Demon Slayer? Blade of Providence

[The story unfolds based on the shortcomings and loopholes of Demon Slayer: Kimetsu no Yaiba, including conspiracy theories] [Also known as - "I traveled to Demon Slayer: Kimetsu no Yaiba and just wanted to live, but I was reborn over and over again and finally ended everything myself"] "You mean, your family was eaten by ghosts?" "Chirp!" "Is that why you joined the Demon Slayer Corps?" "Chirp!" "Why do I think you are eaten more by humans? Why don't you set up a human-killing team?" "Chirp!... Chirp?... Chirp!" The above is the conversation between Wu Ming and a sparrow. He has been killed by ghosts and humans, so he should join... The human-ghost killing team? In short, this is a very weird world full of bugs.
