Not sure which source you used but there's japanese characters in the episode. In comparison, MAX/HBO doesn't have this, you can compare with NanDesuKa to check what I mean.

Of course it has Japanese characters. Erai-raws usually gets the Japanese raws that aired in Japan. You must be new.

@Apelix What do you mean? Can you pinpoint a specific time in the episode when this difference appeared so I know what you mean?

I'm not new at all and even if I were, that has nothing to do with what I said @Haiyami-chan. @Erai-raws, for example on ep 1 at 21:40. Whenever those isekai soldiers talk (in a different language), it shows japanese subtitles. There are other sources who don't have them, that's what I was trying to say.
