One great 'Muichiro x Reader' fanfiction is 'A Meeting in the Mist'. It beautifully captures Muichiro's somewhat aloof nature while gradually developing a sweet relationship with the reader. The descriptive language used really makes you feel like you're in the Demon Slayer world with them.
The relationship development between Muichiro and the reader has to be believable. It can't be too rushed. A slow - burn, where they gradually get to know each other, understand each other's quirks, and form a deep connection over time is much more appealing. Also, the setting should be in line with the Demon Slayer universe. Whether it's in the Demon Slayer Corps headquarters or on a mission, the details of the world should be well - described.
Muichiro's death in the manga occurs during a particularly intense confrontation. His injuries accumulate, and he ultimately succumbs despite his valiant efforts.
I don't know what 'ts cock' is. It could be a code or a term specific to a certain group or personal jargon. So I can't say what such a story would be about.
There are also some indie authors who write excellent Bella has powers fanfiction. They might not be as well - known, but their creativity shines through. These authors often experiment with different types of powers for Bella, such as the power to heal others. Their stories offer fresh perspectives on the 'Twilight' universe and Bella's role in it.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). They have a vast collection of fanfics, and you can use the search function to specifically look for ones that combine Sephiroth and Game of Thrones. Another option is Fanfiction.net, though their search might be a bit less refined. Just type in 'Sephiroth Game of Thrones' in the search bar and see what comes up.
Jim Lake Jr. from Trollhunters is an obvious choice. His journey as a Trollhunter and his growth throughout the series make him a very dynamic character. In a crossover, seeing him interact with the characters from 3Below, especially with his sense of justice, would be really interesting. Another interesting character would be Aja from 3Below. She is a strong - willed princess who has her own set of skills and knowledge. Her leadership skills and her ability to adapt to new situations could create some great storylines when paired with the Trollhunters.
