I've heard a lot of good things about Saint Young Men, a gag manga involving Jesus and the Buddha on vacation. I'd heard absolutely nothing about the author's other ongoing series, but somehow that gets the anime adaption.
Wasn't sold early on; the main character's shtick is a bit annoying, and the crazy girl's shtick is one I always enjoy, but not terribly original.
Then the kappa showed up.
The kappa is pretty much all awesome, every second he's in the show.
