Eh, still against it. Going after every little thing is a good way to get Hisana killed and harvested for her eyes and her bodies secrets. I'm not saying we shouldn't use her meta knowledge, just saying that we should be smart about this.
We ARE being smart about it.
We are investigating someone who tried to kill a jinchuuriki and another Academy instructor in canon.
Those are both relevant to our interests, especially since Iruka was one of Naruto's only two adult authority figures.
If you are terrified of investigating a chuunin instructor inside Konoha, within easy reach of backup, and with a certain degree of foreknowledge?
How do you expect to take missions? This is not a safe job.
Mizuki isn't really part of the above
Yeah, I don't agree.
If he's as inconsequential as you claim, then fouling his play is a quick and easy source of brownie points.
If he's an actual threat, dealing with him becomes even more pressing before he fucks everyone over.
We're talking about someone who had the knowledge and ambition to go after the Forbidden Scroll in canon.
With the ruthlessness to set up a child and kill their coworker.
Whether he's working for Orochimaru or some other faction in this AU, or is an independent contractor, we cannot afford to leave him behind us if he's hostile.
Or do you think canon Mizuki would not cut a deal during the Invasion if/when it comes up?
Or assuming he can't get at Naruto, isn't going to try this with another of our classmates?
Off guard ambushes probably were the death of many ninja.
The Uchiha specifically ended up in shit because during the Kyuubi attack, most of them didn't turn up.
That was the original sin that allowed them to be marginalized, and gave Danzo his opening.
The village can handle it is never a good excuse when you yourself are free.
