Kazuki Yamada, an 18-year-old university student in Tokyo, is determined to leave his painful past behind. Orphaned by a tragic accident and mistreated by his cruel relatives, Kazuki’s life has been a series of unfortunate events. Now, at the prestigious Tokyo University, he hopes to reinvent himself and escape his troubled history. However, his first day of university takes a dramatic turn when he heroically helps an elderly woman cross the street, only to be struck by a car in the process. When Kazuki wakes up in the hospital, he is not only nursing physical injuries but also an unexpected new reality. He has activated a mysterious system with a loli-voiced AI that demands he complete increasingly perverted tasks to survive. From stealing panties to peeking on unsuspecting girls, Kazuki must navigate this bizarre, often humiliating system while trying to maintain a semblance of normalcy. The system's rewards—new skills, experience points, and, ultimately, the means to stay alive—are tied to his interactions with beautiful women. As Kazuki fumbles through his new life, working part-time at a convenience store and dealing with his classmates, he encounters a colorful cast of characters, including Haruka Takahashi, a friendly but popular girl, and Rina Yoshida, a quiet and enigmatic student. Alongside these initial characters, he faces challenges from local gangsters and intriguing mature women. As Kazuki’s perversion deepens and his interactions grow more intimate, the stakes of his tasks escalate.
