In many light novels, the plot unfolds gradually as the story progresses. It might start with introducing the main character, Iroha Isshiki, and their situation. Then, there could be a series of events that lead to a change in their life. This could be something like a new discovery, a meeting with an important person, or a problem that they need to solve. If there are other elements such as a love interest, it would add another layer to the plot. However, without actually reading the 'iroha isshiki light novel', we can only speculate about the possible plot elements.
One of the main themes is self - discovery. The characters often struggle with understanding their true selves. Another theme could be relationships, like the complex interactions between the main characters.
