QZKago Requiem is an original composition by t+pazolite (Tomoyuki Hamada) that debuted in maimai FiNALE on December 18, 2018 as the opening salvo of the PANDORA BOXXX event series, Stage 1 Phase 1, representing the maimai GreeN era. The track runs at a blistering 257 BPM and was created as the direct sequel to t+pazolite's earlier maimai contribution, Garakuta Doll Play (maimai GreeN, 2013). Several vocal samples and motif callbacks from the predecessor are woven into the track, though the iconic "Bulgaria" sample from the original does not make a return. The song is accompanied by an animated music video (the only PANDORA BOXXX song to receive one) created by illustrator and animator 百舌谷 (Mozuya). The video features the returning characters Shama and Milk, whose iconography also appears on the jacket and in unlockable in-game nameplates and frames. Midway through the video, the画面 glitches into a distorted, blue-tinted sequence that mirrors the chaotic energy of the track's second half, a visual flourish that carries over into t+pazolite's own live performances, where he is known to swap the video to a bluescreen and cut to a different track mid-play. A prototype version titled "QZKago Requiem (Rehearsal)" was secretly included on the maimai × t+pazolite special CD "Garakuta Scramble!", and an extended "Uncut Edition" later appeared on t+pazolite's album ハートエイク・デバッグ (Heartache Debug). The game-length version is also collected on the "PANDORA BOXXX PLUS" and "maimai ALL PERFECT COLLECTiON" releases. Beyond maimai, the song has been ported to CHUNITHM NEW PLUS, オンゲキ R.E.D. PLUS, and the mobile rhythm game Phigros.
