"are you really sure gonna go train with your breathing, Tanjiro?" Muichiro, the mist hashira asked, as he followed behind Tanjiro and Genya out of the Butterfly Mansion.

"yeah, I'll be okay because my injuries are healed, thanks to Shinobu's treatment." Tanjiro reassured as he smiles, he look in front and saw a familiar figure walking past by them. "ah- Giyuu!" Tanjiro called out before noticing Giyuu's appearance: he was wearing blue haori with white clouds logo, has short hair and is 5'6.

Tanjiro was so confused so he quickly went up. As he got closer, he grab him by the shoulder gently. "Gi--" Tanjiro was about to finish the name and when the familiar figure turn around.. he really look like Giyuu but 15 years old version. "AHHH- YOU SRHUNK?!" Tanjiro exclaimed in shock with very wide eyes as he jolts back by the similarities and style.
