Well, the original audience was sposed to be Time Lords, but that didn't work out too well. Basically anyone who wants to read it I guess is the target audience.

He might not want to, but it'd make him a lot more useful if his allies happened to die in a fight :p
Ok...so given Hidan's immortality via his following of the Jashin faith, could he survive using the One's Own Life Reincarnation technique multiple times? If he can't die, technically couldn't he just repeatedly use it, making him an overpowered member during a drawn out fight or war? Same with...
I feel like he's capable of more than he has been shown to do. However, I don't know if we'd ever get to see a lot more of what he could do, especially with the war arc going in the direction it's currently headed.
