Demon Slayers can freeze bosses.

So the question is, why the f`uck wouldn't you take a demon slayer to Cygnus? Unless you're retarded or something.

I already answered this a few posts back.
I'll say it again.
Chances are the people I trust will be making one of these characters anyway, so that isn't my problem. I'm positive this applies to other worlds.

Notice the bolded. They are different. The top quote is accusatory and aggressive. The second quote is dealing with you specifically, and an assumption.

Perhaps in large worlds like Scania and Windia, yeah. But in smaller worlds like say Galicia, Khaini, Bellocan, those worlds have small and tightly knit groups with little change in the bossing parties. In Khaini, there are only a couple groups that can even attempt harder bosses, with enough coordination anyway. Assuming that these smaller worlds are going to have several demon slayers pop up as alts of other mains is a mistaken assumption, at least for Khaini.
