命ばっかり (Inochi bakkari; officially translated as "It's Just Life") is a VOCALOID song by producer nulut (ぬゆり), performed by the virtual singers flower and 結月ゆかり (Yukari Yuzuki) with guitar by Takeaki Wada (Kurage-P). The track first appeared on nulut's 2017 album plotoplan and was added to SEGA's maimai on April 26, 2019, as part of the maimai FiNALE update under the niconico & VOCALOID genre. The official music video was produced by the illustrator アボガド6 (avogado6), whose surreal, emotionally charged visual style complements the song's introspective tone. The arrangement is built around a steady 128 BPM beat, blending melancholic synth textures with a crisp electronic-pop foundation. The lyrics explore themes of emotional exhaustion, self-doubt, and the difficulty of genuine human connection. A recurring motif, dreaming of butterflies, echoes the classical Zhuangzi parable about the blurring of self and reality. The song also appears in SEGA's CHUNITHM AMAZON PLUS, where it received separate chart designs by écologie and Moon Strix. In maimai, the song's MASTER chart (level 12.7, designed by はっぴー) is notable for its 68 Slide notes among 631 total notes, creating a dense, flowing layout. The EXPERT chart (level 10.0, designed by 某S氏, "a certain Mr. S") features an unusual balance of 38 Hold and 38 Slide notes within a 364-note total. The difficulty ratings were adjusted multiple times across maimai DX versions before settling at their current values from BUDDiES+ onward.
