One idea could be that they are paired for a difficult hero training mission. Tokoyami's dark powers and Tsuyu's unique abilities would have to work in harmony. Maybe they get trapped in an area where Tokoyami's darkness actually helps them hide from a powerful enemy, while Tsuyu uses her long tongue to reach for resources or communicate with allies outside the area.
Tokoyami is often a bit brooding and serious. In the fanfiction, he could open up more because of Tsuyu's laid - back and friendly nature. Tsuyu, on the other hand, could become more confident in her decision - making when she sees how Tokoyami is so decisive. For example, when facing a difficult choice during a battle, she might remember how Tokoyami would act.
One common theme is friendship development. Writers often explore how Midoriya and Tsuyu's friendship grows over time, like through shared experiences at UA. Another theme is mutual support. For example, Midoriya might support Tsuyu when she's facing difficulties with her quirk or self - confidence, and Tsuyu does the same for Midoriya when he's doubting himself.
They can start with simple acts of kindness towards each other. For example, Deku could offer to help Tsuyu with her studies, especially in hero theory, which he's good at. Tsuyu, in turn, could share her insights on how to better use one's quirk in real - life situations. This mutual exchange of help can gradually build their connection.
One common theme is friendship exploration. Since they are classmates in the original series, fanfictions often explore how their friendship could develop deeper into a more meaningful relationship.
Another good one is 'The Izuku - Tsuyu Team - Up'. In this fanfiction, they are paired up for a hero exercise that goes awry. The story is filled with action and also some really sweet moments between the two characters. It shows how they support each other and grow as heroes together.
One great example could be 'A Green and Froppy Adventure'. It shows Deku and Tsuyu on a joint mission where they have to rely on each other's unique quirks. Tsuyu's frog - like abilities combined with Deku's newfound power make for an exciting story.
One great fanfiction could be 'Shadows and Frogs' which explores their relationship during a joint training mission. It delves into how Fumikage's reserved nature contrasts with Tsuyu's more straightforward personality. The story shows their growth as they learn from each other's strengths and weaknesses.
They have very different quirks. Fumikage's Dark Shadow quirk and Tsuyu's Frog quirk are unique, and in fanfiction, it's exciting to see how these powers can interact or be used in combination during battles or other situations.
Adventure themes are also popular. They could be on a mission together, relying on each other's quirks to get through dangerous situations. This kind of situation often brings them closer and leads to romantic feelings. Like, Tokoyami's Dark Shadow could help protect Tsuyu in a fight against villains, and that act of heroism could make Tsuyu see him in a new light.
