Hatsumi-chan is the unofficial mascot of Hatsuhoshi Academy in the mobile game Gakuen Idolmaster. She appears as a two-headed star-shaped figure with an “H” in one eye and a plus-sign gleam in the other. Officially she exists only as classroom graffiti, skill cards, and a few items, yet she became a breakout character through a series of short tutorial videos in which she explains produce mechanics with manic energy, sudden mood swings, and lines that feel more like threats than advice. Fans latched onto that contrast between cute design and unsettling delivery, turning her into a running joke and affectionately calling her a little devil long before any Halloween event existed.The current wave of posts is tied to a new in-game season that leans into exactly that image. A live broadcast the previous evening announced little-devil-themed gravure cards, a new song titled Agitato, a story event called “Watashi, Koakuma,” and related gacha banners. Promotional copy now frames the whole campaign as Hatsumi-chan luring producers into her classroom and then sending them off to meet the idols dressed as small demons. Players are quoting the campaign lines, posting the official key visual, and treating the mascot’s already-established chaotic personality as the perfect mascot for the theme.In short, an originally unofficial, slightly unhinged tutorial character has been officially embraced as the face of the game’s latest seasonal event, and the community is celebrating the moment by circulating the campaign phrasing that puts her at the center.
