Since I don't know the exact 'ghost girl novel', it's hard to say. But surely there would be the ghost girl herself. There might also be a character who discovers her, like a young boy or girl who is curious or brave enough to interact with the supernatural.
Most likely, the main character is the ghost girl herself. She could be a lonely spirit with her own story to tell.
Well, without more information about the 'Ghost Ship Girl Story', we can only speculate. The girl is the central figure, no doubt. But there could be antagonists too. It could be an evil spirit that haunts the ship and tries to prevent the girl from uncovering the truth. There might also be a helpful spirit, perhaps a former crew member who guides the girl through the maze - like corridors of the ship. And perhaps there's a character from the girl's own world, like a friend or a family member who she is trying to get back to, and this longing drives her actions on the ghost ship.
The two main characters seem to be the ghost and the girl. However, in a Mayakashi - related story, there could be other characters such as a wise old hermit who lives near the Mayakashi area and has knowledge about the ghost. Or there could be other spirits or creatures that are part of the same supernatural world as the ghost and might interact with the girl during the story.
From the title 'ghost meets girl a shiranui story', it's evident that the two main characters are a ghost and a girl. The 'Shiranui' might be something that affects their relationship or the events in the story. It could be a third character, or it could be a concept that is central to the story's setting. For example, if Shiranui is a place, it could be where the ghost and the girl meet. But without more information, we can only assume that the ghost and the girl are the primary characters.
The main characters are Danny and the Ghost Girl. Danny, as the half - ghost, has his regular battles with ghosts and his school life to balance, and the Ghost Girl enters his world and shakes things up. She could be a friendly ghost trying to help Danny, or she could be a more mysterious figure with her own agenda. Additionally, antagonists from the Danny Phantom universe like Vlad Masters might also show up in some fanfictions related to the Ghost Girl, creating more conflict and drama in the story.
Obviously, the main characters are the ghost and the girl.
Since I don't know the exact story, the main characters are likely the ghost and the girl. And perhaps there's a character named Shiranui, who could be another important figure, maybe a guide or a source of knowledge in the story.
The title implies that the main characters are a ghost and a girl. The mention of'mayakashi' might be related to the nature of the ghost or it could be another character. If it's a Japanese - inspired story, the mayakashi could be a special type of spirit with its own characteristics that interact with the ghost and the girl.
There's also Rebecca. She is Enid's friend and they share a lot of experiences together throughout the novel.
I don't know as there's not enough information. It could be a young girl who is sensitive to the supernatural, or a group of friends who stumble upon a haunted place.
