Overview
LOSTPHANTASIA is a Touhou Project arrangement collaboration that brings together two prominent acts in the Japanese doujin and anime music scene: 岸田教団&THE明星ロケッツ and composer/pianist 草野華余子 (Kayoko Kusano). Originally created as the main theme for the rhythm game Touhou Danmaku Kagura Phantasia Lost (東方ダンマクカグラ ファンタジア・ロスト), the track stitches together melodies from three iconic 東方永夜抄 (Imperishable Night) compositions, 少女綺想曲 ～Dream Battle (Reimu's theme), 恋色マスタースパーク (Marisa's bomb spell theme), and 永夜の報い ～Imperishable Night (Stage 4 theme), into a cohesive, melancholic rock arrangement.
The track's production credits reveal a fully featured live band: vocals are split between ichigo (of 岸田教団&THE明星ロケッツ) and Kusano herself, with guitarist Hayapi~, bassist/lyricist Kisida, and drummer micchan rounding out the ensemble. Kusano also handles piano and overall arrangement. At 133 BPM and just over two minutes long, LOSTPHANTASIA sits at a moderate tempo that lets its lyrical themes of lost dreams, mirages, and fading fantasy take center stage.
In maimai DX, LOSTPHANTASIA arrived as part of the BUDDiES PLUS update (June 2024 for Japan, October 2024 internationally, and September 2025 in China under the 舞萌DX 2025 cabinet revision). Notably, before the PRiSM version, the song credit listed only 岸田教団&THE明星ロケッツ, with Kusano's involvement added in a later update. Its Master chart, designed by サファ太 (Safata) at a difficulty constant of 12.6, is the standout offering, while the Expert chart (9.6) was crafted by 鳩ホルダー (Hato Holder).

Trivia
- LOSTPHANTASIA serves as the main theme of the rhythm game Touhou Danmaku Kagura Phantasia Lost (東方ダンマクカグラ ファンタジア・ロスト), a spin-off of the Touhou Project danmaku franchise.
- The song is a medley-like arrangement drawing from three distinct tracks in Touhou 永夜抄 ～ Imperishable Night: 少女綺想曲 ～Dream Battle (Reimu Hakurei's theme), 恋色マスタースパーク (Marisa Kirisame's boss spell theme), and 永夜の報い ～Imperishable Night (Stage 4 field theme).
- Composition credits trace back to ZUN (Team Shanghai Alice), the creator of the Touhou Project, whose original melodies form the foundation of this arrangement.
- The arrangement and piano parts were handled by Kayoko Kusano (草野華余子), while lyrics and bass were contributed by Kisida of 岸田教団&THE明星ロケッツ.
- Vocal duties are shared between ichigo (the regular vocalist of 岸田教団&THE明星ロケッツ) and Kayoko Kusano, giving the song a dual-vocal dynamic.
- Guitar work comes from both Hayapi~ and Kisida, with drumming by micchan, a full live-band recording rather than a purely synthesized production.
- Before the PRiSM version of maimai DX, LOSTPHANTASIA was credited simply to 岸田教団&THE明星ロケッツ, omitting Kayoko Kusano's name. The ×草野華余子 suffix was added in a later attribution update.
- LOSTPHANTASIA was added to the Japanese version of maimai DX BUDDiES PLUS on June 7, 2024. The Asian (international) version received it on October 4, 2024, and the Chinese version on September 24, 2025 as part of 舞萌DX 2025.
- The song's Japanese lyrics center on themes of lost dreams, collapsing illusions, and a search for mirages, fitting the 'LOSTPHANTASIA' title that blends 'lost' with 'phantasia' (fantasia/fantasy).
- At 2:07 in length, LOSTPHANTASIA is a relatively concise arrangement typical of arcade rhythm game inclusions, condensing its three-source-song medley into a tight playable format.
