Since I don't know the exact 'hako light novel', it could be anything. It could be a love story set in a post - apocalyptic world where the 'hako' is a symbol of hope or a container holding something crucial for the survival of the characters. It could also be a story of self - discovery where the main character is somehow related to the 'hako' and through different experiences, they learn more about themselves and their purpose.
As I don't know the specific 'hako light novel', I can't say for sure. But typically in light novels, there could be a young hero or heroine, perhaps a sidekick or two, and maybe some antagonist characters.
It ends at a specific chapter or volume, but I'm not sure exactly which one. You might have to check online fan forums or manga databases for accurate information.
I'm not entirely sure as I haven't read it in detail. But generally, it might be about some unique characters and their adventures, perhaps with elements of mystery or fantasy given the rather intriguing title.
It depends on how much of the manga's plot was covered in the anime. But typically, start from the next chapter after the final episode of the anime. This ensures you don't miss any new developments.
I'm not entirely sure as I haven't read it. But generally, a light novel with such a title might be about a powerful hero and something related to a 'oharai hako' which could be a special box or container in the context of the story.
The novel form of AO ONI can explore themes and ideas in a more detailed way as it is not restricted by time or animation budget. The anime may have to simplify some aspects to fit into an episodic format. For light novels, they are aimed at a wide range of audiences. They can be more accessible than pure novels as the illustrations help in visualizing the story. And the anime might take some creative liberties compared to the original novel and light novel, for example in character designs or certain plot twists for the sake of visual impact.
The main differences are in the pacing and some minor character developments. The anime might speed up or slow down certain storylines compared to the manga.
