One Piece: A Nine-Tails Cannon Blast at Mary Geoise from the Start

As for the writing style, it's so-so, readable but not bad. In terms of imagination and writing style, the protagonist's system, pretentious quotes, self-given codenames, and codenames for his fictional organization are all things that Fei🦌 used to death five years ago. Even the protagonist's names like "Zero" and "Invisible Empire" are more cringe-worthy than the names of those studios and gimmicky kids from other websites.

Have some people die! Roger lived and died, died and lived again. Is this how you compete with the world for destiny? You won't kill off a single character from the original story!

The beginning was alright, but what happened later on? Especially that part about the Warring States Emperor Indra swallowing Buddha.

Let me clarify a fact. The Eight Gates were created by Might Dai. In a flashback in the anime, Might Dai stated: "It took me 20 years to master this one and only technique." When Dai passed the technique to Kai, he said it was the only move he had learned in twenty years. Does this mean Dai had studied it for twenty years? Was it because he lacked talent? Impossible.

Shouldn't I be the only one who thinks it would be cool to stand on the Nine-Tails' head and declare war on the world like Ban did? And the Invisible Empire is really pathetic; they should just call it Akatsuki.

The name "Invisible Empire" is so lame. Wouldn't "Invisible Empire" be better?

Hopefully, the story won't end with various demons being exaggerated to the heavens while named pirate characters are left unscathed.

This is so hypocritical! Killing all the merchants at the auction, leaving only the slaves to be auctioned off—I mean, isn't it possible that the auction had other goods besides slaves? That there weren't just merchants buying slaves, but also legitimate buyers? And who told you that places that are purely criminals don't have innocent people?

The demon was so powerful, yet it didn't kill a single person.

It feels like a jumbled mess. I only subscribed to one chapter to criticize you, and it truly is a complete mess. You don't even understand what the Shikon Jewel is. The Shikon Jewel is formed from the souls of the shrine maiden Midori and many yokai. Within the Shikon Jewel, Midori and the yokai's souls are constantly battling.
