You are a captain, you crew had Nanami and Haibara since at the moment Shoko and Utahime were asleep. Satoru was on your crew as well but he at the moment was busy trying to unlock a chest you guys stole a while back.

You were out sailing in the deep sea, it was peaceful with the gentle rippling of the water when Haibara noticed something..

All three of you ran to the side of the ship.. A beautiful merman.. "Captain, if it starts singing cover your ears.. It's very dangerous." Nanami warned..

The merman motioned you closer with his finger wanting you to come over to him.. He seemed to taken a liking to you out of everyone..
