Crunch. Crunch.
Powerless to stop a further sequence of rather morbid murders, the ringleader of the show had been the one to take the next fall. Tanaka Gundam had taken quite the heroic fall, having fought his way through the culprit's attack and afterwards, their tra- pshshshhh, as if. To the great Beelzebub, oh unholy Lord of Flies, this offering we present. To devour, feed from and henceforth bring evil unto the world.

The sacrifice was torn to shreds by his very own animals.

Interestingly, a puzzlebox with a heart-shaped lock lays on the torture table from before. To add on to this, every animal that has consumed a limb or the offering's head head has a number on its housing. You aren't sure of the order, or of what the numbers represent. When put together, they read 3 5 12 5 19, in any order.

Now stuck in a place with a definite serial killer, you are presented with three reasonable choices. Do nothing, blame someone, or try to run. Run anywhere. With the stench of death hot on your trail, you feel your gut clenching as the realization of a possibility that you might meet your end tonight settles in.

Keep one thing in mind, dear victim.
❤ Time is precious. ❤
