Nanako
Nanako winced a little at the sight of the gaping hole still in the man's chest, still bleeding as he walked out just like that, with his by now usual mutter of 'foolish'. Before Nanako could wonder about where he was going next, however, the white-haired man spoke up from right beside her. She watched the elf leave for a moment longer as the man spoke before turning her attention to him. Her reply swiftly died on her lips, however, as she saw the man had finally opened his eyes and she found herself wishing he hadn't.
It wasn't that they were pitch-black, but instead just entirely empty. Like a yawning maw of nothing opening wide to swallow her whole. The squirrel girl lurched back on instinct, fluffy tail going still behind her as her eyes widened in surprise. She managed to keep her balance in her seat on its very edge, but she felt trapped by those eyes, trapped between wanting to look away and being unable to. Those black pits seemed to widen slightly, Nanako feeling for a moment like they might suddenly surge forth and engulf her entirely. The worst of it, though, was that it almost felt familiar, even though she was sure she it shouldn't be. Like she'd seen this before, not some endless void to fall through eternally, but simply nothing.
Cracks of that nothing flitted across her own eyes for that briefest instant, so small and with such speed that even the squirrel girl herself might not have seen it, even if she'd known it had happened. All she felt was that rapture that had held her melting away. She finally looked away, quietly letting out a breath she hadn't realized she'd been holding.
"Ah, okay then," she said, managing to keep her voice steady, "Have you met him before, or was that what you figured out from that whole fight just now?"
