――This is a "Mansion of the Stopped Time".

While you are here, The outside world――
The time in the world where everyone was originally, will Never go on.

So, You don't have to worry anything about outside.
When everyone returns, the world will start moving again.

More importantly...
Now that you came to a place like this,
I want you to take your time and relax.

You won't be able to get out of here for a while after all.

Let me tell you, This Mansion is very Mysterious!
When you thought the corridor would continue forever, a door suddenly appear,
When you take your eyes off the door for a little while, the door disappears before you know it...

Even inside the rooms, there's something strange.
There are a Lot of unusual rooms too!
Sun that is dazzling, the Winds blowing, it's just like a room outside!
...I'm sure there are many rooms I haven't entered yet.

Of course, there is an Exit!
But the current you, Won't be able to find it.
...You can't get out of here right away.

The time is stopped outside,
You don't have to rush.

That's why―― Let's all play together!
