One Piece: I Am King Arthur

The appearance of a loser with the soul of a knight king, who is no longer a knight king, still claims to be a knight and a king? Are you kidding me? A knight is not a harem, and a king is not a narrow-minded, selfish coward who is just a silly coward in front of the person he likes (harem is not love, it is just the kind of liking that can be discarded when you get tired of it, based on your own understanding of those characters).

Seeing the Marineford War scene, I couldn't accept the protagonist's despicable behavior. While he himself claimed he joined the Marines to fight Whitebeard's side for prestige (the fact that joining Whitebeard's side and fighting the Marines would obviously have yielded more prestige was clearly ignored), that's not the problem.

Why do I feel that the attributes of Heroic Spirits should be higher than those of the pirate world?

I've seen a lot of One Piece fanfiction where the characters are mostly around 1.8 meters tall. Since you're writing One Piece, can't you at least fix this glaring flaw? The characters in the regular One Piece series are all very tall. If you're only 1.8 meters tall and you were to fight Garp and the others, you'd look like a little kid!

You're telling me a Heroic Spirit doesn't understand magic?

All four attributes are A, and his swordsmanship is so much higher than when he fought Kizaru in Sabaody Archipelago, yet he still couldn't beat Doflamingo? I just want to ask, aren't these attributes enough to be considered an Admiral? Was he just trying to show off before he even reached Admiral level? So stupid.

Let me tell you about a major downside. Those who can handle it, and those who can't, should probably quit sooner rather than later. It's like changing bodies in one world after another. I'd rather study here; even I, an eight-year bookworm, couldn't handle it.

This is ridiculous. They're supposed to be saving people from the Type-Moon era, but Sakura's been stuck here for ages! Is she just brain-dead and deliberately trying to piss people off?

"Hahaha, as a swordsman, you actually put your sword away? Do you know how powerful Lord Buggy is?" Buggy burst into laughter as he saw the invisible sword in Arthur's hand disappear.

The Type-Moon universe is truly awful. Sakura is no longer complete; her tragic fate remains unchanged. According to your timeline, if she goes to the Matou family to kill Zouken Matou, Sakura will no longer be Sakura. If you're not a Fate fan, don't write Fate stories.
