It gets you in under four minutes, which is the whole flex. Eve trading lines with Hatsune Miku is the kind of pairing that could have been a cash-in for Project SEKAI's first anniversary, and instead it plays like the two of them actually needed each other on the track. Kukka's animation doesn't decorate the song, it keeps pace with it, cutting on the beat until the visuals feel like part of the arrangement rather than something laid over top. There's no dialogue, no exposition, nothing to explain, just craft moving at tempo. The real tell is that Eve dropped two versions the same day, the Eve and Miku duet on YouTube and a Miku-only cut on Niconico, and fans still argue about which one is definitive. If you've picked a side, you already know why this one stuck.

Gunjo Sanka is a one-episode music video that Kukka animated for Eve's song of the same name, which features Hatsune Miku. The song was written to mark the first anniversary of the rhythm game Project SEKAI COLORFUL STAGE! feat. Hatsune Miku. It comes in two versions released on the same day: Eve with Miku on Eve's YouTube channel, and a Miku-only take on his Niconico account. The genre labels are fantasy and slice of life.
