I'm not sure specifically as it depends on the author's imagination. It could involve a story where Tougou, for some dark or convoluted reasons, abducts a character from Osomatsu. Maybe there's a power struggle or some personal vendetta driving the kidnapping in the fictional plot.
One popular theme is the brothers' daily life adventures. They get into all sorts of comical situations in modern settings. Another theme could be their relationships with other characters from the Osomatsu - san universe. For example, how they interact with Totoko or Chibita. And sometimes, there are themes related to their dreams and aspirations, which can be quite interesting as they often have wild and unrealistic dreams.
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.
The main characters are the six Matsuno brothers: Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu. Each of them has their own distinct personality.
One common theme is friendship. Since they are brothers, a lot of fanfics explore the deep bond of their friendship. Another theme could be growth, showing how they grow together and influence each other.
In the Osomatsu San Visual Novel, a major feature is the multiple branching story paths. This allows players to experience different scenarios based on their choices. The game also incorporates elements from the anime, such as the familiar setting and the comical situations the characters get into. It's a great way for fans to further explore the Osomatsu San universe.
A common theme is brotherly love. Their relationship as brothers is often explored in different ways, whether it's a deep, emotional bond or a more light - hearted, teasing kind of love.
You can start by looking on fanfiction websites such as Archive of Our Own (AO3). It has a large collection of osomatsu fanfics with different ratings and themes. Another option is FanFiction.net, which also has a decent number of works related to Osomatsu - san.
Kochikame Osomatsu light novels are unique because of their ability to blend different genres. They can be comical one moment with slapstick humor and then suddenly shift to a more emotional or thought - provoking storyline. This versatility keeps the readers engaged. Also, the way the novels interact with the existing Kochikame Osomatsu franchise, such as building on the lore or providing new perspectives on familiar events, makes them stand out. The art style, if there are illustrations in the light novels, may also have its own charm, with detailed and expressive drawings that enhance the overall reading experience.
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.
