Allegro Con Fuoco

The track runs at 156 BPM and opens DM Ashura's Allegro series, later continued by Allegro Piu Mosso. Stylistically it sits close to the same composer's NeoMAX. Among the songs ported over from the Pro line, it was one of the most popular, alongside Gargoyle. A roughly four-and-a-half-minute full song exists; hearing it makes clear how cleanly the arcade cut was edited. The full song arrived in XX in April 2019, with one section after the intro using a slightly different tone from the original. In Fiesta EX the BGA received tweaks, such as a shot of fluttering sheet music turned to slow motion and changed camera angles on the music stand.

S5 is tougher than expected for a beginner chart, with level 5-6 stretches early and mid-song; it rose to S5 in PHOENIX and left Basic mode. S7 is built on 8-beat notes with essentially no twists. S10 (formerly 11) is startlingly easy for its number and dropped to 10 in XX. S17 has mild twists but few rest points, with runs that lengthen toward the end. S22 is the D23 folded into Single: it opens with twist runs and barely lets up until the finale unleashes twist runs laced with short 32-beat bursts, plus a few 24-beat passages at the very end.

In Double, D11 (formerly 9) and D18 are spreads of the Single charts, with D18 a stamina test built on trills and 2-notes. D23 ranks among the harder charts at its level: its opening "crab-leg" run and its final 32-beat run were so influential that runs with 32-beat bursts came to be nicknamed "Allegro." The Full Song adds a stamina-heavy S23 and D25, plus a widely praised D21 charted by NIMGO. The Quest Zone offers a D27 titled "Good bye Nimgo," packed with gimmicks, special notes, and speed changes, which drew divided reactions.
