I know how Karin might go to worst situation. But I am hoping that Yamato will keep her safe until Tsunade comes. Karin without any doubt will surpass Tsunade if she becomes her disciple. Hope author will think of an way, like Hiruzen being merciful and Guy, Kakashi and Yamato requesting together. He qill not be able to decline all three of their request.
E. B and C is essentially useless for now as learning something related to medical ninjutsu in less than a week is impossible, we could always revisit medical ninjutsu later, A is good as it increase our chakra control but I don't expect drastic increase though it will probably be significant but I would argue that knowing the skill-set of his opponents would be more useful and it would also be useful in the 3rd round and shinji can train chakra strings in the month between the preliminary aand the 3rd stage but a chance to have all his opponents gathered in one place will not occur again to spy on most of them, While D have the advantages of a slight chance of gaining a talented medic/sensor as a somehow ally it's disadvantages is possible disappointment from yamato which will lead to a lower relationship stat, lower relationship stat with sayuri because of jealousy and annoyance and overall less team stability, being seen as a ninja who is even more delusional than naruto as trying to recruit enemy ninja will definitely give us bad PR in konoha which lock several routes. thanks for the good chapter messy (authour)
D if not then C. There is so only so much we do about this you got to remember that orochimaru and his underlings are in town and there is no way that he will not find out about this and not try to kidnap her in the week and a month that he is around.And we all know about donzo and what he might do and there is only so much a jounin can do and not only that but I think with the 3rd hokage attitude he might not do anything.But it is worth the risk to try because to have her one of kind godly healing is worth it.
Author: "Kakashi Hatake also discovered that clones can be used to speed up the pace of training. For example, if a user creates one shadow clone and trains with this clone for one hour, and then scatters the clone, the user gets two hours of training in one hour, summing up both his hours and the clone's hours. If you do this with several hundred clones, as Naruto does, the training, which may take weeks or months, can be completed in a few hours" I want the hero to train shadow cloning. I understand that a hero cannot create 100 clones and get the result of 100 days of training in 1 day of training, but you can create 1-2 clones getting 2-3x the result of training.
