Overview
アウターサイエンス (Outer Science) is a Vocaloid track by Japanese musician and novelist Jin (じん), serving as the final narrative entry in his expansive Kagerou Project (カゲロウプロジェクト) multimedia series. The song features vocals from the IA Vocaloid voicebank, with arrangement by Nhato (Tatsuya Fukumuro), a producer known for his electro-house and dubstep-influenced style, and an official music video animated by Sidu. Originally released on the 2013 album メカクシティレコーズ (Mekaku City Records), the track made its rhythm-game debut in CHUNITHM AIR in 2016 before arriving in maimai MiLK on June 5, 2018. Its lyrics unfold a dark, grotesque allegory about consumption, rebirth, and cyclical fate, themes that tie directly into the Kagerou Project's overarching narrative about characters trapped in an endless loop of death and resurrection. The song's intense 195 BPM drive and brooding, theatrical arrangement made it an immediate fit for challenging charts: in maimai, the Expert chart (designed by Jack) and Master chart (designed by はっぴー) both sit at high difficulty levels, demanding precise hand coordination through dense note streams and sweeping slide patterns. In Asian English releases, the title is romanized as Outer Science.
