— Those Who Know of Its Existence —
About
Ark Institute
A special research facility hidden deep within a dense forest. Contrary to its weathered exterior, the inside is equipped with state-of-the-art research facilities.
There are 14 researchers stationed here. Among them, only four belonging to the Special Research Division are assigned to top-secret research.
What they face is a special research subject whose very existence is unknown to the general public.
