Perhaps a story where they get lost in a strange city. They have to figure out how to get back home while also dealing with their own insecurities and growing closer as a result. Kido could use her leadership skills and Kano his ability to deceive (in a good way, like tricking bad guys) to get through difficulties.
One idea could be that they go on an adventure together in a magical world. They might face various challenges and have to rely on each other's unique abilities to succeed.
One common theme is friendship development. Since they have different personalities, seeing how their friendship grows is a popular topic. For example, in many fanfics, they start as acquaintances and gradually become close friends.
One popular kano x kido fanfic is 'The Meeting of Minds'. It delves into their relationship in a really interesting way, exploring how their different personalities interact. Another one could be 'Shared Moments' which focuses on their adventures together and how they support each other through various challenges.
First, understand the characters well. Know their personalities, strengths, and weaknesses. For example, Kido is often seen as a strong leader, so make sure to incorporate that in the story. Then, come up with an engaging plot. It could be something simple like them spending a day together and learning new things about each other.
One theme could be trust. Since they are part of the Mekakucity Actors, they need to trust each other with their secrets and powers. A fanfiction could explore how they build that trust over time.
One common theme is the exploration of their unspoken feelings. Since they both have complex personalities in the Kagerou Project, fanfictions often focus on how they might be hiding their true emotions for each other.
One great Kagerou Project Kido x Kano fanfiction is 'The Unspoken Bond'. It delves deep into their complex relationship, exploring how their past experiences in the Kagerou Project world have shaped their connection. The story has some really emotional moments where you can feel the tension and the unspoken feelings between them.
A fanfiction might explore a scenario where Kido and Kano have to work together to face a new threat in Mekakucity. Kido's calm and collected nature could complement Kano's more mischievous but also resourceful personality. They might start off bickering but as the situation gets more serious, they realize how much they rely on each other and develop a newfound respect.
One idea could be a crossover where Naruto's world and the world of X - 23 from the X - Men collide. Maybe X - 23 is on a mission and accidentally ends up in the Hidden Leaf Village. She has to learn to adapt to this new place with its different culture and ninja ways. Naruto could be intrigued by her and her abilities, and they could team up to face a common enemy.
One idea could be a story where Spiderman has to team up with his greatest enemies to fight a new, more powerful threat from outer space. This would force him to put aside his differences and find common ground with the likes of Doctor Octopus and Green Goblin.
One idea could be a time - travel plot where they end up in a different era and have to adapt together. Another could be a mystery - solving adventure where they team up to figure out a strange occurrence in their fictional world.
