Technicians High is an original maimai composition by HiTECH NINJA, the alias of MEGAREX-affiliated producer lapix. It debuted in the Metropolis Area (メトロポリスちほー) event, which ran from August 9, 2019 through September 16, 2020, where players unlocked it by reaching 120 meters of area progress. The track marked HiTECH NINJA's second contribution to the maimai series following Hyper Active, and it later appeared in CHUNITHM NEW as part of the ゲキマイ cross-series catalog. The song itself is a driving, high-energy electronic instrumental clocking in at 165 BPM with no vocal track, pure synth and percussion designed for arcade rhythm-game intensity. Its DX Master chart, designed by 華火職人 (Kanon Oguni), is defined by an infamous 16th-note touch-note barrage that begins approximately 15 seconds in, which the community calls the "blue wall" (青い壁). The pattern runs in sections of 4, 6, 4, and 3 touch notes, with touch inputs entering from the upper-left when started with the left hand. With 147 Touch notes out of 870 total on the DX Master chart, the wall accounts for a substantial portion of the chart's challenge. Technicians High holds a unique place in maimai's chart history: it was the first song in the series to debut with DX (でらっくす-style) charts and later receive Standard (STANDARD-style) charts as post-release content. Its Standard charts arrived on November 12, 2021 as a reward in Friend Matching Season 2, and the Standard Master chart, designed by シチミヘルツ (Shichimi Hertz), reimagines the blue wall as a Tap-stair and Each-note pattern instead of touch notes, offering a distinctly different play feel from its DX counterpart.
