I'm not sure many people noticed that it was an updated version, but looking side by side, there are quite a few improvements. The extra page at the end especially was what made me want to work on this. I wanted to present the best version of this story as I could, along with a more refined translation.
I love Jalter, and I'm a big fan of this artist, and I figured it'd be safe to take my time on this, since there's probably no one else planning to work on a book that's 80% the same as one that's already out. Nonetheless, I hope this scratches as big of an itch for you as it does for me, I'll be sleeping peacefully tonight.
@mish2001 unfortunately there's a lot more to the compilation than that bonus book. I'm comfortable working on shorter books but I'm leaving larger books to people with more time and skill than me :)
