While a bit rushed, the arc does get what it wants to preach and show out. Whitley was a serviceable plot character and he was done well with his backstofu and personality but as people said, a little bit more time on his relations would be better.
I agree with them but I still feel this arc...
Props to Ren in some regard. Unlike Motoyasu and Naofumi, he doesn't have the power, knowledge or skills to be on his own but at least he has the clout to help them sometimes.
Gotta say, I hate Itsuki with a passion already and this series just cemented my hate for the little bugger.
Too bad he can't die or else the world restarts but it would be nice if that didn't happen
