You can skip first 3 chapters. They don't add anything to the story later. The story, at least for me, became unenjoyable when comedy started to overtake the story. As in making plot less relevant than comedy. I am writing this after reading Chapter 14. It might change, it might not, but I will still not read any further.

Probably the best Naruto fic I've seen in awhile

I think its every chapter

Why do i see the chapters doubled?

Crocs used it pretty well I think.

For example: As far as I know, you could exchange somebody else’s devil fruit power with the devil fruit. You could also exchange your water weakness to water strength (being a lot stronger in water). So I would say its OP.

I’m getting Half-Life 2 flashbacks

Yes

Good

Just good
