his benefactor that Fumino will be handed over on the Cumming-Of-Age Day. The NLNS devise a plan towards the big day, while the Future SHO have successfully created a clone of the Anti-Copulation Force leader's cock via Ikuko's vagina! Amidst all this, Junnosuke gets promoted as the school president, Touka Reizeiin's personal assistant!! But upon spending time with the Future SHO and sharing conversations between them, he comes to realize that they too, have firm beliefs of their own...

To protect Hinami from the “Preschooler Man,” Junnosuke proudly declares himself part of the Anti-Copulation Force. However, despite appearances, Hinami turned out to be a full-fledged adult!! In the end, Junnosuke and his group had unwittingly sabotaged her chance at sex. Naturally, the sinister hand of FS draws near! He gives everything he’s got to flee, but after exhausting all his weapons, he finds himself in a desperate, do-or-die chastity crisis!! Just when all hope seems lost, a terrifying long-range sniper shot from a girl in a kimono saves Junnosuke from the brink!? And to make matters even more chaotic—Misaki, having heard the commotion, rushes to the scene...!!

Nanase, who protected Junnosuke, gets detained as the ringleader of the Anti-Copulation Force, and is set to receive the dick penalty on the guillotine ship. Despite attempting to stop this, his benefactor give orders to take advantage of the guillotine ship's departure and hand over Fumino. Bracing himself, Junnosuke decides to negotiate directly with Touka over Nanase's release. However, he finds out her terrifying plan that makes use of his super-sized dick--The Magical Cock! Touka offers to release Nanase and cooperate with Junnosuke, but in exchange for offering up his cock...
