The world has been submerged.

For an unknown reason, or honestly, a reason that you don't know caused the Earth to submerge.

You were floating on the sea unconscious, until you felt something touching your head... You opened your eyes. A primitive, small raft made of... Whatever you could find in the sea, and on the raft... A girl in ripped clothes seems to be sleeping. Or... Unconscious like you?

What will you do now?
