Your OC could be a transfer student from a far - off place with a different understanding of Alices. They might struggle to fit in at first but then use their unique perspective to solve a big problem at the school. For example, if there's a conflict between different groups of students with different Alices, the OC could find a way to bring them together through their outsider view.
Perhaps the OC has an alice that is related to time manipulation. They could accidentally get stuck in a time loop in the school and have to figure out how to break free while also dealing with the everyday challenges of school life, like making friends and dealing with strict teachers. This would add an exciting and mysterious element to the fanfic.
One idea could be an OC who has a special talent for music and uses it to soothe the children at the babysitting club. For example, when the kids are having a hard time going to sleep, the OC plays a soft lullaby on their guitar.
One interesting concept could be an OC who has a unique and powerful alice that no one has seen before. For example, an alice that can control time in a very specific way, like only being able to freeze time for inanimate objects. This would create a lot of unique situations in the Gakuen Alice setting.
One idea could be that the OC is a new student at Gakuen Alice with a very unique and powerful Alice ability. Natsume, being initially aloof, gradually warms up to the OC as they are paired up for a special project at school. Their relationship starts to develop as they face various challenges together, like dealing with the strict rules of the school and the jealousy of other students.
One interesting storyline could be about a new student at Gakuen Alice who has a very unique and powerful alice that no one has seen before. This new student then has to navigate through the complex social structure of the school while also hiding the true extent of their power.
One idea could be exploring a mystery within the school that involves a long - lost secret society. Maybe the tanteidan discovers ancient artifacts hidden in the school grounds that have some sort of magical or historical significance.
One idea could be creating an OC who is a transfer student with a mysterious past related to the babysitting club. For example, the OC's family might have a connection to the school that is slowly revealed. Another idea is an OC with a unique talent, like being able to communicate with animals, which could add an interesting dynamic to the babysitting situations. A third idea could be an OC who has a different cultural background and introduces new games and traditions to the kids in the club.
One idea could be that Alice finds herself in the Underground and has to navigate through the different areas using her unique sense of wonder. Maybe she befriends some of the monsters like Toriel and they go on an adventure together to find a way out for her.
One idea could be that Alice returns to Wonderland as an adult and has to deal with new, more complex riddles and challenges that are related to the grown - up world she now knows. For example, the Queen of Hearts might be having a 'tax collection' problem in her kingdom and Alice has to use her real - world knowledge of economics to solve it.
Another plot could involve new characters being introduced into the Borderland. These new characters could have unique abilities or knowledge that either helps or hinders the main characters in their struggle to survive. Maybe they know a secret about the origin of the Borderland that could change everything.
One idea could be a story about a new student arriving at Equestria Gakuen. This new character could be from a different part of Equestria and have to adjust to the unique culture and classes at the school. For example, if they're from a more rural area and come to a school in a big city in Equestria. Another idea is a fanfic centered around a school competition. Different groups of students form teams to compete in various magical and non - magical events, and there are lots of rivalries and friendships formed along the way.
