≠彡"/了→ (read as キミツアー / Kimi Tour) is an original instrumental track by composer Kenji Mizuno (水野健治), added to maimai でらっくす Splash on October 1, 2020. It holds the distinction of being the first maimai-exclusive original song commissioned as an online qualifying round entry for the KING of Performai (KoP) tournament series, debuting as a score attack event reward alongside other challenge tracks. Mizuno, who had previously arranged the ongaki song 夏色花火, wrote this as his first purely instrumental composition for the maimai series. The song's title is written in leet (1337) cipher, the characters ≠彡"/了→ are stylized substitutions that visually encode the katakana reading キミツアー. This playful typographic gimmick carries through to the chart credits, where the Master difficulty's designer names are rendered in the same style. Musically, the track delivers an uptempo hardcore sound driven by 222 BPM kick patterns and dense percussion, earning a reputation among players as a solid warm-up for other high-BPM stamina charts in the Splash era. The Master chart stands out for reaching exactly 1,111 total notes, a palindromic "zoro-me" (ゾロ目, repeating-digit) count that arrived within the first month of Splash's operation, following felys -final remix- as one of the earliest songs in the version to cross that threshold. Its note placement was also choreographed to sync Break notes with the "kira~n" sparkle effects in the accompanying music video, produced by the artist group Gunjou Licorice (群青リコリス).
