JoJolion - Chapter 6
Summary
As Ojiro Sasame falls from the upper floor, the Protagonist grabs him, throws him inside the apartment. He then holds the former by the jacket, taking the antidote for the venomous snakes as well. Sasame is stunned as he doesn't recognize the protagonist, and claims that he isn't Yoshikage Kira. However, the protagonist isn't satisfied with his claims and continues to violently slam Sasame against the furniture.
Then Ojiro tries to fib out of the situation by lying. He asks the naked girl if the protagonist was the one who kidnapped her during her vacation, which she agrees to. However, the protagonist continues to kick him until Sasame clarifies the situation. He confirms his mistake by comparing the protagonist's hand with a model Kira made of his own hands.
Sasame then shows the protagonist and Yasuho a photo of the real Kira, saying that the protagonist doesn't look like him, while still acknowledging a certain familiarity. He also explains that he isn't Kira either, but has a grudge against him as he mocked of his passion as a surfer and somehow made him eat his fingers. He went on to explain that he rented an apartment room above Kira's and set up all sorts of traps in Kira's room, using the girl stripped naked as bait. He also revealed that the photo album was set up by himself, so that he could frame Kira. He waited three days in his temporary room for Kira to return, so that Ojiro could kill him.
Yasuho recognizes in the photo the spring where she found the protagonist. After knocking out Sasame for good, the two go back to the spring.
In the spring, the protagonist plunders all the water and finds the corpse of a man, later confirmed to be Kira, who died three days prior and more strangely didn't have testicles. Afterward, the protagonist is taken to live with the Higashikata Family, under the name Josuke Higashikata.
Meanwhile Ojiro's hostage, who fled the apartment during Ojiro's interrogation, is seen hiding in a trash can, still naked and lost. Covering herself with the can and lamenting about going back to Tokyo, she stands up, catching the attention of a couple of boys riding by. The naked girl trips and rolls over, exposing herself in front of the dumbfounded boys.
