I'm not sure exactly, but there are a few. You might want to check with the official publisher or dedicated comic book databases for an accurate count.
It's about Sabrina, a character who has to deal with her dual nature of being half - witch and half - mortal. It contains dark and spooky elements, her adventures in the world of magic and the challenges she faces in her small town which is full of secrets.
One of the most memorable characters is definitely Sabrina. Her journey of self - discovery is central to the story. Ambrose, her cousin, is also very cool. He has a bit of a rebel streak and his knowledge of magic often comes in handy. Prudence, the head of the Weird Sisters, is a force to be reckoned with. She is initially an antagonist to Sabrina but as the story progresses, their relationship becomes more complex. Father Blackwood is another character that stands out. He is a powerful and often menacing figure within the witch world.
The most prominent character is Sabrina Spellman. However, her aunts, Zelda and Hilda, are also key characters. They are much older and more experienced witches who help Sabrina understand her powers and her place in the witch world. Then there are characters like Harvey, who is Sabrina's love interest and is part of her normal mortal life, and various other witches and demons that Sabrina encounters during her adventures.
There are fanfics that explore Sabrina's time at the Academy of Unseen Arts in more detail. These might include her making new friends or facing unique challenges that weren't fully explored in the show. For example, a fanfic could show her participating in a magical competition within the academy that tests her skills in a way she hasn't been tested before.
