Yuki had returned from Suna and the fight against the Shukaku just a short while ago and the full restoration of her interface was put in line behind detailed reports for the Entity. Of course, Asakura knew of the fight, but she hadn't been allowed to accompany Yuki. When she had initially returned, Asakura talked relentlessly and, at the close to their conversation, promised to bring a bento over the next day.
For the most part, Yuki declined to her offer, but there was little to no chance that Asakura actually listened. So, the night came and went, and Yuki sat at her kotatsu. Believe it or not, Yuki did sleep, and she was still dressed in her green striped pajamas. She waited for her breakfast.
