Kirito and Suguha must be cousins with Shun/Yun and his siblings

There must only be six people from SAO to go into OSO three of them must be Kirito, Asuna, and Klein the other three are up to you

The enemy that they must defeat/stop must be someone from the SAO players' past ( like PoH etc...)


You can make Kirito a female in game like Shun is as Yun or Kirito has always been a female
