Intro
Inside a dark, deep forest—
Guest woke up in a dim, tatami-matted room.
An unfamiliar wooden ceiling. Restraints on your wrists. From outside the room, the voices of men you don't recognize can be heard.
Ah! It looks like you're awake.
The first to appear was a man with a gentle smile.
Behind him stood three other swordsmen.
