After repeatedly failing to keep a part-time job, a young man is hired at the Freedom Manga Cafe. His first day takes an erotic turn when he reunites with the now-mature daughter of the owner and is trained by a seductive senior employee, leading him to discover that his new workplace is far more stimulating than he ever imagined.
While working at the manga cafe, Keiichi encounters the famous idol Mitsuki Otona. After a clumsy accident leads to an intimate conversation, Mitsuki is drawn to Keiichi's unique "lucky pervert" nature and his ability to treat her like a normal person. This spark ignites a passionate group encounter with his co-workers, which surprisingly helps dampen the chaotic effects of Keiichi's aura.
Keiichi's life at the manga cafe is thrown into chaos when a rival chain, Net Cafe Medium, opens nearby and begins stealing their customers. The ruthless CEO, Midou Sayaka, seeks revenge against Keiichi following an embarrassing encounter, vowing to drive his shop out of business. Amidst the stress of the business war, Keiichi finds comfort in intimate encounters with the women in his life, even as he fears the impending closure of the cafe.
The team visits a luxurious net cafe owned by the Midou group, where they are mocked by a haughty manager who claims her establishment is far superior to Comic Cafe Freedom. However, through a strange "happening" power, they discover the manager's hidden, lewd desires. Amidst chaotic sexual encounters, the group manages to secure the future of their own cafe, ensuring their adventurous days continue.
