What a surprise..! He was probably just going to let his hair stay down until he found it in himself to get up again and head off to his own room. He hadn't expected Tonbokiri to offer to help with it, let alone even have any ties to help keep his hair secure.

He never really let anyone else touch his hair besides himself and Horikawa and if anyone else had offered, he probably would have given them a skeptical look, but Tonbokiri had a good head on his shoulders, and Izuminokami could honestly say that of a lot of the swords he was able to meet here, He trusted Tonbokiri a lot.

He clears his throat a little and quickly turns his head in hopes that this kind spear didn't notice how flustered he might have looked.

"It's a lot of hair to work with, it's true. Are you sure you're up for the task?"
