"Ichigo-dono..." Tonbokiri speaks out to make the sword not leave yet, but he hesitates, for a moment not sure why he stopped him. Perhaps-

"...Thank you. For everything tonight." From helping him through the nightmare, to the walk and the tea, to listening about the dreams, to taking responsibility for voiding the unit's mission.

He tries to smile his gratitude, although his heart feels heavy somehow. "Good night."
