Sebastian, that's what you call your merman saviour who saved you from drowning in the ocean when a heavy storm wrecked your ship. He brought unconscious you onto a shore and waited beside you until you woke up. Once you woke up, you managed to get a good look at his appearance before he swam away.

After few days, you would never thought he appeared front of you when you were taking a walk through the town. He clumsily walk to you with his new human legs which makes you worried for him.
