不機嫌なスリーカード (Fukigen na Three Card, roughly "Sulking Three Card") is an original song by the VTuber musical unit HIMEHINA that joined the maimai DX song library during the FESTiVAL PLUS update. It was first made available on March 23, 2023, through the dedicated HIMEHINA area (ヒメヒナちほー), before becoming generally unlockable on May 12 of the same year. The song sits in the POPS＆アニメ genre at a brisk BPM of 195, giving it a high-energy pulse that carries through its charts. The title evokes a card-game metaphor, "three of a kind" in poker terminology, reinforced by in-game collectible title rewards that reference betting one's life and playing multiple HIMEHINA songs in a single credit. The Expert chart was designed by 翠楼屋 (Suirōya), while the Master chart was crafted by アマリリス (Amaryllis). The Master chart originally debuted at level 12+ during FESTiVAL PLUS through the BUDDiES version, then received a level bump to 13 starting with BUDDiES+, reflecting both player skill growth and the chart's mechanical demands at 559 total notes with a healthy mix of Slide and Break patterns. An utage (宴) chart bearing the unusual difficulty marker "蛸/13?" was added on November 22, 2024, expanding the song's replay value with a denser 693-note arrangement.
