Maybe it's a jealous acquaintance. If Kagami is really good at something, like she's a star in a particular activity, someone who is jealous of her success might set up a situation where she gets hurt. For instance, they could tamper with her equipment in a way that causes her to have an accident.
I'm not sure specifically as I haven't read it. But generally, a fanfic about 'tsurugi' might be centered around the character Tsurugi in a particular fictional universe. It could involve his adventures, relationships, or growth. Maybe 'cloud' is related to a setting or another element in the story.
I'm not entirely sure as I haven't read it specifically. But generally, it could be about a story that involves a cane (tsue) and a sword (tsurugi) within the context of the 'wistoria' world. Maybe it's an adventure story where these two items play important roles.
One idea could be a crossover where a character from the Harry Potter world discovers the Kusanagi no Tsurugi. Maybe Harry himself stumbles upon it during a magical journey outside of Hogwarts. The sword's magic could interact with his own magic in unexpected ways.
I haven't read it myself, so I can't really judge. However, if the author is able to build a good story around Naruto having this special 'first tsurugi', it might be great. For example, if they explore how it changes Naruto's abilities or his relationships with other characters in the Naruto universe. But on the other hand, it could also be poorly written, with a weak plot or uninteresting character development. So it really depends on the writing skills of the author.
A frequent theme is probably growth. Both characters might grow individually and together in the fanfiction. For example, they could learn from each other's strengths and weaknesses. Also, the theme of support is common. They support each other through tough times in the story.
Adventure - based themes are also quite common. They go on adventures together and during these adventures, their relationship blossoms. This could be in a fantasy setting, a sci - fi world, or even just in their normal day - to - day lives but with some exciting events thrown in. Their shared experiences during these adventures strengthen their bond and are often a central part of the story.
Since I have no information about this novel, I can't say who the main characters are. But typically in a novel with elements like 'tsue' (cane) and 'tsurugi' (sword), the main characters could be warriors or adventurers who are related to these items. Maybe there's a hero who wields the sword and an old sage with the cane, but this is just speculation.
There's a fanfic called 'Kagami and Marinette: Friendship's Path'. This one focuses on their friendship development. It starts with small interactions and gradually builds up to them having a strong bond. It shows how they support each other through tough times, like when Marinette is having trouble with her love life and Kagami is dealing with family expectations. It's a heartwarming read.
