One possible story could be that Mimiko is bitten by a mysterious vampire one night while walking alone. She then starts to experience strange cravings and enhanced senses. At first, she's terrified, but as time goes on, she begins to embrace her new vampiric nature.
Yes, there might be. There are many fanfic communities out there where such stories could exist. You could try searching on popular fanfic websites like Archive of Our Own or FanFiction.net.
In many Geto and Gojo fanfictions, the theme of trust is crucial. Their trust in each other can be tested in various ways. Another common theme is the exploration of their past. What made them who they are? How did their past experiences shape their relationship? And the theme of growth, both as individuals and in their relationship with each other, is also often seen.
His relationships, especially with other characters like Gojo, are often explored. Fanfics might show the deep friendship they had before Geto's fall and how it deteriorated. It gives more depth to their dynamic.
One of the main themes is the contrast between their personalities. Gojo is more carefree and confident, while Geto has a more brooding and complex nature. Fanfics often explore how these differences affect their relationship. Growth is also a theme. As they face various challenges in fanfics, they grow as characters, both individually and in their relationship with each other. Additionally, the theme of redemption can sometimes be found, especially in fanfics that focus on Geto's character arc.
I really like 'Gojo and Geto: Bonds Beyond'. It explores how their friendship could have developed further if certain events in the original story didn't occur. It's full of emotional moments and great character development. There's also 'The Geto - Gojo Dynamic' which is more of a character study. It analyzes their actions and decisions in relation to each other in a really interesting way.
A great aspect of this fanfiction is the world - building. The Black Blood Brothers universe has a lot of potential for expansion. Writers can create new factions or powers that Jiro and Mimiko have to deal with. This not only makes the story more engaging but also gives a fresh perspective on the original world.
One common theme is growth. Their relationship often serves as a catalyst for personal development for both Jiro and Mimiko. For example, they might learn to be more understanding or brave because of each other.
