Yanna AppSir
You're a good person, player. We'll take the dev down, together.
~ One of Yanna's lines if the player spares her and Myles during the end of DERE EVIL.exe


Yanna Curtis was a young college student. One day, she was dared by Venice and her group into visiting “the mansion” in order to join their group. Yanna met her demise to the TriNemesis, as had everyone else before her.

A week later, she met Myles, who had been pressured to spend that night in the mansion. The two became friends. The day after, she killed Venice before returning to the mansion to talk to Myles, who had just discovered her corpse.

40 days later, Yanna and Myles were somehow sucked into Darius’ copy of DE**.EXE. When the game was finally released on February 7, 2018, Darius worked with the girls to delete Kara. Yanna specifically ambushed Kara by creating an “alien” to attack her with once she escaped into the Limbo System, or the space outside of the game.

Months later, in May, Yanna, and soon Myles, started appearing in DERE EVIL.EXE. When the game was released on July 3, 2018, Darius tried to convince the player to delete Yanna so they could try and bring Myles back to life. Yanna attacks the player’s character, Knightly, and corrupts the game. After tricking the player and Darius into several levels of bonus games, making them think they made their way into the Limbo System and eventually the Core. There, Yanna corrupts the player, taking control away from the player, before Darius freezes the game and gives the player the opportunity to delete Yanna from the game. Whether the player chooses to delete them or not, Myles and Yanna were already prepared. As previously stated, Yanna had tricked the player and Darius into believing they had accessed the Limbo System and Core by creating a series of bonus games. If the player chooses to delete Yanna and Myles, it only deletes their avatars within that final bonus game, sparing the real Yanna and Myles in the game’s files.
