Ether Strike is a high-energy electronic track by Akira Complex, originally composed for lowiro's mobile rhythm game Arcaea and later brought to maimai as a crossover addition during the Splash season. Released on January 8, 2021, it sits in the GAME & VARIETY (ゲーム＆バラエティ) category and drives forward at 156 BPM. Akira Complex, a producer affiliated with the Attack The Music label, wrote a piece defined by aggressive synthesizer leads and intricate rhythmic layering, qualities that translate directly into the maimai charting experience. The track is purely instrumental with no vocals, letting its dense electronic arrangement command attention from start to finish. In the maimai community, Ether Strike is best known for its Master chart, designed by シチミヘルツ at level 13+ (constant 13.9) with a dense 852-note count that demands equal competence across all note types. The Expert chart by 小鳥遊さん offers a 10+ alternative with a distinct design philosophy. The song's crossover origin from Arcaea, a game known for its challenging rhythm mechanics, gives it a natural place in maimai's repertoire of boss-level crossover content. A sequel track, Ether Second, would later appear in maimai DX BUDDiES, and an extended arrangement titled "Ether Strike ('Divine Mercy' Extended)" was released on the Arcaea Sound Collection: Memories of Light soundtrack. Regionally, the song reached Asian arcades on May 21, 2021 and Chinese cabinets on April 8, 2022.
