Tilct
To be honest, this whole drama is unnecessary, he has a seal that prevents anyone from feeling him, and chakra chains that prevent the use of chakra...all he has to do is wait in a precise location and he could easily kill Danzo.
every uzumaki jonin had these.... uzushio is still gone... if danzo was so easy to overpower hed never have amounted to much, he got caught unaware once..... hes 10 years younger than shippuden atm and is in his prime as a shinobi.... kaito is very strong for his age but hes not strong overall, just has op abilities but weak foundation due to lack of experiance and strength. and if we assume hes able to use them perfectly then just end the book and say he killed everyone revived minato and they lived happily ever after.
