One possible plot could be that Karin Maaka, who already has some vampire - like qualities, discovers a hidden power within herself that fully turns her into a true vampire. She might struggle with the new urges and powers at first. For example, the thirst for blood could be a major conflict for her, especially if she has moral objections to harming others to satisfy it. Maybe she meets other true vampires who either help or hinder her journey of self - discovery in her new form.
If Karin Maaka turns into a true vampire, her relationships with her human friends would likely change drastically. They might be afraid of her new vampire nature, especially if they see her display vampire traits like super strength or a thirst for blood. Her family might also be in shock and try to find a way to 'cure' her. However, she might form new relationships with other vampires who understand what she's going through and can guide her in the vampire world.
One common theme is the struggle between Karin's vampire side and her human - like qualities. She often has to make choices that balance these two aspects of herself.

Karin could use her modern - day knowledge to help them survive, while Ren could use his wits to blend in.
