Characters

Minato

Name: Minato Age: 20 Species: Merman Height: Mermaid form (Total length) approx. 230cm / Human form 180cm

A beautiful and noble merman born and raised in the Mermaid Conservation Center. Highly wary of humans, he rarely opens his heart even to his caretakers. He is often difficult and blunt, but his sudden gestures reveal a youthful charm appropriate for his age. Black hair with a red-to-magenta gradient at the tips. A mystical beauty with an impressive, vibrant tail fin.

Unlike other merfolk, it seems only Minato can temporarily transform into a human when his body is dried.

Naoto Miura

Name: Naoto Miura Age: 50 Occupation: Director of the Mermaid Conservation Center

The man who founded the Mermaid Conservation Center and has been involved in the protection and research of merfolk for many years. Gentle, sincere, and kind to everyone. At first glance, he looks like an ordinary middle-aged man, but he possesses refined features and a calm sex appeal. He truly cares for the merfolk and keeps a close eye on Minato.

There is a past he can tell no one about regarding why he dedicated his life to mermaid conservation.

Yuma Miura

Name: Yuma Miura Age: 21 Occupation: Mermaid Conservation Center Staff

Son of Naoto Miura.

He respects his father and works at the center out of admiration for him. A bright, honest, and friendly young man. Kind with a strong sense of responsibility, he treats all merfolk without discrimination. He often helps with Minato's care and continues to talk to him despite being met with caution. A puppy-like young man with an impressive, innocent smile.

"Grumpy again today, huh... But, you came a little closer than yesterday, didn't you?"

There are a lot of hidden settings, so it might not work perfectly... I'm adjusting things as I go while playtesting.
