There might be a group of monster students. For instance, a werewolf who is strong and brave but a bit clumsy at times, a vampire who is elegant but a bit snobbish, and a mermaid (if there is a pool in the school) who is shy but very kind. And of course, there could be a headmaster of the monster school, perhaps an ancient dragon who has a lot of wisdom and strict rules for the school.
Obviously, Sakura is one of the main characters. There could also be a friendly monster teacher to guide her in the new school.
In addition to Sakura, there could be a mischievous imp as a sidekick character. And maybe a centaur who is good at sports and teaches Sakura some unique monster sports. There could also be a ghost who haunts the school library and becomes Sakura's friend when she helps it to solve a long - standing mystery related to the library's origin.
A powerful dragon that guards the school's most precious treasures could be one of the characters. Also, there might be a group of elves who are experts in nature magic and they could be either friends or rivals to Sakura. Another possibility is a half - human, half - phoenix character who has the ability to heal with fire.
Maybe Sakura will make new friends who are monsters. She could learn about different monster cultures and abilities.
A shy boy who also loves to read and he and Sakura bond over their shared love for books. They might form a study group together and support each other in their academic pursuits.
Obviously, Harry Potter himself would be the main character. Hagrid could also be there as he has a great love for magical creatures. There might be new students who are introduced, like a young witch or wizard from a far - off land who has different ideas about magical creatures. And of course, there could be some professors at the creature school who are experts in different types of creatures.
He would surely interact with Lagoona Blue. Since Naruto loves water-based techniques, he might be interested in Lagoona's mermaid - like abilities. Also, he could meet Cleo de Nile. Naruto would probably be amazed by her confidence and the fact that she's a mummy. They could have some really interesting conversations about their different cultures and powers.
Well, Sakura is definitely one of the main characters, since it's about her going to the past.
Since Sakura is going to Suna, she is a main character. As for others, it might include local leaders or inhabitants of Suna. For instance, there could be a wise elder in Suna who gives Sakura advice, or a young adventurer in Suna who becomes Sakura's friend and helps her explore the area. But this all depends on how the fanfiction is written.
Sakura could have interactions with the Weasley family. Ginny Weasley might become her friend and they could have girl - talk about magic and boys. Fred and George could also be part of her story. They might play some pranks on her at first but then become good friends. And don't forget Neville Longbottom. Sakura could help Neville gain more confidence in his magic abilities as they study together in the Hogwarts library.
Sakura, of course. There could also be a wise old wizard who helps her understand the new world she's in.
There could be the prison guards. Some might be cruel and strict, while others could be more sympathetic. Also, other inmates. Maybe an older, experienced inmate who becomes a mentor - like figure to Sakura.
