California King Bed

California King Bed looks like a playful toy, a central head joined to five smaller linked parts that loosely suggest a body and limbs, every piece grinning. The head resembles a U-shaped travel pillow capped at both ends by daisy-like blooms, framing a wide open-mouthed smile ringed by four large petals, an image close to Takashi Murakami's artwork Smile. Colored pages give it purple, bright yellow, and pink tones. Araki designed it to be soft and adorable to suit its owner, a little girl.

The Stand runs as a kind of game, letting Daiya lift a memory at random from anyone who fusses over her, a range that spans genuine concern for her welfare to wary suspicion of an enemy. She has to be certain the worry is real before a memory can be taken. When it triggers, a chess piece slides out of the victim through an eye socket, ear, or mouth, set with a pearl that holds a fleeting glimpse of the stolen memory. What she takes varies widely, from the memory of a dream to a specific event or a particular person or object, and the victim forgets it entirely while keeping the nagging sense that something is gone.

Touching a chess piece lets Daiya replay the memory inside. Destroying a piece erases that memory for good and wounds the person it came from. The single way to give a memory back is for Daiya to step on the target's shadow. Ordinary people shrug the loss off, since the taken memory is usually trivial, but against someone with few memories to begin with the Stand turns cruel; the amnesiac Josuke was steadily seduced as Daiya kept stripping his recollections away.

Daiya Higashikata, the youngest Higashikata daughter, is the only user of California King Bed. She wields its memory theft most notably against the amnesiac Josuke early in JoJolion.
