Since I don't have detailed information about this 'Sono Light Novel', it could cover a wide range of themes. It might be about a post - apocalyptic world where survivors struggle to rebuild society, and the light novel follows their journey. Or perhaps it's a story set in a magical realm filled with mythical creatures, and the main plot revolves around the protagonist's quest in this enchanted land. There could also be political intrigue, family drama, or exploration of different cultures within the pages of this light novel.
I'm not sure specifically as I haven't played it in detail. But generally, a visual novel often involves a story with characters, plot development, and probably some kind of relationship exploration.
