Kaisa was a family name that appeared in Chinese web novels and was often described as a wealthy, powerful, and influential family. The image of this family is usually cold, ruthless, cruel and evil, but they also have another side, such as they have strong economic strength and political power, or they are people who will protect their family at all costs. Kaisa's novel images often appeared in various fantasy, urban, historical, and fantasy topics.
Without more context, it's really difficult to tell the full story of 'kaisa hai naseeban'. It might be a story related to someone's fate or journey, but that's just speculation. Maybe it's a title of a local tale, a family story or something else entirely.
Well, Kai'Sa's back story is quite tragic. She hails from Icathia which was overrun by the Void. She was basically alone in that hellish place. Over time, she adapted to the Void's energy and used it to create her armor. It's not just a protection but also a weapon. The armor has some Void - based powers which she uses to fight in the League. She's like a survivor who has turned her struggle into strength.
The characters included the male protagonist, Igor, an unknown age, powerful magic, and ancient wizard bloodline.

I'm not sure specifically as there could be many novels with 'the librarian' in the title. It might be about a librarian's daily life, adventures in a library, or perhaps a mystery involving a librarian.
