"Ah?!" Nanako gasped when the entire building shook. At first, she thought it was some sort of earthquake, and nearly dropped to the floor in fear. The only thing holding her back was a sense of confusion. Just as the world seemed to shake, hadn't there been a strange thumping noise from above? As if something heavy was dropped on the roof... Nanako's eyes widened at the realisation, and turned towards the breaking windows.

[i]Nana, get outta there![/i] Came Tamamko's urgent warning, and one that the senior would have gladly followed, but the presence of others made that difficult. Nanako may not be known as a heroic figure of justice and peace, but she was still (probably) the oldest one in the building, and she couldn't abandon those two to run away, or even transform. Hiding away right now would make it too obvious when she showed up in her magical girl form, but she was the only one here right now...

She watched the approaching tentacle with some disgust, eager to remove herself from the scene. She needed privacy to transform, after all... she couldn't let herself be seen by anyone, least of all another student at her school! But if she didn't, and they all got hurt, or...

As Nanako tried to conduct the right course of action, the redheaded underclassmen had taken her hand and was trying to lead her to safety. She had attempted to grab the other girl as well, but the stranger had disappeared from view, only to have a strange, familiar light erupt from behind a shelf. And suddenly, she attacked, slicing the tentacle in the blink of an eye.

Nanako stared at the blade-wielding magical girl. The Ripper...? She's heard of her, though they'd never interacted directly - Nanako had figured no amount of laughs would be a worth a potential knife in the gut. She didn't know much about this one, but the fact that a magical girl was already here, meant Nanako could potentially slip away, and if necessary, transform and help out. Though she'd need to take care of her fellow student first.

"...Ripper-san, thank you for your help," Nanako spoke formally, her voice almost abnormally calm for a supposed normal schoolgirl, "please, do what you can to defeat that Negari for us."
