Don't worry, Kousetsu-san, I'll keep you safe. [ Nanoha had seen a tsukumogami transform before her eyes before, so she wasn't too surprised when Kousetsu changed into his true form. Instead, she just grabbed the tachi with a nod and turned to face the fire. ]

We shouldn't charge back into the lobby, that's too far away. All of you, get into the back room and I'll put out the fire! [ Poking around the desk meant that the entrance could now be considered the far side of the room, and with all the bookshelves threatening to burn down, there was no way making that trek could be safe for the rest of the group.

Besides, if they let the fire keep burning, there was no telling how many other people could be affected. No, it was best to end this fire here and now. Even if what she was going to do would be considered just a bit rough. Just a bit. ]

Hayate-chan would have just frozen everything, but unfortunately she's not here, so...

[ If and when she sees the other three are safe, Nanoha will start charging a beam. Fire needed three parts to burn: Heat, oxygen, and fuel. And since the fuel for this particular blaze was wood and paper, it would be a relatively simple task for her to annihilate those with a few well-placed Busters.

Probably. Failing that, she could still fly everyone out. ]
