Overview

終わりなき物語 (OWARINAKI MONOGATARI) is a Japanese-style rock track that originated inside Sega's long-running MMORPG PHANTASY STAR ONLINE 2. Within PSO2, the song is performed by the NPC singer Quna (voiced by Eri Kitamura) during in-game stage live concerts. It was added to the game on September 10, 2014, marking Quna's third stage-live performance piece and establishing a recurring role for the character as an in-universe idol-like figure. The music was composed by Mitsuharu Fukuyama with lyrics by mavie, and the full version appears on the album PHANTASY STAR ONLINE 2 Original Sound Tracks Vol.3, released in 2013. 終わりなき物語 crossed into rhythm-game territory when it debuted in maimai PiNK PLUS on November 4, 2016, under the GAME & VARIETY (ゲーム&バラエティ) genre. Its Master chart was crafted by Jack, a prolific notes designer whose contributions span multiple maimai generations, while the Expert chart was designed by ロシェ@ペンギン (Rocher@penguin). The song later appeared in CHUNITHM STAR as part of a limited-time PHANTASY STAR ONLINE 2 collaboration MAP event, broadening its reach beyond the maimai arcade ecosystem. In Asian English versions of maimai, the track is listed under the romanized title OWARINAKIMONOGATARI, keeping the original pronunciation accessible to international players.
