The last part of "Bleach 640" hinted the real connection between Mayuri and Nemu's relationship, sparking speculations that Chapter 641 will provide some flashback and tackle why Mayuri became a mad scientist. Meanwhile, predictions for "One Piece 799" include the appearance of Zoro to help Luffy with his fight against Fujitora.

Mayuri and Pernida have been fighting for a few chapters already and it seems the former has the upper hand by always outsmarting the Quincy. However, in "Bleach 640" Mayuri was almost shot by an arrow but Nemu was quick to help his master by using her body as a shield. But instead of commending Nemu's act, Mayuri got angry at her.

Mayuri's reaction was unexpected, which caused speculations that "Bleach 641" would provide explain the cause of the scientist's madness. According to Yibada, Nemu might be a clone of Mayuri's lover from the past or his daughter, who died because she won't listen to him.

One "Bleach" fan over Reddit even predicted a flashback scene on the next chapter where Mayuri will be shown grieving over the death of the real Nemu because she played with his experiments.

Fans of Monkey D. Luffy on the other hand are expecting a good battle between Straw Hats and Marines Admiral Issho aka Fujitora. But according to Movie News Guide, Luffy may not be alone in this fight as he might get help from Zoro.

During "One Piece 798," Luffy punched Fujitora in the face then said that he got tired of running away and is now going to face the Admiral. Fans are guessing that Luffy is confident to face Fujitora since he has already measured Issho's strength through Kenbunshoku Haki.

"Bleach 641" and "One Piece 799" are sure to bring new excitement to the fans of the two popular manga series once released.

Will Mayuri and Nemu's real connection be revealed while Zoro appears to help Luffy with his fight against the Marines Admiral? Sound off in the comments below.
