Honestly this doesn’t surprise me. Where they got up to in the anime isn’t worth buying. We got a touch of the story and a couple cool fight scenes? The story still has a bit to go and the people who buy Bluray would probably wait for the whole show? Or you know… Buy ecchi
I only found out about it recently. It is still pretty offensive, but in a hilarious way.
I did watch the dub, which based on some of the subs I’ve seen, the dub is filthier!
