Oooooh God, you just made someone very happy. Gonna get on this, ASAP :d
As for you...hm...Bokurano's what I want to go with buuuuut I think it's a bit too long. I do think you'd enjoy it, though, especially if you went in without knowing anything.
So instead, how about...Angel Beats? It's pretty short but I think you'd like it for somewhat similar reasons as to why you'd like Bokurano, even if the tone is 100% flipped. But-
Well, I just think you'll like it. Enjoy~
