This place is like a freaking maze, ze.

You're not entirely wrong.

Because of the youkai's tendency to attack around the area above this place, it was built to serve as an underground fortress to protect the human villages.

For that purpose, it has a very complex terrain.

Even now, its traps are still operational.

Woaaaa...

That's some bloody good works...

But they were helpless.

At the very least...

They are resting here now.
