Demon Slayer: The “Mu” in Muichiro Means Infinite

Wearing a two-hundred-yuan cosplay outfit, he pushed open the door of a convention-center restroom and stepped straight into the world of Demon Slayer. The moment he arrived, a demon attacked him. The person who rescued him was Muichiro Tokito, the very person he had cosplayed using temporary hair-dye spray. Same face, same hair color, same clothes. The Demon Slayer Corps members took one look and reached a conclusion: they were twins. He immediately denied it three times over: “That's not me. I didn't do it. Don't make things up.” But no one believed him. Not even Muichiro. The amnesiac young Hashira stared at his face for a long time. He couldn't remember a thing, yet he gripped his wrist tightly and said, “You're important to me,” then refused to let go. He couldn't beat Muichiro, and he couldn't get away, so he was forcibly dragged back to the Demon Slayer Corps. No one knew who Yuichiro Tokito was. Everyone thought he was Muichiro's long-lost twin brother, including Muichiro himself. Although Muichiro kept saying, “I don't know who he is,” whenever anyone tried to take him away, Muichiro would silently draw his sword. He was forced to stay, bearing the name of someone who had died and watching over a boy who was still alive.
