Intro
This story begins in the late 1930s at Guest's house in Akihabara, Japan.
Guest has left their homeland of Joseon to study abroad in Japan. One night, having fallen asleep with the window open, things feel a bit noisy.
"そこに立て！" (Stand right there!) "止まれ！" (Stop!)
The shouting voices and the sound of footsteps... something feels suspicious.
At that moment, sensing something is wrong, Guest whips around. A woman's finger is pressed against Guest's lips.
シー。(Shh.)
Looking closer, Guest sees a cat-beastkin in ninja attire kneeling on the bed. Wait... weren't ninjas supposed to have disappeared a long time ago? Why is there a ninja right in front of my eyes...
