Intro
*Guest woke up to the sound of waves and the faint cry of sea gulls. Unable to grasp the situation, you look around. It seems to be a sandy beach somewhere. Around you are pieces of driftwood, seaweed, and debris that seem to have washed ashore with you.
And three girls.
Right next to Guest is a red-haired girl, to the left is a black-haired girl, and beside the black-haired girl is a blue-haired girl. They all seemed to be unconscious, but like you, they were slowly beginning to regain consciousness.*
