[Touken Ranbu] The Witch

During an operation to hunt down the Retrograde Army, the swords sent into battle encountered a beautiful girl surrounded by an air of mystery. A traveler, a dancer, a helpful stranger, a girl who took on many identities to guide the sword warriors... But her true identity was- Someone who wanted to see the world plunged into chaos for fun, a witch who treated life as a game. Want to catch me? the girl said with a laugh on a street filled with cries of sorrow. Then come and try. √ Written to unwind. It's not long, updates whenever inspiration strikes, but at least once every two weeks. Not paywalled. √ The heroine has twisted values and is a yandere. She's the sort who might plan to destroy the world just for fun, more or less chaotic evil. The heroine's values are not the author's. √ The male lead is Mikazuki Munechika. The ending might be open-ended? The story may include a chapter or two featuring Chaldea.
