Seerin is fanon character and one of HTFF villans.


Seerin is a blue siren with some fish-like features and melodic voices. She's very dangerous and sensual creature yet look pretty and innocent. She can be aggressive when someone provokes her, good people or bad people, she'll kill them no matter what.

In her spare time, Seerin usually sings a melodic song while sits on rock, shore and surface of water. By doing this, someone who near her will approach and Seerin will kill him/her in brutal ways.

If she's not killing the characters, there'll be a chance the characters become her allies/slaves/lovers. When her partners get killed, Seerin will either eats them or leaves their corpses behind.

Seerin in most of the times is shown to be friendly and nice character but harmful or innocent but sexual. According to the creator, Seerin represents lust, one of Seven Deadly Sins, it also make sense since she lure her victims to be her lovers, she lust for love and blood, and look pretty innocent but actually sensual.

Her deaths involves fire-related things, evaporated and sea animals.
