パラボラ (Parabola) is an original maimai track composed by *Luna, a Vocaloid producer and the founder of the doujin circle BASYAUMA RECORDS. It features vocalist NORISTRY on the mic, marking NORISTRY's second appearance in the maimai series after their debut on "居並ぶ穀物と溜息まじりの運送屋." The song debuted in maimai でらっくす Splash on December 11, 2020, as a Perfect Challenge reward in the Sky Street Area (スカイストリートちほー), appearing after accumulating a total distance of 280 km. It was the first Perfect Challenge track to carry a level 13+ MASTER chart, making it a notable milestone for the event system. At 192 BPM, the song delivers an energetic, driving pop-rock sound built around a bright melody and soaring chorus about determination, individuality, and chasing the future, themes reflected in its title, which references a parabola (放物線). The accompanying flavor text tells a standalone narrative about Sō, a gifted high-school basketball prodigy who time-leaps after receiving a mysterious message, only to be attacked by a figure named Noah and stranded in his childhood body. The music video was produced by the creative group 群青リコリス (Gunjou licorice). The MASTER chart, designed by シチミヘルツ (Shichimi Hertz), features 963 notes with dense slide patterns and heavy use of Touch notes, earning its 13.8 difficulty constant. The EXPERT chart (level 11.2) was designed by はっぴー (Happy). Notably, the BASIC chart was originally level 5 at launch but was lowered to level 3 starting from the UNiVERSE PLUS update, reflecting a re-evaluation of the easier difficulty. The song is available across all regions (Japan, International, USA, China) and became unlockable by default from maimai DX UNiVERSE onward.
