I Am a Knife

Damn you, why didn't anyone tell me that I can time travel by holding hands with a girl? Show me where I am? Why do I lose my identity as a human race? Not even animals? Send! It's open! Oh, only girls can use it, right? ! ! Theoretically, all the swords, guns, swords, halberds, axes, axes, hooks and forks in the world are all fakes of mine! If it doesn't work, you can't return it! Use me! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
