Restricted Access is an instrumental electronic track by the composer and producer Knighthood, originally created for the mobile rhythm game *Paradigm: Reboot*. It joined the maimai DX song library as part of the CiRCLE edition, rolling out regionally through early 2026, arriving in Asian territories at the edition's launch, in Japanese arcades on January 23, 2026, and in Chinese cabinets running 舞萌DX 2025 on February 10, 2026. The title and musical motifs position Restricted Access as a direct thematic sequel to Knighthood's earlier composition "Access Denied" from *Orzmic*, creating a two-part narrative across separate rhythm-game titles. Running at a brisk 185 BPM over 2 minutes and 33 seconds, the track delivers crisp, driving electronic production with no vocals, a purely instrumental piece built for gameplay impact. The accompanying music video was produced by TunerGames. In maimai, Restricted Access spans four DX-format charts. The Expert chart (level 11) was designed by アマリリス (amaryllis), while the Master chart (level 13.8) was handled by Luxizhel. The Master chart in particular stands out for its heavy Touch-note count, 165 out of 920 total notes, making extensive use of the DX cabinet's touch sensors alongside dense Tap and Slide patterns.
