I'm not entirely sure as I haven't read it in detail. But generally, it might be about witches and some sort of conflict or adventure related to them. Maybe it involves a story where the witches are being persecuted and there are characters who either want to burn them or save them.
I don't know specifically as I haven't read the novel. But it could have witches as main characters, perhaps a powerful witch who is the target of the 'burn the witch' sentiment. There might also be a hero or anti - hero character who is involved in the situation regarding the witches.
The story of the Scarlet Witch manga can be seen in the following examples:
In Marvel Comics, the witch Emily Wenderlich was a woman with superpowers. She used to be an ordinary witch, but in an accident, she gained the ability to control magic.
As time passed, Emily West began to use her powers to fight against evil forces, including the Dark Magician Sorren and the Dark Wizard Bane. She worked with other superheroes such as Iron Man Tony Stark, Captain America Steve Roger, and Spiderman Peter Parker to fight various threats.
During a battle with Soran, Emily West discovered that she was not the only witch. There were others with similar superpowers. She decided to explore these superpowers and learn how to use them for justice.
In addition, Emily West also established a complicated relationship with other characters in the comic, such as Gale Gardner, the ally of Iron Man Tony Stark and Wonder Woman. These relationships and storylines continued to develop throughout the manga.
