Oh, man. What a place to end it! There are so many unknowns that seem like they'll be relevant. Like, where did the Parano group end up is obviously the biggest question, but also...
What did the Margrave want from Renji? Was it related to Forgan's invasion of Alterna?
Is the No-Life King really back? What happened to him in the first place?
Has there been a new generation or two of Volunteer Soldiers while everyone was away? Will any of them become relevant someday?
Will Ranta revert back to being an awful person after reuniting with Yume?
These post-timeskip stories in particular have been really exciting. I'm excited to see what comes next!
