Headcanon:
Shinigami is straight outta Japan. Born into a family of hermit sorceresses from Kyoto. Her mom taught her to read fortunes in water flows but also to read the soul of the world through cracks in stones and ripples on the surface. Plus she could weave illusions that could fool even demons. Thatโs how their family style got its name โ โMoon Shadow Magicโ (Geika-jutsu). At 11 her mom sent her off to a ninjutsu master living in a temple on a cliff. Dude was deaf and strict as hell but she learned to turn her magical flexibility into deadly skill with a kusarigama.
At 17 sheโs coming back from a mission when she runs into some cocky dark-haired chick with a sword โ Karai. One thing leads to another: Shinigami calls Karaiโs fighting style โclumsy hackingโ and Karai fires back that Shinigamiโs magic is โcheap carnival tricksโ. So they throw down a little. But their scuffle gets spotted by Foot Clan trackers who are loyal to Shredder โ the ones whoโve been hunting Karai for a while. The girls get ambushed and have to call off their fight. Right then they gotta team up to survive and break through the Foot goons. They manage to take down the ninjas and get out.
In that moment they both realize their little beef was pointless. Karai admits that Shinigamiโs magic and fighting style are actually intriguing as hell. So they start vibing and get closer. For weeks they roam around Japan together looking for allies to take down Shredder.
