I'm not entirely sure about the specific plot details as I haven't read it thoroughly. But generally, it might revolve around a character's journey to be a loyal and dedicated protector or servant, like a sword is to its wielder. It could involve themes of loyalty, self - discovery, and the challenges that come with trying to fulfill such a role.
The main character in the 'I Tried to Be Her Loyal Sword Novel' is the one with the goal of being the loyal sword. It's likely that this character has certain qualities that drive them towards this loyalty. The other main character is the 'her' in the title, who is the recipient of this loyalty. There could be other important characters as well. For instance, there might be a character from the protagonist's past who has influenced their idea of loyalty. Or there could be a new acquaintance in the story who challenges the protagonist's loyalty in unexpected ways, adding more depth and conflict to the story.
Another one could be 'The Name of the Wind'. It also delves into the journey of a character, much like the protagonist in 'I tried to be a loyal sword novel', with elements of self - discovery and loyalty to certain ideals.
Since I'm not familiar with this novel, it could potentially be about a sword named Cassmire that has some sort of loyalty or special significance. Maybe it's on a quest with its owner, or perhaps it has a role in a grand battle or adventure. But this is all just speculation without having read it.
I'm not very familiar with this specific novel. It might be a relatively niche or new work. Maybe it's about a character's aspiration to be a reliable and steadfast sword, perhaps in a fantasy or historical setting.
You could start with a concept that has broad appeal. For example, a story about human relationships like love, friendship or family. These are themes that people all over the world can relate to.
