All songs

Overview

Cyaegha is a high-energy instrumental track by USAO (Masaharu Kubota), originally produced for lowiro's mobile rhythm game Arcaea as part of the paid "Absolute Reason" song pack. It crossed into SEGA's maimai でらっくす Splash on January 8, 2021, headlining the Arcaea Area collaboration event. Running at a relentless BPM of 200, the track showcases USAO's signature blend of hard-kick percussion, distorted synth leads, and pounding speedcore-tinged production, all without a single vocal line. The song's name comes from the Cthulhu Mythos: Cyaegha is one of the Great Old Ones in H.P. Lovecraft's fiction, a naming theme USAO carried across multiple rhythm-game compositions including "Hastur" (REFLEC BEAT VOLZZA) and "Cthugha" (Muse Dash). In maimai, Cyaegha received four DX charts. The MASTER difficulty, laid out by 隅田川星人 (Sumidagawa Seijin), sits at level 13+ with a constant of 13.8, a demanding arrangement that originally held a level 13 rating before being bumped up in the FESTiVAL era. The EXPERT chart, designed by シチミヘルツ (Shichimi Hertz), tests players at level 11 with prominent slide-note sequences threading through the song's dense instrumental breaks. Beyond maimai, Cyaegha appears in CHUNITHM and ONGEKI, reflecting the track's reach across SEGA's rhythm-game ecosystem. An Extended Mix and a remix by fellow composer Laur were later released on USAO's album XTREME, giving fans alternate takes on the track's relentless energy.

Trivia

Cyaegha originates from lowiro's mobile rhythm game Arcaea, where it was released as part of the paid song pack "Absolute Reason."
The title references Cyaegha, a Great Old One from H.P. Lovecraft's Cthulhu Mythos. It forms a thematic trio with two other USAO rhythm-game tracks, "Hastur" (REFLEC BEAT VOLZZA) and "Cthugha" (Muse Dash), all named after Mythos entities.
In maimai でらっくす Splash, Cyaegha was initially exclusive to the Arcaea Area collaboration event from January 8 to March 3, 2021, requiring 58 km of total distance to unlock. It became freely available to all players on March 4, 2021.
The MASTER chart, designed by 隅田川星人 (Sumidagawa Seijin), was originally rated level 13 from Splash through UNiVERSE+, then upgraded to level 13+ starting with FESTiVAL, reflecting the chart's enduring challenge as the game's difficulty scale evolved.
An Extended Mix of Cyaegha and a remix by fellow composer Laur both appear on USAO's album XTREME.
Cyaegha is purely instrumental, with no lyrics or vocal samples. Its impact relies entirely on USAO's hardcore production style.
The song also appears in CHUNITHM (starting from PARADISE) and ONGEKI (bright MEMORY onward), with dedicated charts in each game, making it one of the more widely circulated Arcaea crossover tracks across SEGA's rhythm-game lineup.
In the Chinese version of maimai (舞萌DX), Cyaegha became unlockable later, on April 8, 2022 in 舞萌DX 2021, requiring 200 m of distance in the corresponding Area.
