Bloody Trail is an instrumental maimai original track by Hommarju (Masaya Nakamura), a veteran composer best known for his contributions to Konami's BEMANI series, including beatmania IIDX and jubeat. Commissioned directly for maimai でらっくす BUDDiES PLUS, the song arrived on May 10, 2024 as the centerpiece of the Metropolis Area 8 Perfect Challenge event. Running at a relentless 195 BPM, Bloody Trail delivers exactly the kind of hard-edged, synth-driven energy Hommarju's fans expect: pounding kicks, aggressive basslines, and rapidly shifting melodic leads that keep the tension high throughout its 2:27 runtime. The track is purely instrumental, no lyrics, letting the composition speak entirely through its rhythmic momentum and harmonic structure. A remixed extended version, titled Zusammenbruch of Bloody Trail (Zusammenbruch being German for "collapse"), was included on Hommarju's single released June 8, 2024, and later appeared on the maimai でらっくす ベストアルバムちほー3 soundtrack. The song is thematically tied to the Metropolis Area story arc. Its in-game flavor text describes a world overtaken by a petrification disease and environmental collapse, with humanity abandoning Earth for space. Against this backdrop, the characters Juuyako and Saiki propose remaining on the ruined planet to build a self-sustaining city, Metropolis, and create immortal residents capable of continuing purification research. Bloody Trail's aggressive, driving sound mirrors this narrative urgency. The video production was handled by an artist credited as サム (Sam), giving the track a distinctive visual identity. In terms of chart design, the MASTER difficulty (level 14, constant 14.5) was crafted by 翠楼屋 (Suirouya), while the EXPERT chart (level 12+, constant 12.8) was designed by 鳩ホルダー (Hato holder). The MASTER chart in particular stands out for its extremely low Touch note count, just 3 across 1,156 total notes, making it an anomaly among modern DX charts at this difficulty level.
