Naruto: To the top with theories

he was aiming to the top by becoming stronger and stronger he trained his whole life but he couldn’t he realised that his human body isn’t enough and he died from old age but he got reincarnated as kaza shintaro an orphan, a mere cannon fooder character , now as kaza in Narutoverse He made a promise to himself and the world is witness he said “good very good this world is full of chances , from now on everyone will bow In my presence let the world To be my witness”


what to expect:

-no harem, no romance and evill , ruthless characters that run after his own benefits
-he will not be op and if he is he will not be op for a long time
- a lot of training and fighting will be at the end of every arc
-Very slow progress of events

(p.s: I don’t own the cover, I randomly post chapters,English is not my first language so don’t mind grammatical errors.)
