In the past, Kyouko loves to reside at the human world (Mitakihara to be exact), but she was captured into slavery at another universe at the early age of 5 years old (human age). After turning 15 human years, she grants her wish to Kyubey for freedom and manage to flee to the human world. When staying at Hanshin Republic, a resort island made by human hands and artificial resources, Kyouko tries to defeat a "Virus Witch", but her reckless actions caused the whole island to destroy itself. This Kyouko is a misfit reject to the Puella Magi community, especially "The Others". This is the kind of verse where Puella Magi and Bokurano circumstances hold, so these "children" are still not capable of being legit warriors and can do mistakes.
Kyouko Sakura does not have a good education, so her language is a bit broken, but still easy to understand. Unlike the average Puella Magi Kyouko, this one can also use her were-cat abilities of hearing and night vision, but she has a weak spot for cat nip and fish/seafood. On the rare cases, her cat instincts will make her somewhat lazy too if you give her a comfy couch or bed to sleep. She has a distant "universal" connection with a alternative herself, but as a different person named "Morgiana"....
Kyouko had no direct memory of her family members, except that she is Japanese with a Japanese name and some sort of other racial DNA thanks to her unique red hair and ruby-amber eyes. She was recruited by the Chinese stage performing troupe at childhood and been on the performing act as the main character, the "Monkey King". If done her hair right, she makes a good gender mistake for a male!
She has a unique taste for certain individuals, especially the "people in black coats". Before her 14th birthday, she asks the Trope for her leave, and they can not refuse the request despite heartbroken feelings. She takes her trip ilegally via a cargo ship with some food in stock. So at the age of 14, she makes herself at home on England as a orphan child in "rags" and learned to pickpocket.
Her acrobatic talents proved useful when escaping from drastic situations. However, it seems a few "monsters" had taken an interest on Kyouko!
She will travel to other words to seek out new discoveries, but who knows if her destiney was mroe than just a orphan performer... The costume shown in pictures like above was one of her custom-made "performer's" dress that she will use on later parts of an RP/story.
This verse is created to fit in with any verse setting taking place on early-alternative 20th century where demon hunting was a thing, perfect for any D.Gray-Man, Black Butler, or Chrono Crusade universe. This information can be altered.
The Girl of the Black River and the Dark Warrior with Blood
Kyouko Sakura had lost her family due to a wish from the fairies and learns to use her own magic for herself. At night, she isolates from everyone else while hunting alone, but by day she was either at the park or hitching in some stolen change to play a game of Dog Dug Reinforcement. Kyouko was first invited to play the game by a player named Mirai Kurokawa who was facing a "bonus stage", where it would require two people working together on their hardcore boss track. Kyouko had only met her once at the arcade, but eventually she and Mirai will return.
On civilian life, Kyouko was netural to everyone, though a bit sarcastic at times, but mostly she will not insult anybody at all. At night as a magical girl, she was ruthless and won't stand in her way until she gets what she wants. She would tease any girl into a fight weapon against weapon. Her encounter with "Duskmon" had broke her magic and illusions, making her magical powers useless for a while, but it also prevents her from fogging her Soul Gem as long she doesn't "despair".
This is the Kyouko fit in to the Digimon universe with her magic being "cut off" while there are mysteries that she want to solve herself... This Mirai character and the Duskmon character, which the spoileric-informatin can be found here.
Sacred Gem University
Set in a alternative universe, Kyouko Sakura and Sayaka Miki were close friends who decide to enroll at a special university under Sayaka's application and "skill", and can accept one more person to be her "partner". Unlike most educational universities, this one sets in a fatnasy-like barrier where students can freely do what they want and wish and still can get a good reward out of it. Sayaka has a gift that makes her followers listen to her commands and convert the masculine ways into something more feminine. With her collection of dresses and materials, she can be a nurse, maid, or care-taker if the assignment calls for. Kyouko would ratter care for her children and pets, but combine with Sayaka would mean "serious business"!
Take note that this verse can go in "cute girls doing cute things" kind of way or even more depend on your tastes. It can be as cute and caring in pretty dresses and so forth!
The Super High School Level Lancer (of Despair?)
What happens if her wish was indeed based on despair and end her father's life in a fun, tasteful, and sadistic matter? This Kyouko carries on the blood-thirsty and whacky self with maybe a slice of yandere traits for a certain bluenette. Kyouko is tidy, cute and clean, but the "executions" were not! Want to become a fried shrimp? No problem! Kyouko has you covered! Setting up a death trap as you sing for Doki Doki Idol Night? She has your covered!
At best this Dangan-Rompa inspired universe was loosely based on the IDEAS and not the "story" itself! Some character references may mentioned in her RPs, but will try to keep spoilers away for those who are really into it...
