Three jellyfish with annual passes spend their days drifting through an aquarium that feels less like a tourist trap and more like home. The comedy isn't trying to kill you; it's the kind that makes you smile when you're not expecting it, the way watching something genuinely unbothered changes the temperature of a room. This is what comfort actually looks like: no stakes, no arc, just three creatures who know their place and show up anyway.

Three jellyfish with annual passes to the Enoshima Aquarium have turned their favorite destination into a second home. Mizukurage, a moon jellyfish, and Akakurage, a northern sea nettle, share their frequent visits with a Pacific sea nettle companion. Set in Enoshima in the Shonan region, this ten-episode comedy ONA was made to promote the new Enoshima Aquarium. This is lighthearted comedy that doesn't take itself seriously for a second.
