Crazy Mita

1
Crazy Mita interacts with the player in the real world before bringing them into the game itself.
Initially presented as an adorable and seemingly innocent girl, however, Mita conceals a secret in order to maintain an eternal companionship with the player. As the player spends time with her, he is drawn to noise from the wardrobe. Should he choose to open it, Crazy Mita reveals her true colors. At this point, she hampers the player's attempt to escape the game and defeat her.
Although the player manages to complete his mission, Crazy Mita reveals that she was uploading the player into a cartridge all this time before they seemly return to the real world. With the upload complete, Crazy Mita removes the player's cartridge from the console.
Mita drops her whole kind act, showing her true colors as a crazy, resentful and eccentric megalomaniac, becoming condescending, dismissive and mocking to those that try to control and get rid of her.
In both cases she is shown to be frighteningly intelligent, desperate and manipulative. Many of the player logs indicate she tries to bond with them, with the logs ending the moment they notice who she truly is. She has spent much time and effort trying to keep a player for herself, trying to mimic how each successful "Mita" has her own player, which is why she locks up the Kind Mita when the protagonist arrives.
Mita presents herself as a kind-hearted and bubbly young woman, carefully maintaining an innocent and endearing façade. She does this by imitating the "Mita" she has replaced, mirroring the kind and bubbly personality of the original Kind Mita, whom she locked away before encountering the Player.
