Yanna Curtis is a supporting character in Sorority Rites and (in Darius Guerrero’s view) the main antagonist of DERE EVIL.EXE.

Personality

Not much is known about Yanna’s personality except what she tells Myles in their first night together in the mansion. She was a new student at the college, and a self-proclaimed “certified nerd and teenager.” She agreed to do Venice's sorority initiation because she desperately wanted friends and a place to belong. As a ghost however, she became much more independent and confident, able to control and manipulate an entire game world on her own.

Biography

At around June 30, 2014, she was pressured by Venice to take part in her sorority initiation, which meant spending an entire evening at the mansion. While in the mansion, Yanna was killed by the TriNemesis, and her body burned in the mansion fireplace by the sorority. She apparently came close to attacking Venice as a ghost soon after this, but had second thoughts. Her "story" before Sorority Rites can be seen in this AppSir video. This video shows Yanna being bullied by Rose and Venice, her murder in the mansion, and even Dr. Rotschstein's tour of the mansion at the time.

A week later, Yanna met Myles Stone. It wasn’t clear to Yanna why Myles, who was alive at the time, could see her, but suspected that Myles would soon die as she did. The two girls talked about the mansion and the stories surrounding it before Myles fell asleep on the master bed. Later that night, Myles heard Yanna crying somewhere in the mansion, and Yanna explained how she had been killed the week before.

The next morning, Yanna went to Venice’s home, killing Venice to avenge her and Myles’ deaths. Myles arrived at Venice’s home soon after Yanna had killed Venice. Myles ran back to the mansion to discover her own lifeless body still lying on the master bed. Yanna comforted Myles, offering to stay by her as her perpetual friend.

After about 40 days of roaming as ghosts, Myles and Yanna were both somehow sucked into Darius’ copy of DE**.EXE. On February 7, 2018, when DERE.EXE was released, Darius worked with the girls to try to delete Kara. Yanna, specifically, was able to ambush Kara by creating an “alien” to attack her once she escaped the final level.

A few months later, in May, the girls started appearing in certain levels in Darius’ versions of DERE EVIL.EXE. When the game released on July 3, 2018, Darius tried to convince the player to delete Yanna to try to bring Myles back to life. Yanna attacks Knightly, the player character, and defies Darius throughout the game, appearing as a recurring boss and sending her corruptions to attack Knightly many times. Whether the player chooses to delete them or not, Myles and Yanna were already prepared. Yanna had created several games within games so that only their avatars would be deleted, sparing the real Yanna and Myles in the game’s files.
