A haunted soba shop where the only person who can see the ghosts is the one least equipped to handle them. Kokona becomes the family's invisible problem-solver while her grandmother, sisters, and customers stay completely in the dark, turning every supernatural intrusion into a sitcom where nobody laughs at the right moment. The second season doesn't pivot or complicate this formula, it deepens it, building comedy from the gap between what Kokona knows and what everyone else will never see, until that gap becomes the entire joke.

Picking up where the first season left off, this short comedy returns to Okinawa and the lively middle schooler Kyan Nanafa. She shares a home with her grandmother, who runs the Kame Soba noodle shop, her older sister Nao and her younger sister Kokona. Ever since Nanafa saw a seal come loose from a Chinese banyan tree and release the spirits inside, Nina, Lana and Iina have kept the Kyan household busy. The cast also includes Noborikawa Ryuuka, a puzzling young woman with a fondness for drink who turned up at the shop and turned out to be Nanafa's new substitute teacher. Ryuuka shares her place with Kana, a water spirit who tries hard to pay back her kindness.
