One idea could be creating a new character who is a transfer student with a unique power. For example, a character who can manipulate time in the Highschool DxD universe. This could lead to all sorts of interesting plot twists, like changing the outcome of battles or getting a peek into the past of the main characters.
A cool plot might involve the Si Sitri character forming an unexpected alliance with other factions in the Highschool DxD universe.

One popular plotline is the self - insert character gradually building relationships with different members of the harem. For example, they might start by befriending a few characters and then over time, romantic feelings develop.

Another interesting concept is an SI OC who is a transfer student from a different supernatural realm. They bring with them their own set of customs and powers that are completely new to the characters in Highschool DxD. This could lead to some really fun cultural clashes and power exchanges.
