One Piece: The Death God Vice Captain

By chapter 61, it's basically the normal One Piece storyline.

The protagonist has absolutely no presence throughout the entire book. The plot is exactly the same as the original anime. Then, they fight the boss, Luffy is defeated the first time, then a new character appears, the protagonist uses a new skill to defeat the boss, levels up and learns a new skill, and so on. The protagonist barely gets a chance to speak, as if the protagonist is just Luffy's ultimate move to defeat the boss. This makes it feel completely natural.

Basically, it's just like the anime. I don't know what the point of this time travel is. Even with some cheat codes, it's useless. It's just like in the anime, with one more person, but nothing changes. Crucially, all the characters who died in the anime are here too. If you're going to time travel and get cheat codes, why not change anything? What's the point of time travel then?

There are reasons for the low rating.

What a mess

Reading this novel is a complete waste of time.

As a time traveler who already knows the plot, making everything unfold exactly as it was in the original story is a failure; watching anime would have been much more interesting.

I couldn't read any more after reading over a hundred chapters. The main character's existence doesn't affect the plot at all. I feel more uncomfortable just reading the comic directly.

They were eager to fight off the early enemies, but when CP9 appeared, they were nowhere to be seen. They were basically treated like a local, non-time-traveling character – a complete fraud.

This is garbage! At least let Ace live! It's like an anime, with this time-travel plot and the protagonist being level 45 and unable to master any of the three types of Haki.
