Maboroshi is a high-energy electronic track by Japanese producer Camellia (かめりあ, under his EDP alias), originally composed for Rayark's mobile rhythm game Cytus II. It joined the maimai song library on June 11, 2020, as part of the maimai でらっくす PLUS (DX PLUS) update through a collaboration between Sega and the Cytus franchise. At a driving 190 BPM, the song delivers the dense, intricately layered production style Camellia is known for, rapid percussion, aggressive synth leads, and rhythmic complexity that carries into its in-game charts. The version featured in maimai is a shortened edit of the full Cytus II original. The song's title carries an unusual backstory: it is the romanized reading of an obscure inverted kanji character, the standard character 予 (yo, meaning "I" or "beforehand") rotated 180 degrees (𠄔), which is traditionally read as "maboroshi" (まぼろし, meaning "illusion" or "phantasm"). Because the character could not be rendered correctly in the maimai game client, the title was converted to its romaji form for display. The jacket artwork preserves the original character in its proper orientation. In-game, Maboroshi is categorized under ゲーム＆バラエティ (Game & Variety). Its MASTER chart, designed by 華火職人 (Kanon Oguni), is rated level 14 (constant 14.2) and packs 944 notes, notably including 126 Touch notes, one of the highest Touch-note counts among DX PLUS charts, making extensive use of the cabinet's sensor panel. The EXPERT chart, designed by サファ太 (Safata), sits at level 11. Both lower difficulties (Basic and Advanced) carry the standard auto-assigned layout. Regionally, the song launched in Japanese, international, and USA cabinets on day one, with the Asian version following in November 2020 and the Chinese version (舞萌DX) arriving in May 2021 before being removed starting with 舞萌DX 2022.
