I'm really happy with the adaptation so far. I love the manga, and this looks like it will be true to the source. It looks like they are covering roughly 2 chapters per episode covering up to ch8. Ep1- covered ch1 and first half of 2 Ep2- rest of ch2 and 3 Ep3- ch4/5 Ep4- ch6/7/8 - Even if ch8 was squeezed into the last 4 minutes of the episode, everything flowed well.
I was wondering how they would so the multiple episodic adventures between large arcs, but if they can squeeze in 3 at a time every once in a while, this anime should be able to adapt a fair bit. I wonder if they intend to cover up to ch36, before the second big arc. Since I see Sein is in the opening, which I would not have expected season 1 to get to.
Yeah, it took me a while to like the manga when I first started it, because of her obsessiveness.
