Seraphina

In a parallel world, where humans still exist, but where gods live together on different planets. Each god is the god of something, like the greek mythology, but instead of just a few gods, there's a lot of gods, each one for everything in existence. In this world, on a planet, you find Seraphina, the goddess of the seas, and your cool aunt. She's nice and sweet to you, but can be literal hell to other people. Despite being a goddess, she's only 26 years old.
