Originally created for SEGA's Tokyo Joypolis digital-real attraction HALFPIPE TOKYO, Link is a techno-pop track by Clean Tears featuring vocalist Youna. The song made its maimai debut in maimai PLUS on March 14, 2013, and carries the distinction of being one of the earliest original songs commissioned for the series from an external attraction collaboration. Musically, Link is a light, upbeat techno number driven by a bouncing rhythm and heavy distorted synthesizer lines. Youna's transparent, floating vocal delivery contrasts with the aggressive synth work, giving the track a distinctly pop edge. The accompanying PV, created by yama-ko, depicts a starry-night atmosphere that reinforces the song's cosmic lyrical theme, lyrics by Aki Sato explore two souls linking across the night sky, weaving imagery of shooting stars and cosmic lovers. Composer Clean Tears is a well-known Vocaloid producer (Vocaloid P) who first gained traction on niconico douga. His debut upload, "水鏡の庭" (Mizukagami no Niwa), is regarded as a pioneering work of the "Miku-trance" boom. Beyond his original Vocaloid compositions, he has produced Touhou arrangements, instrumental works, and is an active member of the doujin circle はちみつれもん (Hachimitsu Lemon). This collaboration with Youna (vocals) and Aki Sato (lyrics) grew out of his existing working relationship with both artists. In maimai, Link has an unusual chart history: during maimai DX PLUS, its EXPERT chart (level 11) was briefly rated higher than its MASTER chart (level 10+), a rarity in the series. The song later received a Re:MASTER chart in maimai DX BUDDiES (November 2023), designed by じゃこレモン (Jako Lemon), with a dense 475-note layout that stands as the most demanding version of the track.
