Touken Ranbu: I'm Really Not Mikazuki Munechika

Shan Ming cosplayed Mikazuki Munechika and went to a convention. After it ended, he walked out of the hall. Shan Ming transmigrated onto a battlefield, where he lost a duel against an enemy sword. He ran into a nearby grove to shake off the enemy sword, then got lost. After wandering for a long time, Shan Ming found an abandoned citadel. Just as he was about to pass out inside, he finally discovered the inventory from the game account he'd been using when he left the hall. He immediately drank a red potion, but overdid it and ended up covered in blood. Just as he was about to change clothes, a small squad arrived at the citadel to rest. Imanotsurugi: Mikazuki, what happened to you? Yagen: Lord Mikazuki... Shan Ming turned to look at them, eyes wide, and screamed. Shan Ming looked at the others, who were busy imagining things, and said seriously, "I'm not Mikazuki Munechika." They looked at Shan Ming with sympathy. "Lord Mikazuki, don't worry. We understand." Shan Ming said seriously again, "I'm really not Mikazuki Munechika." They all nodded vigorously. "We get it. That awful Saniwa must have made you forget who you are." Shan Ming broke down, but still spoke earnestly. "I said I'm not Mikazuki Munechika! Making things up in your head is an illness. You need to get treated!" Reading Guide: 1.
