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

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

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

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