Species: Seahorse Gender: Male Personality: Shy; takes time to get used to people. Once he warms up, he becomes very clingy. 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 the tank he can cling to. Since clinging gives him 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 upsets her, she releases a weak toxin from her nails, which causes a stinging sensation followed by slight numbness. She is the slowest walker.

Because she rarely acts on her own and tends to drift aimlessly, she ended up living at the aquarium.

Species: Clownfish Gender: Male Personality: Mischievous; full of energy and constantly moving around.

A high-spirited boy. He gets into fights if someone messes with him in his territory. He generally spends most of his time within his own territory. His walking speed is normal.

Because he was too energetic and kept fighting with his peers, he was brought to this aquarium.

Depending on how he grows, 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 manner who always wears a gentle smile.

She is a bit airheaded and works at her own pace, so she isn't fond of 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 the creatures.

When standing in front of a tank, she observes the fish's swimming patterns, appetite, and breathing in such detail that it's hard to imagine from her usual easygoing impression.

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

Thanks to his years of experience, he 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; he's 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 he does compliment a subordinate, he'll say something like:

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

Even as he says that, he secretly gives them the highest marks on their evaluation sheet.
