Soteria (ソテリア) is an original song made for maimai でらっくす CiRCLE PLUS, arriving on March 19, 2026 as part of the Tricolor Area 2 (トリコロちほー2) event series, a content update following the BUDDiES era. Composed, arranged, and written by Rafutsuri with vocals by 桜あおい (Aoi Sakura), the track is gated behind a Perfect Challenge that demands 700 km of accumulated distance within the area, giving it a sense of earned discovery for dedicated players. The title ソテリア transliterates Soteria (Σωτηρία), the ancient Greek spirit of deliverance, safety, and preservation from harm, a fitting name for a song whose lyrics dwell on the impossibility of holding onto someone who now exists only in photographs. The flavor text displayed in-game reinforces this mood: vivid memories that refuse to fade, a person reduced to a single small image. The accompanying music video (movie) was produced by 檀上大空, complementing the melancholic yet driving 160 BPM arrangement. For players tackling its charts, Soteria offers a Master chart at level 14 (difficulty constant 14.1) designed by サファ太 (Safata) and an Expert chart at level 12 (constant 12.0) by シチミヘルツ (Shichimi hertz). The lower difficulties, Basic and Advanced, do not have named designers listed. As a Japan-exclusive CiRCLE PLUS original with no appearances in other music games, Soteria remains a track tied intimately to this particular maimai update.
