In Highschool DxD, Asia Argento is a sweet and gentle character. Given her kind heart, she could very well be part of the harem in an OC fanfiction. She might be attracted to an OC who shows her kindness and protects her. Xenovia could also be a part of it. She's strong - willed and dedicated to her beliefs. An OC with a different perspective on things might catch her attention. And let's not forget Irina Shidou. Her energetic and somewhat naive nature could lead her to be interested in an OC with an exciting backstory.
A human student with latent supernatural powers could be added. This character could befriend Gasper and his harem, and their discovery of their powers could be a major plot point. They might also cause some jealousy within the harem as they get closer to Gasper.
A heroic knight from a medieval - themed anime. He could be transported to the Highschool DxD world and, due to his chivalrous nature, attract the female characters. He might initially be at odds with the devils but eventually form a bond with the main character and become part of the harem as he adapts to the new world.
A foreign exchange student could be a great addition. She could come from a far - off land with unique powers and a different culture. This would add an interesting dynamic to the harem as she tries to fit in. Another potential character could be a mysterious girl who is actually a powerful supernatural being in disguise. She could initially be an antagonist but then end up falling for the main character. Also, a shy girl who is extremely talented in magic but lacks confidence could be added. The main character could help her gain confidence and she would then become part of the harem.
Yugi himself could be one. His kind and determined nature might make him drawn to an interesting OC. Then there's Tea, who is always friendly and might be attracted to an OC with unique qualities. Joey could also be part of the harem as he's a loyal friend and might see the OC as a great addition to their group. Another potential character could be Mai, with her strong and independent personality, she could be intrigued by an OC's abilities.
A mysterious transfer student could be added. This student could have a hidden power or a special connection to the harem queen's past. For example, she might be from a long - lost clan that has some sort of prophecy related to the harem.

Sif from Asgard is a great candidate. Her loyalty and warrior spirit would contrast well with the OC. And then there's Kitty Pryde.
