One possible scenario in a Naruto and Riza Hawkeye fanfiction could be a dimension - hopping adventure. Naruto, with his boundless energy and ninja skills, could end up in the world of Fullmetal Alchemist where Riza Hawkeye resides. Riza, being the skilled sharpshooter she is, might initially be suspicious of Naruto. But as they face common enemies, perhaps some alchemist - turned - villains who are after a powerful chakra - based artifact, they start to work together. Naruto's Rasengan and Riza's precise shooting could make for some amazing battle scenes.
A fanfiction could also focus on a training arc. Naruto could train Riza in chakra control, which she could then use to enhance her shooting accuracy even further. In return, Riza could train Naruto in marksmanship, which could be a useful skill for him in certain situations. This could lead to a friendly competition between them, with both of them constantly trying to outdo each other in their respective skills while also growing as individuals and friends.
The plot is crucial. It could be a story that fills in the gaps in the original series, like their time before they became so well - known in the story. Or it could be an alternate universe where their relationship develops in a different way, but still in a way that feels believable and engaging.
