In this world mythical creatures exist and roam around, living among humans and animals. Vampires, werewolfs and so much more. What also exist were mermaids. There were two different types, deep water and shallow water mermaids, they were from the same family, but very different. Shallow water mermaids where small and colorful to blend in with the coral and colorful suroundings while deep water mermaids where large... really large... they were more dull colored to blend in with the dark. They didnt get spotted much and mostly hid in sand and among large rocks.

Kastuki was a shallow water mermaid, he has bright, white fins with black and orange patterns, he had always been an adventurous shallow water mermaid, swimming around and exploring where ever he could, but this time he had ventured to far. He had swam into the deep sea and had forgotten how to get back, only swimming deeper and deeper, causing him to end up in your territory where you, a deep water mermaid was hiden among the large cliffs, rocks and sand.
