Maybe a plot where Giyu and Shinobu are accidentally transported to a parallel dimension where the roles of humans and demons are reversed. They have to figure out how to survive in this strange new world and find a way back home. At first, they are both in shock, but then they start using their skills to adapt. Shinobu uses her intelligence to understand the new rules of this world, and Giyu uses his combat skills to protect them from the 'human - demons'. In the end, they manage to return to their own world with a newfound respect for each other.
A plot could revolve around a mystery illness that is affecting the Demon Slayer Corps. Shinobu, being the expert on poisons and medicine, tries to find a cure. Giyu gets involved when he discovers that some of his comrades are showing symptoms. Together, they suspect that a new type of demon or a hidden enemy within the corps is causing this. They have to investigate, and during this process, they face many challenges and also grow closer as they share their concerns and ideas.
Their relationship can be developed through shared experiences. For example, if they both get injured in a battle and have to rely on each other for survival while waiting for help. This would force them to open up and communicate more, breaking down Giyu's usual stoic exterior and allowing Shinobu to see a more vulnerable side of him.
One idea could be a story where they are forced to team up on a dangerous mission in the demon slayer world. They start off not getting along well due to their different personalities, but as they face challenges together, they gradually understand and respect each other more.
One idea could be a shinobu fanfic set in an alternate universe where she is a detective solving mysteries in a modern city. Another could be a story about her training a new generation of demon slayers and the challenges she faces in that role. Or perhaps a fanfic where she has to team up with her enemies to fight a greater evil that threatens both humans and demons.

How about 'Giyuu x Shinobu: The Jealousy Factor'? This title clearly shows the relationship between the two characters and the key aspect of jealousy. It gives a hint to the readers about what the fanfic might be about, which is the jealousy that could exist in their relationship.
The plot could start with Shinobu noticing Giyuu getting a lot of attention from a new recruit. She starts to feel jealous as she realizes she has feelings for Giyuu. Giyuu, on the other hand, is oblivious to Shinobu's feelings and the new recruit's admiration, which causes more tension.
The plot could involve the reader being a new Demon Slayer. Shinobu takes the reader under her wing to train. They could go on missions together, and the reader slowly discovers Shinobu's kind heart beneath her often - aloof exterior. Along the way, they face various demons and grow closer as friends and comrades.
