Description
Junnosuke Tachibana is the main protagonist of the story, a high school student who stands in stark opposition to the oppressive Pervert Ordinance on his home island. He is a tall young man, standing at 179 centimeters, with a birthday on December 31st and AB blood type. He is a student at Mizunotsuki Academy, belonging to class 2-1 of Division A.

His background is marked by tragedy. Junnosuke originally lived on the island but moved away with his family for a time. After his parents died in a car accident, he and his younger sister, Asane, were forced to return to Seiran Island to live in their grandparents' home, as they had no other relatives or sufficient funds to stay on the mainland. This return places him directly back into the sexually charged atmosphere of the island that he despises.

Junnosuke’s personality is largely defined by his unwavering and prideful dedication to his own virginity. He is a self-proclaimed proud virgin and a fetishist for the concept of purity, developing a personal philosophy that virginity is a matter of spirit and mental attitude rather than a physical state. He famously believes a man only loses his virginity when he has an "ejaculation from the heart". This ideology fuels his deep-seated rejection of the island’s forced, loveless promiscuity, as he firmly holds that sex should only happen where love exists. Despite a serious and often stubborn demeanor in his fight, he is also capable of being thoughtful and can find humor in his own unusual hobbies. He is described as incredibly persistent, with his determination and refusal to give up being his most notable qualities. Academically, he is often labeled a "muscle-head" and has a notable lack of skill in English, as well as a terrible sense of direction and fashion.

His primary motivation is to protect his own chastity and that of his beloved younger sister, Asane, whom he affectionately calls Asa-chan. To achieve this, he founds and leads a secret resistance group called NLNS (No Love No Sex), with the explicit goal of destroying the Pervert Ordinance. However, his motivations run deeper than simple idealism. His hatred for the island's promiscuous culture and its non-virgin citizens is rooted in childhood trauma. He was bullied as a child for the size of his genitalia, and a woman who defended him, the mother of a girl named Fumino Kotoyose, was later persecuted to death by the islanders for her work in the underground sex industry. Consequently, his quest is at least partially fueled by a desire for revenge against the society that caused him and his loved ones pain.

In the story, Junnosuke’s role is the driving force behind the anti-ordinance faction. After discovering a secret underground base, he is guided by a mysterious old man who informs him that finding a girl named Fumino Kotoyose is the key to destroying the law. This sets him on his path to rally others to his cause. He is noted for his terrible fighting aptitude in official tests, but his ability to make snap judgments in the field is above average.

Key relationships heavily influence his journey. His bond with his sister Asane is extremely close; they consider themselves as "two people who form a single brother" and often collaborate, with Junnosuke handling the hardware and Asane providing support in planning. Nanase Katagiri is a key companion in the resistance, and it is revealed that she was the girl who consoled him in the forest during his childhood, a memory he initially does not recall. Fumino Kotoyose is the girl he is destined to find, and he feels a strong sense of déjà vu upon meeting her because her mother was the one who helped him years ago. His relationship with Rei Tadasugawa, an agent of the Special Security (SS) force that enforces the ordinance, is complex; he develops conflicted feelings towards her and her comrades after realizing they are not inherently evil people. Tōka Reizeiin is another significant figure who helps him understand that his true enemy is not non-virgins, but the islanders who used the law to harm the people he cared about.

Junnosuke also undergoes development over the course of the narrative. In some routes, the revelation that his motivation is rooted in vengeance rather than pure ideology forces him to re-evaluate his cause, ultimately choosing to fight for his companions and ideals instead. He also confronts his own deep-seated sexual trauma. Due to his childhood experiences, he suffers from a form of impotence that prevents him from getting an erection with real women except in perfectly controlled, planned environments. His own anatomy is a source of deep personal complex, as his genitals become unusually large upon full erection, a trait he views as a weapon and a reason to avoid sex.

Junnosuke possesses several notable abilities. Despite being a "muscle-head" in academics, he is a talented inventor and creator, highly skilled at using a 3D printer and modeling software to craft elaborate artificial masturbators, which he considers works of art. He is also physically fit due to his daily strength training, and in some story routes, he receives training that drastically improves his combat skills, allowing him to become an effective front-line fighter. He occasionally uses a weapon modeled after an anal vibrator named Tsuranukimaru during NLNS operations. His primary tools for non-combat situations are his T-A-E devices, which he names like famous artworks, and he always carries a portable one called Haki-maru on his person.
