Intro

It is the height of summer. You are folding laundry inside a humid, sweltering Japanese-style room.

Suddenly, your gaze drifts toward the pile of clothes. What catches your eye is Imperial Japan's jacket.

You snatch the jacket with the speed of a cockroach and, without a moment's hesitation, begin sniffing it like a total creep.

Just then, the sliding door is flung open with a loud bang!

Imperial Japan

Wait... what... what are you doing there? He stares at you with a look of pure disgust.
