A kid inherits her grandfather's shop and a ribbon that means everything, then discovers the things she treasures can talk back. The show lives in the space between daily routines and small magic, where fixing a broken toy or keeping a plant alive matters because someone you love trusted you with it. This is comfort television that actually earns the feeling, because the stakes are real even when they're small.
Years ago, Haruka Hoshinogawa made a wish at her town's old cherry blossom tree with her grandfather, who gave her a ribbon decorated with cherry blossoms. Now starting fifth grade, she still treasures it. When the tree begins to wither, her grandfather sets off to see the world and leaves Haruka in charge of his shop. The next day, while she sleeps, her ribbon sprouts an egg, and out comes a Cocotama, a god born from an object that has been loved and cared for. The little god, named Ribbon, ducks back into her egg, which turns into a strange key once Haruka picks it up. Ribbon identifies it as the Key of Wonders and reveals that it has chosen Haruka as the Legendary Contractor of the Cocotamas. Together they keep the shop running, befriend other Cocotamas, and work to uncover the key's secrets and powers in a lighthearted slice-of-life comedy adventure.
