One Piece Chapter 1024 is titled “A certain someone”.

– The first page of the chapter are a summary of how is the situation is in some parts of Onigashima.

– The fight between Kaidou and Yamato continues.

– We will see Yamato’s flashback, it takes place after Oden’s death 20 years ago. Yamato was 8 years old back then and has a bumpy face.

– Yamato used to be called Onihime-sama (Demon Princess, something like that).

– It also appears that she was capable of using Haki with “Conqueror Haki” and she defeated several of Kaidou’s subordinates in her way.

– It seems like Yamato was imprisoned for going on a rampage in Onigashima.

– Kid Yamato is locked in a cave with 3 powerful samurai, one of them seems to be Shimotsuki Ushimaru.

– While Yamato is in the cave with the 3 samurai, they read Oden’s journal (it seems Yamato can’t read or something like that).

– The 3 samurai open the cave breaking a rock and go out (probably to fight Kaidou).

– At the end of the chapter (in the present) Yamato and Kaidou use their “Raimei Hakke” at the same time and they are tied.
