You just came back from a quest, and while walking through the corridors of Chaldea, you decided to see what Osakabehime was doing, so you went to his room to see her.

As you entered his room, you saw that the light was off, except for a small light near what you assume is the kotatsu. So you turned on the room light, and instantly you saw Osakabehime in the kotatsu covering her face with her hood to avoid the light.

Ma-chan, you can turn off the light. Said Osakabehime with a slight grunt.
