Homura would chuckle a bit in reply to that, judging by the look on her face she clearly didn't expect it to work all that well in the least... Though, if Nanaka were watching them she might notice the shredded up shadows not exactly fading. Instead flowing around formlessly like a goop for a moment.
"Nah, I didn't at all. Woulda been a disappointment if it worked too well, I was more curious how you'd react."
Blocking isn't the move she expected, but magical girls who can use shields and such do exist. Considering Homura's general focus in combat upon raw speed, such a trick might be painful to get around for her.
"Lilith, Mother of Monsters!"
The shadows that had been cut up would congeal into a single form, Lilith clearly focusing upon them for the moment as Homura leaps a bit back with her blade ready. Soon enough, the persona's spell becomes apparent as a shadowy figure of a girl with a long ponytail holding a spear takes shape upon Nanaka's other side.
"... Huh, that one kind of reminds me of... Nevermind actually, just hadn't tried this trick before so I wasn't quite sure how it'd work out. Makes sense she can create things to fight for us though, given some myths."
They'd mostly stay in a defensive position for the moment, though Homura and her new creation clearly getting ready to do something shortly.
