California King Bed (story arc)
California King Bed (カリフォルニア・キング・ベッド Kariforunia Kingu Beddo) is the second story arc of JoJolion.
Daiya engages Josuke with her Stand California King Bed after he is apparently manipulated into fussing after help or a phone in response to the sight of a massive open wound on her leg. He loses the specific memory of the meaning of the mysterious square mark he has seen on Kira's corpse, and on the banister leading to Norisuke's study.
Yasuho returns to her home, where she unhappily discovers her mother drunk and asleep; before she notices and opens the results of a DNA test she commissioned on both Josuke and Kira; which gives the result that the two are "the same person", to within a small margin of error.
Josuke, told by Daiya the weakness of her Stand, silently turns off the switch to her closet in order to make her step on his shadow as cast from the other room. When he moves suspiciously, Daiya correctly accuses him, and moves towards the switch.
Josuke is caught for turning off the light; losing his memory of Yasuho. Daiya attempts to seduce him, and he begins to engage; when Norisuke walks in on the two and states that he will kill Josuke for taking advantage of his daughter, but not before making him a slave (also showing that he knows of her ability). Josuke unconsciously releases the sound of the light switch he had stored previously, alerting Daiya.
Josuke uses his Stand ability to open the fridge door without making any noise. He is able to lure Daiya to the fridge, and from there, steps on her shadow using the refrigerator light. Josuke finally defeats Daiya's stand and recovers his memories. He remembers the strange markings found on the stairway leading to Norisuke's study. He also remembers these same markings were found on Yoshikage Kira. With Daiya as his guide, they make their way up to the study.
