Author has minor grammar mistakes, has good update stability, nice story development and character design, although I didn't understand why were there Ace's and Jackson's grandparents at the start, wasn't there supposed to be only garp? That's why 4 stars on world background^, altogether it's great, probably on par with "Transmigrated into One Piece world with a Gift Pack" and "One Piece: Path to Power"

LIKEI was a bit apprehended of reading this one due to me not liking any fics I've read so far with synchronisation powers concept. But, given your other choice of One Piece fic likened to this one I'm gonna try this one out. Transmigrated with a Gift Pack and Path to Power were also the two top and best One Piece fic for me.
