Megumi Fushiguro is popular as well. His cool and reserved demeanor, along with his powerful cursed technique, attracts a lot of fanfiction authors. They might write about his relationship with other characters, like his unspoken bond with Yuuji, or explore how he further hones his skills in different scenarios.
You could look at characters who have faced similar challenges or have values you hold dear. For example, if you're resilient and always bounce back, maybe Elsa from 'Frozen'. If you're a creative thinker, like Belle from 'Beauty and the Beast'. And if you have a strong sense of justice, like Captain America from the Marvel universe.
Yuji Itadori is often a popular choice. His determination and unique abilities make for interesting time - travel scenarios. He could use his physical strength and Sukuna's power in different ways in the past or future.
Perhaps one character could be a die - hard 'bleach' fan who is really good at the quiz. And the other character could be someone new to the 'bleach' world but is attracted to the first character's knowledge and passion during the quiz. So these two could be the main characters in this 'bleach quiz love story'.
In the 'dream girl quiz story', the main characters might include a protagonist, perhaps a young man who is on a quest to find his dream girl. There could also be the potential dream girls he encounters, each with their own unique personalities. Additionally, there might be friends or family members of the protagonist who play a role in either helping or hindering his search. For example, his best friend could be giving him advice on how to conduct the quiz to find the right girl, or his mother could be sharing her own ideas about what makes a great girl.
I think I'm a bit like Harry Potter because of my sense of adventure and determination. Also, maybe like Hermione for my love of learning and being smart. And like Frodo from The Lord of the Rings for my perseverance in difficult situations.
I think I'd be Harry Potter for his bravery and magical skills. Also, Hermione Granger for her intelligence and determination. And maybe Katniss Everdeen for her strength and survival instincts.
Characters can be developed by their interactions with others. In the fight quiz, they might meet mentors or rivals. For example, a young fighter meets an old veteran who gives him advice on combat. The young fighter can then incorporate this advice into his fighting style during the quiz. Also, rivalries can fuel their growth. If there's another fighter who constantly challenges them, they'll be forced to improve throughout the day - long story.
