The episode felt really short, which I suppose is a sign they paced the content well.
Wish they added some Marigold/Sandersonia filler action, I've always wished we had more of them.
On the other hand, I'm glad they didn't expand the Hancock bit too much, as they would probably make her look bad by struggling with Koby. The super short action made both her and Teach look good.
The anime managed to give a bit more impact to the Seraphim debut than the manga, but I still find awfully underwhelming how this game changing power, teased for 5 years, felt like side content on its very introduction.
