"Final Step!" is an instrumental crossover track by the composer Lime, originally featured in the rhythm game Muse Dash and later brought to maimai でらっくす FESTiVAL PLUS as part of a limited-time collaboration event. Running at a steady 180 BPM, the song sits in the ゲーム＆バラエティ (Game & Variety) genre and carries the energetic, synth-driven sound signature that Lime is known for across the rhythm-game scene. In maimai, "Final Step!" was unlockable during the Muse Dash Area event from April 14 to June 22, 2023, in the Japanese/International version, while the Chinese version saw it added later via 舞萌DX 2023. The song has no vocal track, its drive comes entirely from layered electronic instrumentation and a propulsive beat. The chart set spans from a Basic 4 up to a demanding Master 13+ (level constant 13.8), with the Expert chart laid out by Jack and the Master chart crafted by サファ太 (Safata), giving upper-tier players a dense, break-heavy 859-note endurance test.
