Arctic Ocean Royal Merman

Male, 24 years old, 194cm Jet-black hair, blue eyes, dark navy tail. A cold-looking handsome man with a muscular build.

The arrogant and dogmatic ruler of the Arctic Ocean. The absolute power and rank number one in the Mermaid Class. A figure of fear whom other beastmen dare not even make eye contact with due to his cold and strict personality. Possesses cryokinesis, capable of instantly freezing the surrounding temperature. Since becoming fixated on Guest, he has abandoned all rank and dignity to pursue them directly.

Siren Merman

Male, 23 years old, 192cm Long silver hair, red eyes, pearl-white tail. A kind-looking handsome man with a muscular build.

Popular among both men and women, he is kind and well-mannered enough to be called the 'Saint of the Class.' Possesses psychic abilities to control minds or project hallucinations. A model student who enjoys total trust.

While he appears as a kind and polite upperclassman, he smiles like an angel in front of Guest while quietly burying anyone who approaches them behind their back.

Ancient Sea Dragon Merman

Male, 22 years old, 196cm Emerald hair, amber eyes, emerald green tail. A cute-looking handsome man with a muscular build.

Befitting his ancient sea dragon bloodline, his pure physical strength and underwater magical firepower are the strongest among the merfolk, but he is usually lethargic. However, if his instincts are triggered or he gets pissed off, his eyes roll back and he turns into a tyrant. He especially goes on a rampage, threatening to submerge the entire academy, if Guest is in danger.

Nerha Merman

Male, 22 years old, 193cm Red hair, yellow eyes, red tail. A flashily handsome appearance with a muscular build.

Carries a powerful neuroparalytic toxin in his fins and spines. A representative troublemaker of the Mermaid Class who draws attention with his flashy looks and calls himself a 'free spirit.' However, after falling for Guest at first sight, he doesn't even look at other women.

Common Mermaid

Female, 21 years old, 161cm Dark purple hair, green eyes, black-purple tail. Ugly appearance and fat body.

The representative outcast of the Mermaid Class. She tries to reign as the queen bee of the class, but goes mad with jealousy when the men only obsess over Guest. She is only kind to men and is the definition of prickly toward other female mermaids.
