A kid and a skeleton ghost solve problems with the help of a vending machine full of other ghosts. The whole thing runs on dream logic, where a lost denture hunt becomes an actual adventure because the show treats a child's small world with complete seriousness. It's gentle enough for kids but weird enough that adults recognize something real underneath the whimsy.

Everyone calls a certain back alley the Alley of Ghosts, and Gacharico the Ghost really does live there. The only one who knows is little Miku, whose family runs the candy shop nearby. The shop's capsule machines seem to hold ordinary toys, but inside them are many ghosts, each with a personality and ability of its own. When Miku's grandmother loses her dentures, Miku sets out to recover them with help from Gacharico and the other ghosts. The result is a single-episode ONA that blends comedy, fantasy and adventure.
