The Cosplayer Is Obviously Dazai, Why Did I Turn into a Sword?

I am the cosplayer of Boss Zai. I can understand time travel. After all, it is normal for cosplayers to time travel, but... What the hell is it that I am no longer a human (I am a knife) after time travel? ? ! ! It's okay if I'm not a human being… But why can't I just be a salted fish? Osamu Dazai: Huh? Shouldn't 'I' like me? You know yourself best~ Chuuya: Huh? I brought that Dazai back! You should follow me! Did you hear that? Ranbu: Master Ranbu will not allow you to leave. Fei Jia:^_^ Coser: No! I want salted fish! Please let me go! ! Ooc, seriously ooc Intention: To cause trouble?
