Well, a one-shot but oh boy! My hype for Bleach has risen to new heights! Art is still good! Also, I think it's safe to assume that this won't follow the Naruto -> Boruto route.
Seeing some of the old characters with their new looks (especially Rukia and Lisa) just made this new chapter a really refreshing start. Of course, I can't forget the appearances of the new Shinigami, like the 8th division vice captain (yes, that gyaru).
Also, judging from the title of this one-shot alone, it's pretty obvious that the Bleach manga's plot will explore on another realm called Hell. It's a good thing that Bleach made a comeback so that the current lore we have concerning Hell will be expanded.
Last but not the least, this one-shot presented us a shocking revelation. To think that some of the dead characters will make a comeback, and possibly all of them being villains.
And yes, this ended in a cliffhanger, but all the more reason for the hype of a new story arc!
