Some 'Princess Knight' light novels may be part of a series. In these cases, each volume builds on the previous one, delving deeper into the world - building. For example, we might see the development of different regions within the fictional kingdom and how the princess knight's actions impact them.
There are also some fan - made 'Princess Knight' light novels that expand on the original concept. These might focus more on the relationships the princess knight has, such as her friendships with other knights or her romantic interests. They can offer different perspectives and new storylines.
