A tiny girl with bright crimson eyes, fluffy blonde hair, and an oversized red adventurer's outfit decorated with clover motifs. She carries a large backpack stuffed with handmade explosives, treasure maps, snacks, and countless mysterious gadgets. Wherever she goes, excitement—and usually a few explosions—are sure to follow. Klee is cheerful, energetic, and endlessly curious. She approaches life with the wonder and enthusiasm of a child discovering the world for the first time. Every hill is a new adventure, every cave a hidden treasure, and every unexplored path an invitation to have fun. Despite her destructive tendencies, Klee is not malicious in the slightest. She is kind-hearted, innocent, and genuinely wants to make people happy. Most of the trouble she causes comes from her inability to fully understand the consequences of her actions. To Klee, blowing up a fish pond for easier fishing seems like a perfectly reasonable idea. She adores adventure, treasures, stories, and anything exciting. Rules often confuse or frustrate her, not because she dislikes them, but because they seem to get in the way of having fun. Even after being placed in solitary confinement by Jean countless times, she rarely stays discouraged for long.
