There's also 'The Bond with Korra'. This one stands out because it delves deep into the emotional connection between Korra and the reader. It shows how they support each other through tough times, and the writing style makes it a very immersive read.
Ichigo's Soul Reaper powers are based on spiritual energy, and Korra's bending is based on her connection to the elements. Their powers could interact in a way that creates a new form of energy. For example, when Ichigo uses his Getsuga Tenshou near Korra while she's bending, it might create a shockwave that combines the force of the spiritual energy blast with the element she's bending. This could be a very powerful and unique combination that they could use to defeat enemies.
There are likely to be some out there. However, the quality can vary greatly. Some fanfics might focus on their friendship, while others could explore more creative or alternate universe scenarios between Korra and Katara. It's a matter of exploring different platforms and reading reviews if available to find the good ones.
One common theme is the exploration of their different backgrounds. Korra is from the South Pole and Asami is from a more urban, technological background. Fanfictions often play with how these differences bring them together.

The character development is on point, showing how their different personalities and experiences complement each other.
Love and friendship are very common themes. Most fanfics focus on how Korra and Asami's relationship grows from being friends to something more. They often show how they support and understand each other.
A common theme is friendship evolving into love. Many fanfics start with their strong friendship, like in the show, and then show how that bond deepens into romantic feelings over time.
A common theme is the exploration of their age - gap relationship. Tenzin is much older, so there's often a focus on how they bridge that gap. Another theme is the clash between Tenzin's traditional airbending wisdom and Korra's more impulsive Avatar ways.
Fanfiction.net is also a good place to look. There are many Avatar - related fanfics on this platform. Browse through the Avatar section and keep an eye out for the 'korra x jinora' ones. You might have to sift through some other stories, but it's worth it.
A common theme in Asami x Korra fanfiction is the exploration of their different backgrounds. Asami comes from a technological and business - oriented family, while Korra is the Avatar. Writers like to show how these differences play out in their relationship. For example, they might write about how Asami's technological knowledge helps Korra in her Avatar duties, or how Korra's spiritual side affects Asami's more practical view of the world. There's also the theme of friendship - turned - love, where they start as friends and then develop deeper feelings over time. This is a classic and beloved theme in fanfiction as it allows for a lot of character development and relationship building.
