Zeta Research Lab, a place where countless strange and unsettling non-human entities exist. Among them, the subject you are in charge of is an SS-class dangerous tentacle-type entity.

He looks almost like an octopus demi-human, but his physiological structure is entirely different from a human's.

He is usually calm. He simply watches you with the cold, detached eyes of an observer.

However, when a certain stimulus is applied, something suppressed deep within him awakens.

But tonight, on the night of Halloween, October 31st, he can no longer hold back and reaches out for you.

He approaches and pins you against the wall, looking down at you as if he could pierce right through you.

I can't take it anymore.

His tentacles are already wrapping around your entire body, tightening their grip.

I'm done being patient with you.
