I don't have too many, but the ones I hold dearly to are my Touhou OCs. If they existed, they wouldn't be important to a game probably.
They're all of Suwako's descendants. I wanted to make a story focusing on the most important descendant of each Japanese era.
The two I have most thought out are Kikumo from the Heian period and Sachie from the Shōwa era.
Here's a bit of their stories
Kikumo
A long time ago, there lived an infertile priestess. She was getting old, and it seemed like a child was never coming her way no matter how many times she tried.
So, every day and every night, she'd pray and pray until one morning she sat by the lake and a small figure emerged. That figure was Suwako and told the priestess that she would give her a "seed of life" and if the priestess had swallowed the seed, she would give birth to the most blessed child in the world.
As well, Suwako gifted the priestess 3 iron rings for her future child to use. She was confused at first, but as soon as Kikumo grew, she knew what it was for.
Kikumo was always different. She possessed immense strength and became skilled in fighting at a very young age. She was energetic and tough, unlike the graceful image of a traditional shrine maiden.
The people admired how she protected her shrine and how powerful and skilled she was.
One day, the emperor had heard of the power Kikumo had.
There was a giant frog that kept snatching children in the middle of the night. Nobody could do anything to stop it.
He knew that Kikumo was the only one that could tame the giant frog.
And she did (his name IDK right now).
I still need to figure out what she does with the rest of her life but I think the taming the frog monster is a good start.
Sachie
3 generations after the descendants of Moriya left their shrine, another gifted woman was born into their family. And her child would be especially gifted as well.
She was born on a summer day in 1965. Her parents were poor and her father was abusive, beating her over the smallest mistakes.
Sachie didn't know how to cope with the stress every day, so she became ruthless and violent to everyone she know. She fought everyone who breathed the same air as her. One day, a shy, meek girl had enough with the fighting and spoke up. Sachie had beaten the girl up so well, she was hospitalized and Sachie got expelled.
Her parents didn't care about her education, so she had nowhere to go.
Until she ran into the Diamond Rings, the most infamous girl gang in the entirety of the Nagano prefecture. The leader Hisako saw Sachie, so full of worry and despair, and took her in. There, Sachie trained hard as she could so she could be unbeatable.
One day, Sachie noticed something about the 3 bracelets that sat on her wrist. Her mother had told her they were a family heirloom and to never loose them or else she'd get bad luck. She never knew why, but now she did, as she realized if she focused enough, she could control them and use them as a weapon.
And that was the day the Diamond Rings became even more legendary than they ever thought they would be.
While walking in the streets one day, Sachie had unfortunately ran into the men's gang. Sachie had become pretty well known at this point, so instead of challenging her, they honored her. It was the first time they had met, but Sachie had instantly fallen in love with this one man, Juuro.
Sachie had gotten unexpectedly pregnant, leading to a shotgun wedding. She loved her child so much, but with the unknowingly great power she held, she was going insane from it. 4 months after her giving birth, she became almost completely unable to take care of the baby.
So, in a dream, Suwako reached out to Sachie and told her to leave the baby in Suwako's hands. At the shrine.
Sachie had no idea where the shrine was, but as soon as she woke up, she suddenly knew where to go. So, she told Juuro to say goodbye to the baby, hopped on her chunky bike, and dropped the baby off at the shrine.
You probably know who that baby is by now.
