I'm not sure exactly when it was released. You might want to check the official publisher's website or some reliable book news sources for the accurate date.
The back story of KH is quite complex and involves a series of events and characters. It all started with a mysterious incident that set the stage for everything that followed.
It depends on the specific context. If you mean in a particular book or series, it could vary greatly. Maybe it's a few hundred pages or several volumes.
Since I have no prior knowledge about what 'kh 358 2' represents, it's impossible to tell the full story. It could be an identifier for a local event, a private initiative, or a specialized item. If you can provide more background, it would be possible to give a proper account.
A 'kh crossover fanfic' is a fan - created work that combines the Kingdom Hearts (KH) universe with elements from other franchises. It could involve characters from KH interacting with characters from, say, Final Fantasy or Disney in new and unique storylines.
One possible fanfiction could be about Roxas and Xion exploring the new worlds in KH3 together. They might face new enemies and challenges while also reminiscing about their past. Their bond could grow stronger as they help each other through difficult situations.
In most cases, the KH light novels are considered canon. They often expand on the existing lore and characters in a way that fits within the established framework of the series.
Character development is a key element. Since Riku is now female, exploring how she develops in this new identity, like her self - discovery journey. Another key element is the relationships. Her relationships with other characters, whether it's friendship or something more complex, are different from the original male Riku's relationships.
Since it's a fanfic related to KH3 and the final twilight, it could be a creative take on the conclusion of the game's story. It might expand on the themes of light and dark that are so prominent in the Kingdom Hearts series. The author could have added new characters or modified the existing ones' personalities. They might have also created new locations within the final twilight setting to make the story more interesting and engaging.
