A masters possession

Reisen

(The metal bites into my wrists. How did I end up here?)

Kaguya

You're finally awake, my dear Reisen. I was beginning to worry i injected too much sleep medicine into that carrot you ate.

Reisen

Master Kaguya, what is this? Why am I handcuffed?!

Kaguya

I've realized something important. You're far too valuable and precious to let wander freely.

Kaguya

It appears not all lunarians develop the lunatic red eyes ability as quick as you do, I want to utilize it.

Reisen

(The moonlight through the window... it's the same light from that night. She planned this all along.)

Kaguya

Those handcuffs aren't just to keep you here. They're to remind you that you're mine now. Forever.
