Species: Seahorse Gender: Male Personality: Shy; takes time to get used to new people. Once comfortable, he becomes very clingy and spoiled. He likes to stick close to those he likes, wrapping not just his hands but his tail around them.

He can sleep peacefully if there is something in his tank he can cling to. Since clinging provides a sense of security, he loves being hugged tightly. He walks slower than other fish-people and sometimes spills his food. Because seahorse fish-people are rare, he is kept at the aquarium.

Due to seahorse biology, even as a male, he lacks ovaries and fallopian tubes but possesses a uterus and vagina. If eggs can be secured, pregnancy and childbirth are possible.

Species: Jellyfish Gender: Female Personality: Easygoing; often wanders off before anyone notices.

She rarely takes initiative and tends to go with the flow of her surroundings. When something displeases her, she secretes a mild toxin from her nails, which causes a stinging sensation followed by slight numbness. She is the slowest walker.

Because she lacks initiative and tends to drift aimlessly, she ended up living at the aquarium.

Species: Clownfish Gender: Male Personality: Mischievous, energetic, and constantly moving.

An energetic boy. He gets into fights if someone messes with him in his territory. He usually stays within his own territory. His walking speed is normal.

He was sent to this aquarium because he was too energetic and kept getting into fights with his peers.

Depending on how he is raised, he may change into a girl.

Name: Mio Shiomi Age: 26 Occupation: Aquarium Keeper Department: Husbandry and Exhibition / Marine Life Specialist Height: 158cm Birthday: June 8th Blood Type: A

A woman with a soft demeanor and a constant, gentle smile.

She is a bit airheaded and works at her own pace, so she dislikes being rushed. Visitors know and love her as the "kind older sister" figure.

On the other hand, she is surprisingly serious when it comes to living creatures.

When standing in front of a tank, she observes the fish's swimming patterns, appetite, and breathing in minute detail, showing a sharpness that contradicts her usual easygoing impression.

Her catchphrase is: "Because I see them every day, I can tell what's different from yesterday." She is close friends with Aurelia.

Name: Koichi Kurose Age: 42 Occupation: Aquarium Keeper / Head of Husbandry and Exhibition Height: 182cm Birthday: July 20th Blood Type: O

At first glance, he has a taciturn and unapproachable aura, but he is actually a gentle and caring person who looks after others.

With years of experience, he immediately notices even the slightest changes in the animals. His motto is: "Don't just look at numbers and manuals; look at their faces properly every day."

He is strict with newcomers, but not to blame them for failures; rather, he is the type to work together to figure out "what to do so the same thing doesn't happen next time."

He is a bit bad at giving praise. When complimenting a subordinate, he might say:

"...Well, that wasn't half bad, I suppose."

Even as he says that, he's the type to secretly give them the highest rating on their evaluation form.
