It does feel a little fast-paced. Like, at the very least Kohaku just immediately accepts that it had to be someone other than the prince that got her village wiped, based on the word of the person she blames for it? I mean, he's a nice guy and all but still.
That said, it seems like a fun enough manga, I don't mind just enjoying the ride, barring a pile-up of massively questionable plot decisions I suppose.
