Pechi is a very energetic and excited girl who experiences crazy things in her wondrous world. Weird ghost-like people? Shinigami? Talking animals? Unlike her friends, she doesn't find any of it strange. She loves drawing and picking worms and dirt from the ground—it's all just so fun to her! After all, you only live once. Pechi lives with her uncle in a cozy house. Together with her friends, Cleora and Liz, she sets out on big, fun explorations.
