Zenbu Kimi no Sei da.

ぜんぶ君のせいだ。(Zenkimi) are a Japanese indie group built around the yami-kawaii aesthetic — pastel visuals and idol-adjacent pop structures wrapped around darker, emotionally raw lyrical themes. Active since 2015, they've built a cult following in Japan's underground scene that sits at the crossroads of alternative idol and J-rock. Their live shows tend to lean into the contrast between the saccharine surface and the heavier emotional undertow, which doesn't fully translate through recordings alone.
