For Had Hatter Belia's "OMG! ANOTHER CONTEST!! 0[]0" It has to do with a story I'm writing called A Kyuubi's Happiness But she, Hiruka, and Sou don't show up until later chapters. As for her info and background story:

Full Name: Sou Jashin

Age: 14

Hair: pure white

Eyes: bright green

type: Generic human

My story for Kiri, Hiruka, and Sou:

Created through genetic mutation, Kiri, Hiruka, Sou, Kouji, and Riku are the next generation of Akatsuki. They all struggle with their share of misfortunes, also being joined with the biiju's powers.

Sou is the quiet person of the group and the most level head. When she snaps, it's like a volcano erupted, though. the curse words fly everywhere. She is the strategist, and normally the potion maker. She watches Riku in his sleep, and normally turns to Kiri for help.
