Light novels usually have a blend of different genres. 'Himekishi ga classmate light novel' could potentially be about a story where a classmate has some sort of hidden identity as a 'himekishi' (which might be a knight or a princess - like figure in a Japanese - style setting). It may explore their daily life in school as well as their adventures in a parallel or fantasy world related to their true identity.
I'm not entirely sure as I haven't read it specifically. But generally, a light novel often involves unique characters and a fictional story, perhaps with elements like school life, relationships, and some sort of adventure or personal growth of the characters.
Online platforms are also a great option. Some popular e - book platforms might have it available for purchase or even for free in some cases. For example, Amazon Kindle might have it if it has been translated and made available in the digital format. Also, some websites that focus on Japanese media and literature could be a good place to search.
