Overview

BLUE ZONE is a high-energy collaboration track by Tatsh × NAOKI, two heavyweight figures from the Japanese rhythm-game and doujin music scenes. The song is a direct spiritual successor to their earlier collaboration "RED ZONE," which originally appeared in Konami's beatmania IIDX 11 IIDXRED. BLUE ZONE carries forward the aggressive electronic sound and motorsport-inspired imagery of its predecessor, punctuated by rapid-fire rap verses from Kent Alexander. The track was first introduced in SEGA's CHUNITHM NEW before arriving in maimai でらっくす UNiVERSE PLUS on April 28, 2022. A long version is included on TatshMusicCircle's album "Relation." In maimai, the song is categorized under GAME & VARIETY (ゲーム&バラエティ) and features DX charts across all four standard difficulties. The Master chart, designed by 隅田川星人 (Sumidagawa Seijin), clocks in at level 14 with a distinctive note total of 888, a number with auspicious connotations in East Asian culture. The Expert chart was designed by はっぴー (Happy).
