Kureiji Ollie's human counterpart from a parallel universe. Olivia is fully human with no signs of zombification, with mostly long red hair and red eyes, and is well-dressed. In contrast to Ollie, Olivia is demure and soft-spoken, prefers peaceful endeavors, and is afraid of violence.
Oddly enough, whenever Ollie "summons" Olivia to play the game for her, Olivia will usually manage to get something that Ollie actually wants (such as getting a legendary item from Apex Legends's loot boxes), which leads into Ollie instantly "sending her back" out of jealousy.
She's essentially an alter-ego created to demonstrate Ollie's voice acting skill, similar to Kurokami Fubuki.
