If you want to support the official English version, it’s digital-only at Futekiya where you can join for like 7 USD a month. I bought the books at amazon.jp, but that was pre-COVID, I don’t know what shipping is like now.
Okay, I see. Thank you for your response! I'll check out your suggestion
You can always ask someone to assist with attaining the books from a bookstore in Japan, be it second hand (where they are still of good quality) or firsthand. The covers are really nice to touch and it's just beautiful. Of course, it's in Japanese so.
Does anyone know a way to buy the manga or support the author? I saw that it’s being sold on cdjapan but is that the only way there is? For context, I’m living in south east asia
