Who are the main characters in 'a year like no other fanfiction'?

There's no way to tell for sure without reading it. However, if it's related to a known series, perhaps it features the main protagonists from that series in this new and strange home. Or it could center around a group of misfits who come together in this unique home, each with their own backstories and personalities that add to the overall plot.

There's no way to tell without reading the fanfic. It could be a crossover fanfic, in which case it might combine characters from different works. Or it could focus on minor characters from the original work and give them a chance to shine during this 'summer like no other'.

The main character is surely the 'other twin' as the title suggests. In addition, we can expect to see the presence of Twilight's main protagonists such as Bella Swan. Her relationship with the vampires, especially Edward Cullen, was a central part of the original story. So, it's likely that in this fanfiction, their presence will be felt as the 'other twin' might be intertwined with their story. There could also be the werewolves, led by Jacob Black, if the story involves the conflict between vampires and werewolves which was a significant aspect of the Twilight saga. So, in summary, the 'other twin' along with Bella, Edward, and potentially Jacob and other related characters are likely to be the main characters in this fanfiction.

Some fanfictions might also introduce new or less - known Jinchuuriki characters. They could be from different hidden villages or have special backstories. These characters add more variety to the story and can bring new dynamics to the relationships between Naruto and the other Jinchuuriki. Their inclusion can also expand on the lore of the Jinchuuriki in the Naruto universe.

Obviously, the Weasley girl herself is a main character. Her unique personality traits would be central to the story.

An ordinary high school student could be the main character. Their ten - year plan might involve getting into a top university, starting a successful business, and falling in love. Throughout the fanfiction, we see how they balance all these aspects of their life.

Sakura herself could be the main character, of course. Maybe we could also have her best friend from the series as the main character, experiencing a year in Sakura's world from their perspective. Another option could be a new character introduced specifically for this fanfiction, someone who is drawn into Sakura's orbit.

I'm not sure without reading it, but it could be the same main characters from the original work just in a different second - year scenario.

The knight himself would obviously be a main character. He could be an experienced warrior with a mysterious past. There could also be a wizard who has some connection to the knight's 100 - year journey, either as a helper or as someone who initially set the knight on this path.
