Power and growth are common themes. Since Sacred Gears are powerful tools, many fanfictions focus on how the characters develop their powers, like in 'Sacred Gear Ascension' where the protagonist constantly tries to ascend the power levels of his Sacred Gear. Another theme is competition, as seen in 'Sacred Gear Showdown' where characters compete using their Sacred Gears.
One of the common themes is identity. Characters often struggle with how their Sacred Gears define them or change their identity. For example, in some fanfictions, a character with a 'dark' Sacred Gear has to come to terms with that. Also, friendship and teamwork are themes. In 'Team Sacred Gear', the characters have to work together, using their different Sacred Gears to overcome challenges. And of course, the theme of discovery is there too, as new Sacred Gears and their abilities are constantly being discovered in these fanfictions.
Sure. 'A New Sacred Gear' is quite interesting. It explores a new type of Sacred Gear with unique abilities that the main character discovers. Another one is 'Sacred Gear Evolution' which focuses on how the main character's Sacred Gear evolves in unexpected ways, leading to exciting battles and character development.
Well, an interesting plot could be an OC with a Sacred Gear that gives the ability to transform into any mythical creature. The story could be about the OC trying to keep this power a secret while also using it to protect their friends from various threats in the Highschool DxD universe. Maybe there's a group that wants to steal the Sacred Gear for their own evil purposes, and the OC has to fight them off. Also, a plot could involve an OC's Sacred Gear being a key to an ancient treasure that has the power to change the balance of power between the three factions in the DxD world.
Romance is a huge theme as well. It could be between a Shinto - inspired character and one of the main characters from Highschool DxD. For example, a love story between a kitsune (a common Shinto - related creature in fanfictions) and Issei. The cultural differences between Shinto and the other elements in the story can add an interesting dynamic to the romantic relationships.
One common theme is her growth and development. Since she is a strong character in the series, fanfictions often explore how she can become even more powerful or gain new abilities. Another theme is relationships. This could be her relationships with other characters from the show, like forming new friendships or even romantic relationships.
Another theme is her growth in power. Many fanfictions explore how Asia becomes stronger and how that affects her relationships with other characters like Issei. For example, in some stories, as she gains power, she also gains more confidence and is able to stand up for herself more. It's really interesting to see how her character develops in different ways in these fan - created stories.
One common theme is power. Ophis being a very powerful character, many fanfictions explore how her power is perceived and used in different situations within the high school setting.
One common theme is family loyalty. Since the Sitri family is an important part of the Highschool DxD universe, many fanfictions explore the bonds and loyalty within the family. For example, a Sitri character might go to great lengths to protect their family's honor or secrets.
One common theme is power - up. Siegfried is often depicted as getting stronger or unlocking new abilities. This ties in with the overall power - fantasy aspect of the Highschool DxD universe.
Power - up themes are common. The Juggernaut is a very powerful entity in the Highschool DxD universe in fanfictions. So often the stories revolve around the protagonist either obtaining Juggernaut - like powers or using Juggernaut powers in new and exciting ways.
