Anime Recommendations

[Bob Schroeck]

Okay, I'll admit it.  Peg and I are way way way behind on watching new anime.  But we have a history of -- and kind of a standing order for -- giving box sets of anime, usually one series each, to Peg's brother, his wife and their two sons (both college age) for Christmas.  They've enjoyed just about everything we've given them, from Ranma and Tenchi to Stein's*Gate, RWBY , SAO and Black Lagoon.

So -- help out a brother.  What series (available in box sets) are there new that would make good gifts?
