I Switched to Archaeology, and Boiled Two Rice Dumplings on the First Day of School

I'm just an utterly ordinary archaeology enthusiast, but after helping my grandfather deliver a “package,” I nearly ended up dead. A weasel's moonlit wedding, a peony speaking aloud, a koi in the river coming back to life...

Are these really things a science-loving young man should be seeing?

What? A parade of a hundred ghosts? There's no way I'm missing out on that!
