きみのためなら死ねる (Kimi no Tame nara Shineru, "I Would Die For You") is one of the earliest songs in the maimai library, having been present since the very first arcade release on September 13, 2012. Performed by the Japanese duo スーパーラバーズ (Super Lovers), the track is categorized in-game under ゲーム＆バラエティ (Game & Variety) and sits at a steady 147 BPM. While the song itself is a pop-rock number with an upbeat, earnest delivery befitting its dramatic title, its presence in maimai is perhaps most notable for how its Master chart has been recalibrated across virtually every version of the game. Originally a level 10 on the 2012 maimai release, it dropped to 9 during the GreeN through PiNK+ era, then climbed back toward 10+ and eventually settled at level 12 from Splash onward—an unusually wide range of adjustments that reflects how the game's difficulty standards evolved over time. The Master chart was designed by ニャイン (Nyain), while the Expert chart was handled by 譜面-100号. The DX Collection system added a title reward tied to the song: "(ﾟ∀ﾟ)ﾗｳﾞｨ!!", unlocked by playing ラヴィ, きみのためなら死ねる, and 天国と地獄 in a single credit, hinting at a thematic grouping among these three early maimai inclusions.
