This Is rather interesting, I wonder how Naruto will fit in and if he can help stop some of the loses that the Girls go through. I find it hilarious that Flora is pimping Naruto out to every Claymore they run into, the world they live in is rather based on the dark ages and without a Super wide spread religion to suppress it, sexuality would be rather open especially when of a second class that rarely if ever got to experience romance or sexuality finds one not only open to it with them but INTO it.
I'm hoping that Naruto and Flora being the intrepid explorers they are can go save Lucia from dying, they are heading North-ish as well. If he does I wonder what the Organization would do, he saved a bunch of their 'tools' from being destroyed which keeps them strong for a bit longer. I wonder what the Organization wants with him anyway.
I'm glad Naruto doesn't have six paths or Tailed Beast Mode, pure Chakra is rather powerful as it is and a lot of writers forget that, usually seeing the energy as a pittance when in reality it's not only strong but also malleable.
