One common theme could be friendship. Their relationship might be explored in terms of how they support each other through different situations. Another theme could be growth, like how they help each other to develop as individuals.
Often, there are themes of loyalty and trust. In fanfiction, the bond between kuri kounosuke and nishimura hiroyuki might be depicted as unbreakable. They could face challenges together, and their loyalty to each other is what helps them overcome. Also, there may be themes of shared dreams or goals. Maybe they are working towards a common objective in the story, and their relationship is strengthened in the process. It could be something related to their careers or a personal project that they are both passionate about.
There might be themes related to discovery as well. This could be self - discovery, where through their relationship, they learn more about themselves. For example, kuri kounosuke might discover a new side of himself because of his interactions with nishimura hiroyuki. Or it could be discovery about the world around them. Maybe they explore new places or concepts together, and this enriches their relationship. And of course, there could be themes of love, whether it's platonic love or something more romantic, which is often a central focus in fanfiction.

Another good one is 'Under the Cherry Blossoms with Kounosuke'. It's set in a beautiful Japanese - inspired backdrop. The story progresses with the two characters gradually growing closer, and the descriptions of their time together under the cherry blossoms are really vivid.
Some Tumblr blogs are dedicated to sharing fanfictions. You can search for tags related to 'kounosuke x reader' on Tumblr, and you might come across some great fan - made stories that way.
One of the common themes is growth. In these fanfictions, both 707 and Yoosung tend to grow as individuals while also growing closer to each other. It could be in terms of dealing with their past traumas or just becoming better versions of themselves. And also, the theme of discovery, as they discover new things about each other that they didn't know before, which adds to the depth of their relationship.
Well, a frequent theme is the clash of cultures. The shinobi culture from Naruto and the more post - apocalyptic, tribal culture in The 100. Also, friendship and loyalty are common. Characters from both universes have to learn to trust and work with each other, and this forms the basis of many fanfictions.
Often, adventure is a common theme. They could be on a quest together, facing obstacles and enemies along the way. Love or romance might also be a theme, although it depends on the interpretation of the writer. In some fanfictions, they might be in a romantic relationship, while in others, it could be more of a platonic bond with a hint of unspoken feelings.
A prevalent theme in Sofia x Fanfiction is magic. Since Sofia is in a magical world, fanfictions usually explore different aspects of magic, like new spells or magical creatures.

They could explore the origins of those elements or how the characters could better deal with them. Also, family themes are quite common. Given that family is a big part of Supernatural, fanfictions might delve deeper into the Winchester family's dynamics in the context of 12x13.
Common themes could include friendship, adventure, or overcoming challenges. If 'the rider' and 'will' are in a fantasy setting, magic and quests might be common themes as well.
