Huh... I didn't expect that.
I'm actually excited. I think the last time that happened was the first season of Non Non Biyori.
I love this manga, and as a general rule, the manga I love don't get adaptations, and when they do, they're mediocre at best. And it's not just that they're mediocre at best, but that I can predict accurately that that's what they're going to be, because there's no way an anime studio is going to capture the magic of the manga (Akebi-chan no Sailor Fuku is a perfect example).
But this... they might just pull it off. In fact, if it's done right, it could be one of those exceedingly rare cases - like Lucky Star or K-On - in which the adaptation is actually better than the original.
If nothing else, it's pretty much guaranteed that it'll be worth it just to see and hear the full rollercoaster effect of a Wada monologue.
