"新人類" (Shin Jinrui, "New Humanity") is a Vocaloid track that brings together three heavyweight figures from Japan's online music scene: pianist and utaite まらしぃ (marasy), Jin (the architect of the Kagerou Project multimedia franchise), and 堀江晶太 (Shouta Horie, also known as kemu), featuring the voice of Kagamine Rin. Released as a single and album in 2023, the song arrived in maimai DX BUDDiES PLUS on May 24, 2024, and later crossed over into CHUNITHM VERSE in early 2025. Lyrically and thematically, "新人類" is a sardonic commentary on modern convenience and the perceived devolution of humanity. The chorus erupts into primate-like chanting, "ウッホウッホッホ" (ooh-ooh-ooh), as the lyrics playfully suggest abandoning the trappings of civilization, social media noise, and intellectual pretense to embrace a more primitive, carefree existence. The title itself ("new humanity") is delivered with heavy irony: the "new humanity" the song describes is one gleefully regressing, not advancing. For maimai players, the track is notable for its chart spread. The Master difficulty (level 13+, constant 13.6) was designed by Luxizhel and packs 1,056 notes into a 2:32 runtime, with a staggering 896 Tap notes, one of the most tap-heavy distributions at this level, demanding crisp fingerwork and endurance. The Expert chart (level 10+, constant 10.6) was designed by はっぴー (Happy) and features 612 notes with a balanced mix of Touch, Slide, and Hold patterns. Both creators brought distinct charting philosophies to the song's energetic, piano-driven instrumental and call-and-response vocal structure.
