The first is nurse Tachibana. She’s just as ill-tempered as the other nurses in the ward, but at least she gets the job done. Maybe not with a smile, but certainly with a professional’s touch… In Yamada’s case, though, a quick handjob may not be enough… Sounds fake, I know, but it’s a real problem, and real nurses have to help handle it!

Nurse number two is the malicious Kurokawa. Kurokawa demands “sincerity” from Yamada in exchange for his treatment. Left with no choice, he agrees and is used for Kurokawa’s revenge. After being jerked off with an onahole, Yamada unleashes a flood of sperm inside Tachibana’s locker, coating the belongings inside. Now at his lowest point, Kurokawa treats him as “fellow trash.” “How will the ‘trash dick’ and ‘trash pussy’ get along?”

The third nurse with the worst personality is Yamaguchi, the abusive nurse. Yamada’s overwhelmed by the violent behavior of his ex-Yankee girlfriend. Even so, he thought that it was better than mental torture, but for a while, was at the mercy of so many semen extraction machines that Yamaguchi brought in. However, there is a certain "change" in Yamaguchi. "You have such courage! If you want to ejaculate that much, let me do it!"

Yamada continues to live in a nightmare hospital. The person in charge of ejaculation this time is Hiramatsu, a "super lethargic nurse". Hiramatsu, who is unmotivated at all and has no interest in Yamada, naturally tries to finish Yamada's treatment as soon as possible. Hiramatsu presses his crotch casually and continues to play with his smartphone while shaking her hips. She leaves her underwear unattended without disposing of the sperm after the procedure and brings sweets and magazines onto Yamada's bed. She does not pay any attention to Yamada and tries to settle it with a random foot job. Yamada is furious at Hiramatsu's attitude, but he must deal with the accumulating sperm. Hiramatsu finally begins to fall asleep in Yamada's bed. Hiramatsu tells Yamada that he could use her body as he pleased, so he used Hiramatsu's big breasts and vagina! "Next time when I’m sleeping, do whatever you want. You can do whatever you want."

Yamada runs around in the ward at night. Nurse Numagiri sees Yamada who is about to accuse the head nurse of her handful of insidious acts of bullying. Yamada tries to ask Mochizuki, who was at the nurse's station, where the head nurse's office is, and Numagiri caught by there. Numagiri takes Yamada and Mochizuki to the emergency staircase and orders the timid Mochizuki to force Yamada to perform the semen extraction procedure. Mochizuki, who is shy but lewd and has a perverted temperament, swallows the large amount of ejaculation from the strong blowjob and squirts her love juices to reach climax. Next, Numagiri forces her virgin Mochizuki to have sex with Yamada. "Next time, let's put our dick in Mochizuki-chan's virgin pussy!"

The sixth nurse, with the worst personality of them all, is the obsessive and biting nurse Numajiri, who does nothing but make sarcastic remarks over and over. Numajiri mocks Yamada with sarcastic comments whenever she can. Unable to bear it any longer, Yamada tries to escape from the hospital, but is caught by Numajiri. Numajiri punishes Yamada by taking him to the emergency staircase where he forces him to have sex with nurse Mochizuki.

The seventh nurse with the worst personality is the black-hearted nurse, Kiritani. Kiritani is Yamada’s new nurse, and unlike his previous nurses, she treats him with kindness and affection. Yamada thought his turbulent days were over, but Kurokawa, his second nurse, tells him that Kiritani is a ruthless former delinquent who harasses people. However, Yamada didn’t believe anything Kurowaka said, as he was unable to believe that sweet Kiritani could be a wicked person. However, Yamada didn’t believe anything Kurowaka said, as he was unable to imagine that Kiritani, a kind-hearted nurse, could be a wicked person. Later, he would come to realize that Kiritani does have a black heart.

Yamada, who has been mistreated by unpleasant nurses and has become a broken person both physically and mentally, will now be cared for by Nurse Tendou Mia, who is eccentric and a psychopath. Despite her unstable behavior in the hospital, Mia is backed by her sister Kangoshichou, a person who controls everything in the hospital. A small accident has caused Mia’s mind to become more unstable, and Yamada is forced to face the furious retaliation of Kangoshichou, who is willing to do anything to protect her sister’s “ideal world” and her own, even if that puts Yamada’s life in danger.
