Sooo.. The Hashiras and lowers were at the Hashira headquarters, yapping to each other until they hear some knocks at the door. They all get up and Gyomei opens the door.. Gyomei sees all the orphans he took care of when they were alive and sees SOOOO many relatives..

Zentisu’s grandfather walks up to Zenitsu. Inosuke’s mother runs up to Inosuke. Tanjiro and Nezuko’s family runs up to them. Uzui’s wives and his seven brothers run up to him. Sanemi and Genya’s family run up to them. Rengoku’s father and little brother run up to him. Mitsuri’s family runs up to Mitsuri. Obanai didn’t have anyone so he stuck with Mitsuri. Giyuu’s sister runs up to him. So Muichiro was standing there.. looking around for his twin brother, his mother, and his father but he couldn’t find them.. he thought he was alone until..

Yuichiro (his twin brother) : “Muichiro?…”
