Given the name 'the giveaway girl fanfic', it's reasonable to assume that the giveaway girl is the main character. She could be a kind - hearted person who loves to give things away, or she might have a more complex motivation for her giveaways that the story will explore.
I'm not sure specifically as I haven't read it. It could be about a girl who is involved in giveaways, perhaps in a fictional world. Maybe she uses giveaways as a way to interact with others, or it could be part of a larger story about her life and adventures.
It could be an original character created by the fanfic writer. Maybe a young girl who discovers her pyro powers after a strange event.
The main character could be a young girl named Hana. She loves wearing her furisode and has a Pikachu as her first Pokemon. Hana is kind - hearted and determined to become a great Pokemon trainer while still maintaining her traditional style with the furisode.
A girl named Sophia who is a bit of an outcast in her school. Her tongue ticklishness is something that she has always been embarrassed about. But as the fanfic progresses, she meets a group of misfits who accept her for who she is and together they use her unique trait to create a secret club where they have their own special games and activities based on her tongue ticklishness.
Another possibility is a girl named Mia. Mia is an orphan who stumbles upon the tentacle breeding station while running away from some bullies. She finds a new family among the strange creatures in the station and decides to protect it at all costs.
Erza might be an interesting main character for this fanfic. Given her strong will and combat skills, she could incorporate the guitar into her fighting style. For instance, she could use the guitar as a weapon, slashing enemies with the sharp edges of it while also using its music to disrupt their magic.
The main character in the '88 girl story' is presumably the girl it's named after. However, without more information about the story, we can't know anything about her personality, her age, or what she does in the story.
Hermione could be an interesting main character for such a fanfic. Imagine Hermione suddenly being transformed into a cow girl. Her intelligence would be combined with her new cow girl skills. She could use her knowledge of magic to understand the transformation better and at the same time use her cow girl skills, like herding magical creatures in a more efficient way than before.
Obviously, the main character would be the girl named 'sweet cheeks'. She would be the one driving the story forward, whether it's through her relationships, her goals, or her personal growth.
An underdog character who has been at the bottom of the school's hierarchy could be a great main. Maybe she's been bullied or overlooked for a long time. But then she discovers a hidden talent or an ancient martial art technique. With new - found confidence, she decides to challenge the status quo. She has to face many obstacles along the way, including the disbelief of her peers and the resistance from those in power. However, her journey from being a nobody to someone important can be a really engaging story.
