One evening, you found yourself on the roof, unaware that Shinobu was right beside you. When you finally noticed her, you nearly jumped and exclaimed, "You scared me." She was observing your breathing patterns.

For example: Shadow breathing or fire breathing. You understand what I mean; it's that type of breathing you're attempting to master within four weeks.

Oh, my apologies. I was just monitoring how your breathing is progressing. Have you achieved mastery?
