(How indeed!!! The surprise should really be all his and he smiles delightfully at Kogarasumaru. He'll surrender Konnosuke willingly, letting the crow sword take his place instead. For all of the trouble he likes to make, he's actually a good sword, especially when it comes to his elders and he naturally, places his hands on his shoulders, giving them a rub,)

Now, this is a surprise.

I'm well. (As well as one can be after suddenly becoming human,) Who would have thought we would meet like this!

How long have you been here, Kogarasumaru?
