One popular theme is the brothers' daily misadventures. Since the Osomatsu San characters are known for getting into all sorts of comical situations in the original work, this often extends to fanfiction. Another theme could be their relationships, not just among themselves but also with other characters they might interact with in the fan - created scenarios. For example, how they deal with new neighbors or strangers in their neighborhood. And of course, there are also fanfictions that explore their dreams and fantasies, like what if they were in a different world or had different superpowers.
How about a crossover with 'Gintama'? Both shows have a great sense of humor. The Osomatsu brothers could find themselves in Edo and get involved in Gintoki's crazy adventures. They might even try to open their own Odd Jobs business, but with their own twist. Or a crossover with a magical girl anime. The brothers could be turned into magical boys by accident and have to save the world while still being their lazy, goofy selves.
First, you need to have a good understanding of the characters. Watch the Osomatsu San anime or read the manga to get a feel for their personalities, likes, and dislikes. Then, come up with an interesting concept. It could be something as simple as the brothers going on a picnic and all the chaos that might happen. Next, create an outline of your story. Decide on the beginning, middle, and end. And don't be afraid to add your own unique twists to the story.
A common theme is romance. Many fanfictions explore a romantic relationship between one of the Osomatsu brothers and the reader. Another theme is friendship. It could be about the reader becoming good friends with the brothers and having fun adventures together. Family - like relationships are also seen, where the reader is sort of adopted into their wacky family.
Begin by brainstorming some unique scenarios that could happen as a result of the crossover. Maybe the Osomatsu - san world has some sort of connection to the other universe you're crossing it with. You could start writing a short introduction that shows the brothers in their normal setting before the crossover occurs. Then, gradually introduce the elements of the other universe. If it's a crossover with a sci - fi world, show how the brothers react to advanced technology, like they're both amazed and a bit scared. Don't be afraid to add humor, as that's a big part of Osomatsu - san.
It could be a new neighbor who is jealous of the little sister's relationship with her brothers. This neighbor might try to drive a wedge between them by spreading rumors or causing trouble. For instance, they could tell the brothers that the little sister doesn't really care about them and is just using them for her own gain.
The little sister could start a club at school that is inspired by the things the brothers do. But she faces some challenges like getting enough members and dealing with a strict teacher. The brothers might try to interfere in their own clumsy way to help her out. It could also be interesting if she has a secret friendship with one of the brothers' rivals and has to keep it a secret from her family.
Sure. One great place to find osomatsu san x reader fanfiction is Archive of Our Own (AO3). There are various stories there with different themes and plotlines.

The plot twists are quite something. There are moments where you think you know what's going to happen, but then the story takes a completely different turn. This keeps you on your toes as you read through the 'cosmic blaster osomatsu san light novel'.
It could be an envious rival. Maybe someone who's always been in the shadow of Osomatsu and his brothers and decides to take matters into their own hands by kidnapping Osomatsu. Another option is a deranged collector. This person might see Osomatsu as a rare item to add to their collection of oddities. Or it could be a vengeful spirit. In a more supernatural setting, a spirit with a grudge against the Matsuno family could kidnap Osomatsu as a form of revenge.
