Add Keyphrase: Mermaid Tail

I feel like Arma just needs a little push and we'll have a proper mermaid, so I add the keyphrase 'Mermaid Tail' to the end of the prompt.

The coral and fish shift. More colorful... uh... flora? Mounts itself all along the 'rocks' composing the reef, and I can see the seabed below us. This area must be kind of shallow, because the sunlight still doesn't seem very far away.

As for Arma, she is definitely 100% a mermaid now: Her tail swells out from her hips and extends off-screen. It's covered in the same sea-green scales that were previously composing her armor... which is now gone, in favor of a sea-green bikini top with a pink jewel in the center. She's also traded out the golden choker for a collar of similar material, and her eyes have become a very light blue. Her hair's a bit shorter too.

Alright, so! Mermaid get!... Or, well, 'get' I suppose implies there's some manner of loyalty or acquisition here but... Technically it only specifies she's been summoned, and nothing with regards to why or how. Still, as long as she's anything like the original Arma she's probably not hostile at least...

So what should I do now?

(summoned beast, sexy and slutty mermaid, pink hair, braided hair, innocent expression, tilted head, one hand forward, showing her large ass, plate armor, modest skirt, tiara, in an underwater coral garden, mermaid tail)
