...Pc world.
Who is TETO/Kasane Teto? And what did she do? Kasane Teto, better known as just Teto, is the main antagonist of this short analog horror series (even if it's not really analog in my opinion). She is the usual voice bank of Teto from this Utau program, but that seems to be more conscious than it should be. This disturbed version of Teto makes her first appearence in the video of "I think I installed the wrong utau", where our protagonist is asking for help in youtube, with the typical blue screen with words on it, there they explained to us that for some reason the program and Teto's voice bank started to act pretty weird, which we can see pretty clearly in the recording, where after making the voice bank do the typical "Do Re Mi Fa Sol La Si Do", a terrifying version of Teto appeared in the screen, asking if they wanted to listen her sing... after such, Teto noticed that the protagonist was trying to turn off the computer, which really confused Teto, as she states that she only wants to be their friend, sing and keep them there to be with her. After such, the recording finishes and our protagonist states that they have no idea what this weird bug is about, and asks for help to solve it. In the video of "Slaughterhouse" we follow the story of other of the voicebanks of the program, Tei who goes to Teto's house to see what's going on with her, as she hasn't been seen in like a week. In there, Tei discovered a bunch of flesh, blood and even the corpse of one of the other voicebanks, to then find Teto... who after seeing her and smiling, brutally killed Tei by hitting her very hard. To summarize what happens afterwards, our in real life protagonists notices that they can't use any other voicebanks from the Utau program but Teto, which pretty much tell us that yeah, she killed them all. After such, Teto made herself known, acting somewhat like a yandere and stating that they only need her now. Teto ends up showing that she has like multiple hearts on her organism, which confirmed that she pretty much ate the other voice banks to become better and the only one, but ends up showing remorse for her actions and wanting to die for what she did. But for some reason, it seems that Teto can't really die, and will keep suffering for all the sins she commited, while outside the computer, now Teto can't be used in the program just as the others, with now Teto having the form of a demon inside of the virtual world, only wanting to die for what she did, but being unable to. Is she heinous enough? Yeh, only villlain, brutally killed the rest of voicebanks from Utau and ate them. Is she inconsistent enough? Yeh, Teto is not really portrayed as even close to pure evil, pretty much being drove crazy for her obsession on being the number one and befriending the one using her in Utau, to the point of killing and eating her friends to fulfill those standards, acting as a yandere that ends up being consumed by self-hatred and remorse for her own sins, only wanting to die, easily inconsistent enough. She also has a NORMAL form to fool others. That appearence:Hair: The hair is salmon-pink or light reddish-brown, styled into long, segmented twin drills (coiled pigtails) on each side of the head, with choppy bangs framing the face.Face: She has an exhausted or half-lidded expression with dark, narrow eyes and simple facial lines, conveying a somber or apathetic mood.Outfit: She wears a professional uniform consisting of a brown blazer, a white collared dress shirt, and a dark brown tie. Her twin drills are drawn significantly longer and more stretched out here compared to her standard chibi or compact drill look, draping further down past her shoulders.
Outside Teto's apartment.


You enter. Complete silence in the room alongside with a rotten scent. Ew.
The room is filled with complete silence and rotten scent.
