New talent VTuber Hoshizora Baado is an online sensation whose avatar presents her as a cute high school girl. The apparent high schooler, however, constantly lets slip dated references, old-timey slang, and retro cultural knowledge that betray a much older and more experienced generation. This age fraud is so obvious that her viewers spend every stream playfully trying to determine her real senior status, turning the gap between her youthful appearance and her senior’s sensibilities into the central joke of her channel.

Baado’s streams—from cooking broadcasts in gloves that hide elderly skin to nostalgic rants about decades-old TV shows—consistently entertain her audience, who know they are watching someone clearly faking their birth year. As her popularity grows, she befriends fellow VTuber Kakihara Meisu, whose mother also gets drawn into VTuber activities. Baado’s social circle expands to include the “Curve Editor” crew, leading to collaborative streams and the high-stakes organization of Meisu’s first solo live concert, which suffers a technical crisis until an unexpected helper steps in.

Later volumes broaden the scope further. When Baado goes on a trip, her eccentric friends hijack her channel, causing chaotic streams that lead to account restrictions. A new storyline introduces a band called Hoshizora Band, whose lineup includes Baado’s original artist, a real-life friend, and a talk-show VTuber, plus a surprise vocalist. The fourth volume includes a substantial flashback arc: Baado returns to her childhood elementary school before it closes, walking through the empty hallways and remembering her past, eventually meeting a mysterious entity she calls a “god” in the old school building.

Throughout the series, the comedy hinges on the contrast between Baado’s digitally youthful VTuber image and her unmistakably old-school tastes, while the narrative steadily builds a warm community of creators around her, blending retro humor with the modern VTuber culture.
