I'm sorry but I have no knowledge of the 'betrays light novel' so I can't tell you its plot. If it follows common themes in light novels, it could be set in a fictional world, and the act of betrayal could be a central point that drives the story forward. Maybe it involves political intrigue, or personal vendettas within a group of characters. But until we have more information, we can't be sure.
As I don't know the exact 'betrays light novel', it's hard to say the plot. However, generally speaking, if it's about betrayal, it might involve complex relationships among characters. For example, a friend might betray another friend for power or love. Or in a more epic story, a hero could be betrayed by someone close and then has to face a great challenge. But again, this is all guesswork without more details about this particular light novel.
It could also be a misunderstanding. Hinata might be framed as a traitor. Some false evidence could be planted that makes Naruto and his friends believe she has betrayed them. This would lead to a lot of drama and conflict in the fanfiction as Naruto struggles with whether to believe Hinata or the evidence against her.
One possible plot could be that Naruto discovers some dark secrets about Konoha's leadership. For example, he might find out that they were involved in unethical experiments in the past. This discovery could make him feel betrayed first, and then lead him to take actions that Konoha sees as betrayal, like refusing to follow orders or even teaming up with an enemy of Konoha who he believes has a more just cause.
One possibility could be a misunderstanding. Maybe Kakashi is framed for something that makes Naruto believe he has betrayed him. For example, an enemy could use a clone of Kakashi to perform a heinous act, and Naruto witnesses it without seeing the full picture.
Well, it could be that Wonder Woman is somehow influenced by a powerful enemy or a mind - controlling device. Maybe she's forced to turn against Batman to protect something she values more, like her own people on Themyscira. Or perhaps there's a misunderstanding between her and Batman, and she misinterprets his actions as a threat to the world.
In this fanfiction, perhaps Percy is influenced by some dark force. This force convinces him that the Olympians are corrupt and need to be overthrown. He then betrays them by stealing important artifacts from Olympus that are crucial for its protection. He might also try to turn the demigods against the Olympians.
One possible reason could be power. Maybe in the fanfic, there's a new source of power that Tsunade wants desperately and Naruto stands in her way to obtain it. So she betrays him to get to that power.
In such a fanfiction, perhaps Hermione could be blackmailed into betraying the Order. Maybe an enemy discovers a deep secret about her family and forces her to give up Order secrets.
It could be that Artemis betrays female Percy out of a sense of duty to the gods' code. Suppose there is a rule among the gods that female Percy has unknowingly broken. Artemis, being a strict adherent to the gods' laws, decides to take action against her. This could involve setting traps or leading her into dangerous situations, all in the name of upholding the divine order.
There are so many light novels that it's difficult to identify a particular one named 'betrays light novel' without additional information. Maybe it's a relatively new or niche light novel. You can try using different search engines and adding more keywords related to the genre or possible author to narrow down your search.
Another aspect could be related to her past or origin. If she has some hidden memories or a secret agenda tied to her existence as the Fem Kyubii, it could lead her to betray Naruto. For example, if there are some dark forces that are controlling or influencing her from her past, she may be forced to turn against Naruto against her will in a sense.
