Overview
Overjoy ★ OVERDOSE!! is a BMS (Be-Music Source) contest track originally submitted to THE BMS OF FIGHTERS : NT -Twinkle Dream Traveler- (BOF:NT), where it placed 11th overall. The song was later added to maimai でらっくす PRiSM PLUS on April 11, 2025, as part of the GAME & VARIETY (ゲーム＆バラエティ) genre category, joining a long tradition of BMS-origin tracks featured in Sega's rhythm game series.
The track is credited to Luna Fozer, a fictional multi-cultural BMS VTuber persona, brought to life by a supergroup of established rhythm-game composers: BilliumMoto, Kurokotei (黒皇帝), and Sobrem. The vocals are performed by vally.exe, with lyrics penned by AKA. The song's music video was produced by riguruma, featuring character art by Shalink and a character named 蟹江 (Kanie). Thematically, Luna Fozer's lyrics weave a playful, self-aware narrative about being a VTuber streamer, directly addressing the audience, name-checking past BMS community touchstones, and even poking fun at how BMS songs end up categorized under "VARIETY" or "GAME & VARIETY" in Sega's rhythm game genre taxonomy.
In maimai, Overjoy ★ OVERDOSE!! spans four DX difficulties. The Expert chart was designed by サファ太 (Safata), while the 14.2-level Master chart, carrying 1074 total notes, was crafted by Jack, a high-density arrangement that matches the song's energetic, self-referential BMS-celebratory mood.
