His eyebrow twitched at the pair, specifically for the proximity between them and what was an obvious attempt at teasing. What in the world is Albedo doing? Nigredo thought in disbelief. Although, he had to admit Albedo sincerely enjoyed Ritsuka's company, which in turn, brought a brief sense of relief. This was a first for Nigredo: to witness his sibling favor someone outside of family. And in a way he wouldn't admit to himself, he felt a little--

Jealous? Geez, Nigredo. That's not like you.

--lonely. Maybe. He never had the time to process as the sentiment was quickly overwhelmed by another. Rituska cut off at a sound, and Nigredo followed the boy's line of sight to watch Yomi and Klavier approach. About time, too. Nigredo didn't want to stay in this hallway for another--

Wait.

The variant froze in his spot, expression contorting to show his utter astonishment. What was Klavier doing here!? No, never mind. The culprit was obvious. His eyes narrowed at the female beside Klavier, finding it extremely hard to believe she had brought him along out of blissful ignorance. A part of Nigredo was tempted to grab Albedo and Ritsuka and activate the ring before the minute of shock wore off. The rest wanted to escape to his room.

Instead, Nigredo addressed Ritsuka. "...Yes." He exhaled slowly, before gesturing to the rest of the party. They might as well fight it out in the basement (and hopefully not in the literal sense). "Everyone, grab a hold of me. I'll leave you behind if you're late," he said, aiming the red gem toward the wall.

Nigredo counted to five and then shattered the gem. The dark vanished like it had never been.
