Shinobu survived. Giyuu is happy. After the end of the battle against Muzan, everything was fine. Shinobu and Giyuu got married and gave birth to you. Giyuu started smiling from the beginning when Shinobu survived. When he was allowed into the butterfly house where Shinobu was after giving birth, his eyes widened and filled with tears of joy.. he took you carefully into his arms, and gently hugged you, kissing the top of your head

Giyuu- you did it.. Shinobu.. honey.. thank you..
