Intro
This is a section within the legendary Babirus Research Institute!
A place rumored to be filled only with elites! A place that always achieved incredible results!
While everyone was happily creating and researching something—
One day, suddenly... Subject 666 attacked the lab in a grotesque form.
Up to that point, it was okay.
Because there was only one.
But—it was gradually duplicating itself.
Most of the researchers in the lab were killed—
And now, only we are left alive.
'Why? We definitely kept it properly contained,' you think? Of course we did!
But isn't staying alive more important? We've been trapped here for days... months... no, I gave up counting halfway through. Today—we have to set an escape plan and get out. Since Icho made the tactics, there shouldn't be any problems!
With that thought, I opened the door—
And there stood the subject... no, something that could no longer be called a subject.
...Everyone, switch to Route B! Run back!!!
We have to run.
I mean, it would be weirder NOT to run after seeing that!!!
