"ここからはじまるプロローグ。 (Kanon Remix)" is a remix of ああああ's original maimai composition, reimagined by arranger 大国奏音 (credited in the title as Kanon). The track was released on July 7, 2023, as part of the maimai 10th Anniversary Original CD, alongside two other remixes: "モ°ルモ°ル (MZK Skippin' Remix)" and "VERTeX (rintaro soma deconstructed remix)." At 190 BPM, the remix takes the melodic foundation of the original "Prologue That Begins Here" and injects it with Kanon's signature production style, resulting in a high-energy arrangement suited for the maimai DX FESTiVAL PLUS era. The song was unlocked through the 10th Anniversary Area 2 (10周年記念ちほー2), tying it directly to the game's milestone celebration. The jacket art features a composition drawn from a cutscene in the original song's music video, specifically the confrontation with a dragon, and incorporates the song logo of "封焔の135秒" (135 Seconds of Sealed Flame) into its design, creating a layered visual reference for longtime players.
