Third-generation VTuber Awayuki Kokorone's fans know her as a prim, proper, and graceful idol. Though she has considerably less fans compared to other VTubers in the Live-On agency, Awayuki's loyal following supports her every step of the way. One night, Awayuki forgets to turn her livestream off—a blunder that changes the trajectory of her online career forever. Contrary to her usual angelic persona, her genuine brutish personality is exposed to more than ten thousand people who tuned in. Awayuki reveals that she is nothing more than a severe alcoholic who spouts profanities nonstop, constantly viewing her fellow VTubers with lustful admiration. However, instead of being reprimanded by her agency, Awayuki receives praise: her unhinged, disorderly conduct was Live-On's actual expectation of her. Now having her big break and permission to stream without holding anything back, the once-unpopular VTuber begins her rise to stardom.

Constantly on the run from loan sharks, Hime Arikawa has to deal with the debt left over from his parents' lousy spending habits, which they left under his name. Fleeing in a maid outfit forced upon him by the moneylenders, he is found and rescued by Shimoshina High School's student council, who pay the debt in full. However, now indebted to the student council for saving him, they not only make Hime transfer schools, but also make him a part of the student council as their servant! Forced to cross-dress for the rest of his high school years, Hime has no other option but to obey the demands of the girls in the student council. As he is harassed both mentally and physically, he must overcome his somewhat perverted classmates and join forces with other crossdressers throughout the school.

Having completed their Stagiaire assignments, the residents of Polar Star Dormitory and their friends visit a hot springs inn. Though they planned on relaxing, these young chefs step up to the plate when the inn's entire kitchen staff suffer accidents. Unbeknownst to them, they will not be cooking for any ordinary patrons. Sometime after this trip, Souma Yukihira's desire for worthy opponents is stoked when he, Megumi Tadokoro, and the other Autumn Election quarter-finalists are invited to the annual Autumn Leaves Viewing event. The eight Tootsuki freshmen have a special opportunity to enjoy tea with the Elite Ten Council—including the Tenth Seat Erina Nakiri, who participates alongside her first-year classmates. Though it is framed as a friendly introduction between nine promising underclassmen and nine prestigious upperclassmen, Director Senzaemon Nakiri sees this meeting for what it is: a first encounter between the current reigning elite and their eventual usurpers.
