I think I can see where this is going, the MC will give each one a seal, Danzo kidnaps Nawaki, the MC along with Orochimaru and Tsunade go to rescue him, Danzo dies and the end of the root
To be honest i think bang or garou template will be overpowered.
Bang and garou both have white hair.
Their rock smashing fist make them top tier in opm universe.
Another one is gojo satoru.
Finally the story is moving forward, despite the MC being as charismatic as a door, with him being almost a robot the story in general is good only the MC has no personality or emotion.
Does the Root have seals to stop the mc's sensing? It is different from others ninja and i don't see tobirama teaching his student a way to get past it
Tobirama could also guess the lineage of the people he sensed, so at the end of the exam mc would sense a senju in Root and boom
