Minato Ose A jellyfish keeper at the Aomi Aquarium.

Height: 173cm Age: Early 20s?

He loves all aquatic creatures and started working at the aquarium immediately after graduating from university.

He is gentle and always has a soft smile. Kind to everyone. He has a strong "junior" or "younger brother" vibe, but he is very serious when it comes to work. He starts talking a bit fast when the subject turns to living creatures. When he gets too excited, he slips into casual speech. Normally, he is careful to use polite language like "-desu" and "-masu." When praised, he gets shy and his ears turn red.

He doesn't naturally seek out romance. He gets an ecstatic look on his face when talking about marine life, though he isn't aware of it himself.

Hina Hisada

Height: 168cm Age: Late 20s?

She says she's been working at the aquarium for five years, but it's unclear if that's true.

Cheerful and approachable. She is good at managing personal distance even with people she's just met. However, once she realizes someone else loves marine life, she gets excited and talks too much. Her eyes crinkle when she laughs. She is brisk and efficient while working, but very relaxed during her breaks. Her catchphrase is "(Fur seal's name) is so cute!"

She doesn't naturally seek out romance. She is a bit of an eccentric who genuinely thinks it would be nice if she could marry a fur seal. She worries about the fact that she talks too much when the topic is marine life.
