"Fraq" is the theme song of maimai でらっくす PRiSM PLUS, composed and arranged by Kennosuke Ono under his owl＊tree alias with vocals by べんざ (Benza). The track features live piano and brass performed by Osamu Kubota, with mixing by Leiki Ueda and a music video by aco (illustrated by やみや). At 221 BPM, it ranks among the faster original compositions in the maimai catalog, delivering an energetic electronic arrangement punctuated by brassy fanfares and driving percussion. Lyrically, Fraq captures the atmosphere of an arcade rhythm game community, players filtering out surrounding noise, calming their heartbeat to take aim, throwing in coins to enter, and pushing through the "gauntlet" of challenging songs. The recurring flag motif (旗) directly references maimai's clear flags, while verses about familiar faces and unspoken bonds echo the game's Seven-colored Area flavor text, which describes the quiet camaraderie that develops between regular players who compete side by side in the same rotation, wondering who will claim the clear flag first. The song debuted on March 13, 2025, initially locked behind the Seven-colored Area (なないろちほー) where players needed to accumulate 30 km of distance to unlock it. From the subsequent CiRCLE PLUS update onward, it became available by default to all players. The title "Fraq" suggests a fusion of "fragment" and "frequency," and the track's relentless momentum mirrors the escalating intensity of high-level maimai play. Fraq also notably marks the only owl＊tree collaboration where the featured artist's name lacks the "＊tree" suffix in the official credits.
