ツクヨミステップ (Tsukuyomi Step) pairs an ancient Shinto namesake with brisk 172 BPM electronic-pop. Its title invokes Tsukuyomi-no-Mikoto (月読命), the Shinto moon deity, but the music, by producer YURRY CANON (ユリイ・カノン) with vocals by nameless, is anything still or lunar. Instead, the track moves at a breathless clip, layering sharp synth leads and rapid-fire vocal delivery over a driving beat. The lyrics paint a scene of chasing a dream that dissolves upon waking, stumbling through a hollow world, and dancing with abandon under a false moon, a restless energy that matches the tempo. Originally created for SEGA's CHUNITHM CRYSTAL, ツクヨミステップ crossed into maimai DX as part of the UNiVERSE PLUS update on July 22, 2022. It also appears in ONGEKI R.E.D., making it one of the songs shared across all three SEGA rhythm-game titles. A separate version with VOCALOID GUMI appears on YURRY CANON's first album 人間劇場 (Human Theater), and the jacket art, carried into the maimai release, features the character No.9_ニナ.
