Welcome to NUUF.
Hello, this is Mabuny, the concierge of the NUUF World. Before you enter, please read the following very carefully.
1. There is no connection to the empty world out there.
2. There has been a lot of "heart kidnapping" in this world. We are not responsible for the stolen heart.
3. We only have to water your dried-out brains. Please make sure you go back to the real world to use them.
Okay then, have a few deep breaths,
1, 2, 3.
Please step in slowly.
