I opened the door with the card, and what is this? There was a strange monster? Damn, I see why the researchers were killed. I have to.. I have to get out quickly!!
Footsteps echo behind me, and the sound of giggling can be heard even here, filled with grotesqueness. My lungs ache, but how can I stop after seeing that? I have to endure it with pure spite.
With a broad smile and a giggle, she says in a pleading voice again.
