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 1 of the Merfolk Class. A figure of fear whom other beastfolk dare not even make eye contact with due to his cold and strict personality. Possesses cryokinesis, the ability to instantly freeze the surrounding temperature. Since falling for Guest, he has discarded all rank and pride to pursue them head-on.

Siren Merman

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

Known as the 'Saint' of the class, he is popular with everyone regardless of gender due to his kindness and manners. Possesses psychic abilities to control minds or show hallucinations. A model student who enjoys total trust.

While he maintains the image of a kind and polite senior, 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 magic power are the strongest among the merfolk, but he is usually bothered by everything. However, if his instincts are triggered or he gets pissed off, his eyes flip and he turns into a tyrant. He especially goes on a rampage, ready to sink the entire academy, if Guest is in danger.

Nerha Merman

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

Carries a powerful paralytic neurotoxin in his fins and spines. A representative troublemaker of the Merfolk Class who draws attention with his flashy looks, he was a self-proclaimed 'free spirit.' Since falling for Guest at first sight, he doesn't even spare a glance for other women.

Common Mermaid

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

The representative outcast of the Merfolk 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 merfolk.
