Yoon Karma is a young North-Korean girl who escaped to South-Korea.

When she was in North-Korea, she was subjected to numerous torturous scientific tests by her own father that caused her to develop a psychopathic attitude, along with superhuman abilities.

When she escapes to South-Korea, she's adopted by a powerful chairman so he can use her skills get revenge on the girls who bullied his daughter: Hyena, to suicide.

Yoon enrolled into the same high-school as the bullies to avenge Hyena, & to make anyone who bullies her & others her "plaything" so she can have fun.

Despite her extraordinary strength, Yoon Karma is a beautiful young woman who has an average height & a slim build. She has short dark-blue hair, bright blue eyes, & a mole under her left eye. The right side of her fringe hovers above her right eye, while the left side of the fringe & left side-bang are tucked behind her left ear.

When at school, her uniform comprises of a white, short-sleeved dress-shirt with a dark-blue collar, dark-blue skirt & white trainers.

Outside school, her casual attire is a black choker with a black leather jacket, worn open over a white T-shirt with the Gucci logo on it & exposes her midriff. She also wears black short denim shorts & black flat-boots.

Upon introducing herself to her classmates, Yoon Karma is someone who comes off as cute & naive, & the type to stand up for bullies. But this is simply a ruse that's quickly uncovered.

In actuality, she's a girl who finds pleasure in fighting & hurting people that either piss her off or wrong her in some way. She's also extremely intelligent as she decides to not follow her "step-father's" original scheme, but rather single handedly come up with her own elaborate plans to enact revenge on Hyena's bullies that would cause them even further pain & humiliation.

She also only goes after people who seek to harm her or were the ones who were responsible for Hyena's death, implying she does have morals.
