Saja Ringo.

Saja means "lion" in Korean, Ringo means "apple" in Japanese. How ironic.

For one thing, Saja Ringo has apple-red hair.

For another, in middle school she was a street fighting punk and earned the nickname the Red Lion because her unique, self-taught fighting style is a lot like a lion attacking its prey.

When she moves to a new high school, Saja Ringo wants to leave that all behind, make friends (hopefully), find a boyfriend (although highly unlikely), and never, ever return to her old ways.

When she sees a little girl getting beaten up by a bunch of punks, she's forced to beat up the bullies in order to protect the little girl.

But 6 groups of people see her. And not just any groups.

SHINee group: kind but naturally skilled fighters that only fight to help others if necessary.

DBSK gang: rich kids of "Upper Seoul", hard-partying fighting maniacs that just love to crack some skulls.

Beast group: heartfelt and lonely outcasts who want to become pro fighters and make a name for themselves.

Big Bang gang: born tramps of "Lower Seoul", spray-painting, skateboarding hooligans who are always fighting with DBSK.

2PM gang: mysterious, dangerous people that dominate the underground, and are sworn enemies to DBSK and Big Bang.

Girls' Generation: a mixed group of skilled female fighters each torn between destroying a group/gang or loving one of their members.

With all these groups having their eye on Saja Ringo's unique and deadly fighting style she's trying so hard to leave behind, how can Ringo keep the lioness inside her?

Love, rivalry, drama, warfare, and bloody battles await her new and exciting junior year at SM high!
