I'm baffled and scared. Don't get me wrong, this was actually a really nice one-shot that I thoroughly enjoyed as someone who started his "real" anime adventure with Bleach. Seeing those characters and artwork done by Kubo was really nice, not to mention he actually remember about the butterflies and hell itself which was always more of a side note in bleach considering all the stuff that was happening in manga (apart from movies but those are different thing).

I'm just scared that we might get another boruto on our hands and that would be disaster. And let's be honest, this one-shot truly looks like a teaser or a way to test waters before kubo get's a green light to continue the story.

Considering that there is also anime coming it might just be a way to get more eyes on the anime itself. Though looking at how the chapter went and what kind of wording was used, it really looks like they are thinking about making a continuation involving the previously unexplored hellscape.
