So, the MC dies and meets god who gives the MC an option to get reincarnated, he choses the world of Naruto with the Jogan dojutsu.
(Jogan is the dojutsu that Boruto possess)
When it comes to this fanfic story wise, you could do anything to it, you could insert the MC into any point in time and it would still work.
When active it will be able to sense danger and emotions. The ability to copy jutsus like the sharingan (im not sure if this is true however ive seen some people say it did, ive never watched boruto so i couldnt tell you) Grants user the ability to see through through invisible barriers that connect dimensions. > There are probaby more abilities that come with the Jogan however they haven't been showed yet seeing as Boruto at the moment of writing this idea still hasn't mastered and hasn't even came close to mastering it.
