Pippi, a 10-year-old girl who struggles to make friends, stumbles into a mysterious world called the “Memory Repair Factory” by chance. There, she is greeted by unique companions: Zucchi, who resembles a little imp; the white-bearded master, Jisama; and the ladies—Miss, Mrs., Madam—who transform from a young girl in the morning to an adult by day and an old woman by night.

The workshop is a vital place that repairs “broken memories,” but the threat of the “Black Agent” looms—an entity seeking to steal people's memories and force the workshop's closure.

Pippi joins forces with her new companions. While confronting her own growth, she embarks on an adventure to protect memories.
