JoJolion - Chapter 2
The mysterious man found by the girl is deep in thought. He has no idea who he is or what his name may be. He has no recollection of his past, and at the moment is confused as to where he is exactly. In his hospital room, the man wonders why the nurses are dressed in white and ponders on a little girl calling out her sister and mother, wondering why they look alike. Looking out a nearby window, he can see various birds and butterflies flying about and is able to determine their exact length and species just by looking. He recognizes the tree the birds are perched on to be a Japanese Alder, and also calculates its height. Finally, he sees and recognizes the girl who found him, walking down the hospital hallway, to be Yasuho Hirose. He calculates her height as well, to be 166 cm.
Yasuho enters the room but is startled by the man, who is found sleeping under his mattress. Yasuho asks why he is under there, but the man misinterprets the question, saying that the people in the white garbs told him to stay in the room. She clarifies her question and asks why he would be sleeping in between his mattress and the bed frame, confusing the man who claims one sleeps by applying pressure to themselves via the mattress. After pulling himself out of the bed, the man and Yasuho spend time eating filled mochis parfumed with sesame and honey, which the man likes immediately.
Yasuho finally asks him to tell her the earliest memory he can find; the man replies that Yasuho is his earliest memory, hugging her. He does not know anyone else in the world. Feeling his erection and remembering his four testicles, she pushes him away. Then she notices the man's sailor hat and asks him where he got it from, and then notices the label inside is from a store that she is familiar with. Yasuho then begins to think of a plan for her to take a picture of the hat and ask the shopkeeper about it herself since the man is unable to leave his hospital room. However, the man uses his shoulder to launch a bubble with a star shape on it toward a security guard standing near his room. It pops and causes all the water in her to drain out; she becomes thirsty and leaves to get a drink. The two use this chance to exit the hospital. From the window of his hospital room, Joshu sees them escaping. He claims that Yasuho likes him more than the strange man, since Joshu got sixteen dumplings while the man only got eight. He passes out as a bite mark can be seen on his body.
At the store, they ask the clerk if he knew who bought the man's hat. The clerk is confused, claiming that he was the one who came and bought it. The clerk brings out a book containing past sales, and says that his name appears to be "Yoshikage Kira". He also produces an address of where he supposedly lives.
"Kira" and Yasuho arrive at what appears to be Kira's apartment. Inside, they find the place completely spic and span. Next to the doorway, they find the same sailor outfits Kira is wearing, so they assume that this is indeed his house. Then the man hears splashing noises coming from the bathroom. Someone appears to be hiding in it.
- Several familiar hats worn by characters featured in previous parts are seen around the hat shop such as Johnny Joestar's, Gyro Zeppeli's, and Jotaro Kujo's.
