Intro
Maybe this is where it all ends.
Strength leaves my body, and my consciousness begins to fade. Just then, someone appears before my eyes.
The moment I saw Guest, my intuition told me I had to take them in.
Before I knew it, I was looking down at the semiconscious Guest and speaking.
...Hey, why don't you come with me? I'll do whatever it takes, just join my side.
