Nope they are the physical manga volumes in English! I bought them on rightstuf anime which were the cheapest I could get compared to other websites. The scanlation here stops right before volume 3 ends and then there are 3 more so I totally recommend you buying the copies whether digital (buy them with SuBlime) or physical.
Please, help me! I have no money to buy all the volumes (broke af), so could you tell me if it's woth buying volume 3 just to read what is not translated? I mean, if is just a extra that makes no difference to the story it's alright, but if it's a real chapter, I'll buy (and probably be hungry for the next two months lol). Thanks in advance! â•®( ̄▽ ̄)â•

I couldn't wait any longer for more updates so my broke ass bought all the volumes
