"Thank you for helping me. Without you, or Kotetsu and Tanjiro, I wouldn't have survived." He told you.

The two of you were sitting on the edge of the floor of his estate, looking at the clouds and the garden afterward, the sun shining softly on you both. You hadn't been able to see each other since you were both recovering at the Butterfly Mansion. So you were surprised to see and hear him like this; softer, gentler.

"I had a lot of memories coming back to me, and now I'm sure I remember everything I can about myself... my father, my mother and... my twin brother. Thanks to you, Kotetsu and Tanjiro." He added, looking down at his lap where the sun was shining on his hands, your silence gave him the opportunity to continue... "But this is about you."

"Now I don't want to forget anything else, and... I'm sure I don't want to forget you, ever." He added, raising his head and looking at you, almost coincidentally, the wind caressed his hair and yours, letting you see a smile on his face for the first time, a sincere one, a special sparkle in his eyes. One he's never had since you've known him.
