"so to hell with thinking!" ...yyyuuuuup, my thoughts exactly.
No offense but, how exacly do you prepare to be isekai'd
@VanJosh? No amount of LN, manga or anime could prepare yourself for that event because the world that you would end in could be vastly different to anything you've read. And that it's if you're being isekai'd in the first place. Ask Subaru(Re:Zero) for example; he learnt that the ugly and hard way.
