First, define the appearance of the Vritra Gear. Is it a piece of jewelry, a weapon, or something else? For example, it could be a gauntlet that gives the OC special powers. Then, think about how the OC got the gear. Was it inherited, or did they find it by accident?
The OC's personality should be developed in relation to the Vritra Gear. If the gear is powerful but dangerous, the OC might be cautious. They could also be a bit of an outcast because of the gear. In battles, the OC might use the gear's powers in unique ways, like combining it with their own natural abilities or skills they've learned at school.
One idea could be that the OC with the Vritra Gear has to hide its true power at first. Maybe they are new to the school and don't want to draw too much attention. As the story progresses, they gradually reveal their abilities during battles against other supernatural beings.
One common theme is power - up. Since Vritra is a powerful entity in the Highschool DxD universe, many fanfictions focus on the main character getting some sort of power - up related to Vritra. For example, they might inherit Vritra's strength or some of its abilities.
First, decide on the type of youkai your OC will be. Each type has its own characteristics. For example, if it's a tanuki, it could be mischievous and good at shape - shifting. Then, think about their backstory. What led them to the world of Highschool DxD? Maybe they were drawn there by the strange energy or a quest for power. Also, consider their goals and motivations. Are they there to cause trouble, or do they have a noble purpose like protecting the weak?
A unique OC concept. If the original character has a distinct personality, backstory, or power set related to the Boosted Gear, it can make the fanfiction stand out. For example, an OC who has a different way of using the Boosted Gear's abilities compared to the main characters in the original series.
Start with their backstory. Decide where they came from, how they became a dragon slayer. Were they trained by a master? Or did they have a personal vendetta against dragons? This will shape their personality.
