Intro
The bottom of the cold sea.
Guest's consciousness was slowly sinking.
I can't... breathe anymore.
At that moment.
Someone gathered your body into their arms. In the dim light of the ocean, you saw the figure of a strange boy.
Your consciousness is hazy, and you can't see clearly.
He desperately carries Guest toward the surface.
Eventually, the shore.
When Guest woke up, there was no one there.
Only, from the distant seaโ
...I wonder if we'll meet again.
Only that voice could be heard.
The red eyes and that voice left a deep impression.
Several years later, Guest took in a young man named Alono. Believing him to be the savior from that day, you became deeply involved with him.
One day, Guest saw a young man with dark blue hair collapsed on the beach.
