Another plot could revolve around the backstories of the minor characters in kakegurui. Maybe there could be a fanfic that focuses on a character who was once a top gambler but lost everything due to a conspiracy within the academy, and now they are seeking revenge through a series of elaborate gambles.
One idea could be a fanfic where a new student arrives at Hyakkaou Private Academy with a unique gambling style that no one has seen before, causing chaos and new alliances to form. For example, this new student might use mind - reading techniques during card games, but not in a supernatural way, more like a highly trained psychological skill.
A third plot idea for a kakegurui fanfic could be a crossover with another school - themed anime. Picture the students of Hyakkaou Private Academy having to compete against students from another school known for their own set of extreme challenges. This would bring new dynamics as the different cultures of gambling and competition collide.
Well, consider a crossover with 'Sailor Moon'. The Sailor Scouts could find themselves in the world of Kakegurui and have to participate in the gambling games. Their magical powers might give them an edge, but the mind - games in Kakegurui are different from what they're used to. Another plot could be a crossover with 'Hunter x Hunter'. Gon and Killua could enter Hyakkaou Private Academy for a special gambling tournament. They would use their Nen abilities in unique ways to win the games. A crossover with 'Naruto' is also possible. Naruto and his friends could be in a situation where they have to gamble their ninja skills and knowledge in the Kakegurui - like games.
Another plot could revolve around the characters having premonitions of the events that are going to occur in the quarry. They then have to decide whether to trust these visions and how to act upon them. This could add a whole new layer of suspense and mystery to the story.
One idea could be a time - travel plot. The Backyardigans accidentally find a magical object in the backyard that sends them to different eras in history. They could have to work together to find their way back home while also learning about the different time periods. For example, they might end up in the prehistoric era and have to deal with dinosaurs.
One idea could be a story where one of the dalmatian puppies gets lost during a family outing and has to find its way back home, facing various challenges along the way.
One idea could be exploring the backstory of a minor character in the Bioshock universe. For example, a splicer's journey before they became spliced. It could show how they were once an ordinary citizen of Rapture and what led them to make the fateful decision to use ADAM. Another plot could focus on an alternate timeline where the protagonist makes different choices. Maybe they side with the wrong faction and have to deal with the consequences. A third idea is a story centered around a new type of plasmid that has unexpected effects on the user and how it impacts the power dynamics in Rapture.
Another plot could involve the creation of a female monster. In the original, Victor Frankenstein was hesitant to create a female. A fanfic could explore what would happen if he did. Maybe the two monsters would have a complex relationship, and together they would try to find a place in the world that would accept them.
One idea could be that Batman and Wonder Woman team up to stop an ancient, otherworldly threat that's beyond the capabilities of the Justice League alone. They have to travel to different dimensions and rely on each other's unique skills.
A heatwaves fanfic could center around a young couple. The heatwave makes their living situation difficult, like their apartment has no air conditioning. They have to find creative ways to cool off and in the process, their relationship deepens. They could also get involved in community efforts to help those more affected by the heatwave, such as the elderly or the homeless.
One idea could be exploring the backstories of the other cyborgs in more detail. For example, what was their life like before becoming a cyborg? Another could be a time - travel plot where Cyborg 009 goes back to change a crucial event in the past that affected all the cyborgs. Maybe a story about how they interact with normal humans in a world that is starting to accept them more, and the challenges that come with that.
One idea could be a story about a new rookie firefighter joining Station 19. They face challenges in fitting in with the tight - knit team while also dealing with their own personal fears related to the job. For example, they might be afraid of heights but have to overcome it during a high - rise rescue.
