One possible plot could be that Usagi is in a bit of trouble, like being chased by a youma. Sailor Venus, being the first to show up, saves her. Then, they start to wonder about each other's identities. Maybe Venus gives Usagi some clues about the Sailor Guardians without fully revealing herself. This could lead to Usagi being more curious and starting her own investigation.
In this fanfiction scenario, it could start with Usagi lost in a new part of the city. Sailor Venus comes across her. Venus is initially a bit guarded but realizes Usagi is harmless. They start talking and find out they have a lot in common, like their love for cute things. This encounter could be the catalyst for Usagi to start her journey as a Sailor Guardian sooner. Maybe Venus takes her to a secret place where she shows Usagi some basic self - defense moves that later help Usagi when she faces her first real enemy.
Their relationship could develop quickly. Since Venus is often seen as a leader - type, she might take Usagi under her wing. She'd protect Usagi and start teaching her about the world of Sailor Guardians. Usagi, in turn, would look up to Venus and be inspired by her confidence.
They could start as enemies. Kunzite is a powerful minion of the Dark Kingdom, and Sailor Venus is a Sailor Guardian. Their first encounter might be intense, full of magical attacks and defenses. But as the story progresses, they find out that there is a third, more powerful enemy emerging that threatens both their worlds. This forces them to work together, at least temporarily.

Well, perhaps it could be a story where Beryl is cursed and Usagi has to find a way to break the curse. Usagi, with her compassion, feels that she can't just leave Beryl in this state. She embarks on a journey, using her Sailor Moon powers and the help of her friends. Along the way, she discovers more about Beryl's past and the reasons behind the curse. This knowledge helps her to finally break the curse, and in the end, Beryl is so grateful that she becomes an unexpected ally to Usagi and the Sailor Guardians.

One possible scenario in a Seiya and Usagi fanfiction could be that Seiya, being a strong and confident character, helps Usagi face a new and particularly difficult enemy. Seiya's different approach to fighting compared to the Sailor Scouts might offer a fresh perspective to Usagi, leading to her growth as a Sailor Moon. They could start off as rivals in a sense, but gradually develop a deep understanding and friendship that could potentially turn into something more romantic over time.
One possible fanfiction could be about a redemption arc for Beryl. In this story, Beryl, who has always been an enemy to Usagi, starts to see the error of her ways. Maybe she gets a glimpse of Usagi's pure heart and kindness that she never noticed before. As a result, she begins to question her own actions and motives. This could lead to a series of events where she tries to make amends with Usagi and the other Sailor Guardians. They are initially skeptical, but Usagi, being the kind - hearted protagonist, decides to give Beryl a chance. This creates a new dynamic in the Sailor Moon universe where they have to learn to work together.
