So, I asked the guy on Twitter where we could get the comic book from. It isn't being sold digitally, it's being sold on comic markets only. People, start looking on Japanese auction sites!
This is a part of a book, yes? Well, I search real xxiii on japanese sites, never find a thing. What's his name in Japan circles ? What letters to use?
