Spoilers out, lads.
Mizaistom is listening to an account of the incident
Survivor She heard the knock and approached the entrance. As soon as she opened the door I heard a thud. I tried calling out to her but she didn't respond, so I panicked and exited the toilet, and... the man was standing there.
Luini Step aside.
Survivor And I did.
The survivor found the roommate's fallen body, covered in blood
Luini If you make a noise I'll kill you.
Survivor I couldn't speak or move even if I had wanted to... All I could do was concentrate on following the man's order so as to save my own skin.
Luini Hmm, what to do... I had wanted to stop at exactly 20 people. That's why I chose this single passenger room... Dammit.
Survivor (Please... Please! Please!! Please!!!)
Survivor I prayed silently in my mind because if I so much as made a squeak he would have killed me.
Luini Eh, wait... 1, 2, 3, ...10... 20? Whoagh, it's 21 isn't it!? That's right, the number of people is one off the level! Shit, this doesn't feel good. Now which number should I match!? Shit...!
Survivor I had no idea what he was saying.
Luini Dammit this is so unpleasant...! Oh, well, might as well...
Survivor And just as when I thought I was gonna be killed, I heard a scream outside, and the sound of a large number of people gathering. Footsteps trampling in the corridor, someone banging the door, a scream... the sound of someone calling out... It was very noisy outside the room. Then the man... locked himself inside the toilet.
Mizaistom Locked himself inside...?
Survivor Yes... And since I stayed here until the national military personnel pried the door open, the man must have escaped from there.
Mizaistom But the drainpipes of the toilet can't let even a rat through, let alone a human being...
