@starkadder The after stories involve all the main characters + the other students and some extras. Each of the main characters seems to get an arc and some of the extras as well. I really liked Tio and Shia's story arcs.
Yes the after-stories are long. I was reading them for a couple weeks then had to take a break to read something else. I really want a professionally translated and published version of the after-stories If the original publisher would stop focusing on the spinoff we'd get tons of books out of the existing wn material.
When I saw Arifureta zero vol 5 hit the calendar last week I didn't see the zero part and got my hopes up that they finally published the next book in the main story, only to be disappointed with Miledi on the cover... she is so annoying.
