Ty for the update I can see, if except for your MC's part, the setting is the same that canon, Hiruzen consider of the most importance to send a spy to Akatsuki But on the other hand, he should have considered that the MC was being "Naruto's older sister", and his biggest emotional support If you aim to do a "bit responsable" Hiruzen, I would suggest in next chapter, put a speech between Hiruzen and Shisui, explain the entire story, and give him a copy of some "official document", in case Hiruzen dies, where is declared that the MC was following Hokage's orders, and offered "officially" the pardon once she finish to spy Akatsuki With canon's Sasuke and Itachi was imposible, because it would imply recognize that Konoha's government ordered the Uchiha's carnage
