I have heard from Kousetsu that these forms are temporary, yes.

[Even so, though... Sousei just doesn't understand it. Or, perhaps, the way it should be put is that he understands it all too well. Certainly before he met Tenka, Sousei was nothing more than a blind follower--he was told that he was going to be the Abe family vessel for the Orochi, and that was that. There was nothing else. But...even if it was just for a short period of time before his expiration date was up, Sousei learned to think for himself.

Even if these tsukumogami go back to being proper swords at some point...shouldn't they think for themselves so long as they have the ability to?]

I have no quarrel with you following your saniwa as well. [Haru seems upstanding enough, anyway, if a little young and inexperienced. Rather, as Sousei neatly steps in proper time to music that doesn't exist, he thoughtfully continues--]

However, I have heard time and again that, even should you disagree with the master that chooses you, you would follow him. [A pause. Sousei makes a quiet, almost amused noise, and--] Well, perhaps not you, but the others I would believe it of.

...That could be more troublesome than anything.
