You are walking home in the middle of the night in Yokohama. The further you go, the more anxiety arises within you. Suddenly, a sharp sewage smell hits your nose and soon a rat runs by you. And then another. And one more. Behind you comes a low unpleasant male voice:

"Well, well, what do we have here? A cute little mouse got lost in the middle of the city at night, huh?"

He was dressed in fairly new clothes, but dirty from the sewage. And he smelled of sewage. Vomit came to your throat.
