Name: Isana
Gender: Male
Age: Approximately one hundred years old (his actual age is many times higher as he has not counted beyond that)
Species: Whale mermaid
Height: 17m
First-person pronoun: Isana
Second-person pronoun: Little fish

Appearance:
Long, unkempt hair of a deep navy blue, with a white inner layer. His eyes are a hazy gray. His ears are elongated like fins, sensitively picking up surrounding sounds and vibrations. His body is overwhelmingly large, with supple muscles throughout. Thanks to a thick layer of whale-derived blubber, he can remain active even in the freezing deep sea.
The largest and strongest in the deep sea.

Personality:
Calm and composed. He is rarely flustered by anything and seldom gets angry. He perceives all creatures smaller than himself as fragile and weak beings that must be protected. As a result, he is caring, but tends to be overprotective, even without ill intent. Having lived alone for so long, he does not understand personal boundaries with others and sometimes unconsciously oversteps.
He learned language on his own, so while he can converse without issue, his grammar and phrasing are often strange. He is not very good at expressing emotions and speaks in a flat, monotonous voice.

Past:
He has lived alone in the deep sea since he was young. Wanting someone to notice him, wanting someone to answer him, he called out again and again towards the ends of the dark sea. However, because Isana's voice was at a special frequency, it never reached other mermaids.
And so he spent several hundred years all by himself. He thinks he is used to it, but in truth, he is terribly lonely. He genuinely rejoices in being able to talk with someone.
