[Touken Ranbu] There's Something Wrong with That Tsurumaru!

It is said that once upon a time there was a sword named Tsurumaru Kunei. It is said that there is a sword that is capable of causing trouble. It is said that it is a Pipi Crane that even the most calm old knives are gritting their teeth and want to beat. It is said... The master of a certain xxx Honmaru who did not want to reveal his name: I understand the truth, but the key point is that the sword brought back by our Honmaru is a little abnormal? Woolen cloth? A time traveler: What can I do? I'm desperate too! Question: When I wake up, I find that I have traveled to a sword, and there is an unknown system following me. What should I do? Answer: Needless to say, just keep on acting! PS: The character belongs to the boss, and the Honkai Impact belongs to me. If you don't like the writing style of an elementary school student, you can quit. The author's heart cannot bear to be hurt. PPS: The food for the sword was almost eaten, so I had no choice but to open it myself. PPPS: I highly recommend Mikazuki Online Dark Fall. This article inspired me. It may be a little similar, but I definitely did not plagiarize it! One last thing! The author has never played Touken Ranbu. To be precise, my mother deleted it right after I started playing it, so I may not have a good understanding of the characters of Touken Ranbu. I hope you can give me more opinions! Intent: Discussing n worlds that Tsurumaru may go to
