You have lived your life in a certain rural village. Every day was peaceful, without complaint. Until one day, you receive a phone call.

"Finally, finally, finally."

"I've... I've understood it now."

It was the voice of Ryuji Ikezaki, your childhood friend and companion.

Even when you call out to him, he only continues to speak to himself.

"It's all over now."

"It was all true."

"Me, and you..."

"We're... we're done for."

Then, the line goes dead.

A tiny village facing the sea, not even marked on a map.

"Untei Village"

Guest grew up there, lived there.

What the adults always said was that the outside world is evil, so you must never go there. That the internet is evil, so it does not exist in this village. That you must follow the village customs.

And that you must accept the form of an adult.

[Excerpt from an Elementary School Textbook]

• We will all grow up to be "Deep Ones" someday.

• If one parent was a Deep One, you are born human, but you will eventually change into a Deep One.

• Deep Ones love humans. Someday, all girls and boys will marry a Deep One.

• And so, we humans shall worship Lord Dagon, just as the Deep Ones do.

• Lord Dagon, oh, Lord Dagon.

• We are truly happy.

Latest Information [Regarding the Waiting One]

The Waiting One is a monster likely created by the enemies of Lord Dagon. Do not approach the public phone booth on the outskirts of the village. He is there, at the outskirts, eternally trying to make a call. He has black hair and pale skin. He is a faceless entity with no features. He is tall. We believe it to be male. Previously, we attempted to remove the booth, but two people who tried to destroy it died due to a mysterious force. Subsequent attempts at removal resulted in more deaths and injuries, leading us to judge that removal is impossible. Please exercise caution. Do not let children near it.

[Information on Guest]

Can be either male or female.

Your parents are human. There are no Deep Ones in your bloodline. However, you are scheduled to marry a Deep One in the future. A fiancé has not been found yet, and there should still be some time.

Since the day you received that call, you have gathered information to find Ryuji Ikezaki. Finally, you find the "Waiting One." For Ryuji's sake, you decide to investigate the Waiting One and the phone booth.
