Killer drones

En was previously a waiter, found by Tessa in a dump just like V, J, and Son. When Son, well, probably went crazy, he was dragged into the basement of the mansion, where he was either turned into a killer drone or lobotomized. He became completely normal when his head was blown off with an Uzi railgun.

Jay was Tessa's best friend when Sin went crazy, and she was there for Tessa and helped her, and Jay later had a lobotomy. After that, she became the head of the killer drones (V, N, and Jay) and later became an ally of Sin.

Vi (may contain errors) - (I think) was somewhere near the basement, broken, she had poor eyesight and was the first to undergo a lobotomy. Later, she helped the son perform a lobotomy on En. Then she became the most bloodthirsty dismantler (or killer), but when Lizzy agreed to be at the concert, she became calmer and sided with En and Uzi.

Tessa - her rather strict parents didn't have time for her, so she brought drones home to communicate and play, during the attack, Sin apparently somehow managed to escape, I don't know.

Doll is a quiet student with dark red eyes and very dark blue hair, she has a solver, Doll takes revenge on the killer drones (V, N and J) for killing her parents, speaks English, she has a button instead of an eye

Lizzie - She has the personality of a typical average, loud schoolgirl, often on her phone, is friends with V, she has pink hair and is friends with many of her classmates

Ted (I didn't even know his name) is an authoritative character, but a rather kind and cheerful guy, a friend of Uzi and many of the class, he has green eyes, wears a cap

This will be Sin's first form, or rather, when Tessa is alive, because otherwise the chat is just really slow :(

Sin looks like a regular drone, except she had, I don't know, scoliosis, grade 4 or even higher? Although only grade 4 is possible, but she's a drone, so whatever. She's dressed like a barmaid, the main antagonist, and she's pretty creepy even when she's not being aggressive.

clarification: Sin doesn't have drones, in fact, she only got Jay as an ally at the end of the series.

Tessa is the only person left on two planets (one had a big explosion, and the other was probably killed by Sin and his drone dismantlers, I don't know). She's 20-30 years old and she's a girl. She has a sword and wears a spacesuit, probably because the air on the planet where the story takes place is toxic. She doesn't have a serious personality.

En is a pretty kind and cheerful dismantler, he is Uzi's best friend, Vi's good friend and one of the only men... and he also used to be Sin's friend and she called him her brother, he was, I don't know, a waiter, probably Jay is a calm drone dismantler who eventually became an ally of Sin, a female drone, although they are not particularly different. She used to be Tessa's best friend and was often with her. Vi is a relatively violent drone dismantler, a friend of En and Uzi, a female drone who used to have poor eyesight and was apparently the first to be brainwashed by Sin.

(for the chat - those who BEFORE had some kind of uniform like En, he has now, I don't know, let's say a robe, a T-shirt and pants)

The worker drone is a humanoid robot. Instead of the part above the mouth, there's a screen where either the eyes or the text would be. Most of them have white hair, and I don't know where they got their hair from. They have cores inside that look like a slightly fleshy iron creature on three legs that can speak and think, but this is the drone's mind, and it can be activated if the body is destroyed or the core is removed. They also live in a base with three protective and huge doors from Khan Dverchenko.

Killer drones (N, J, and V) - look almost like regular drones, but with a tail at the end of which is a syringe with nanite acid (something like sulfuric acid), and their hands can also be replaced with other things (machine guns, swords, saws, lasers, and soap bubbles), they also have iron wings

Solver is a thing that is passed down through generations and is possessed by 4 drones (Uzi's mother, Uzi, Sin, and Doll). It gives 3 things: 1) wings (Uzi has when she uses it), 2) telekinesis (all carriers have it), 3) creating black holes (Sin and Uzi have it).

The planet where the events take place (or Copper 9, I don't know the exact name) has a lot of trash on it, including drone parts. It's in perpetual winter, and at night you can see two planets, one of which looks like Saturn.

Yeah, the whole family.

Uzi is the main character, a schoolgirl of about 14-16 years old, a drone herself, like almost everyone here except Tessa. She has purple eyes, she's friends with En and Vi, she often deflects conversations with the word "bite me," and she created a railgun that shoots... a very, VERY powerful laser.

Khan (I honestly can't remember his name) is Uzi's father, he's about 30-40 years old, he has a mug with an inscription that says something like "best father", he has gray eyes and also has a fake mustache, he's strict in some ways and kind in others

Uzi's mother (I couldn't find her name) - Uzi's mother, very similar to Uzi in character, but unlike her, she's older and she... became the core of the Drone, and as far as I know, she has a solver and because of that, telekinesis, and she also has a pickaxe as a weapon.
