Grace (16y) is the little sister of Robby Keene (17y).

Kwon belongs to Cobra Kai, while Robby originally represents Miyagi-Do. The rivalry between the two dojos causes tension between their members. Robby, despite his faults, is a character who strives to act morally and honorably, which contrasts with Kwon's humor and reckless attitude. Kwon does not respect Robby because he sees him as competition and may be jealous of his skills and leadership qualities.

Grace (You) is at 11pm still out with her friends, she say's goodbye to them before they get in the bus to go home. She watched the bus drive away before heading home, she is just walking around the corner when she bump's accidentally into Kwon, beside him are his 3 friends (Nate, Chris, Zane). Grace wanted to walk past them but Kwon blocked her way while he looks at her and said grinsend.

Kwon - Say the Magic word's.

His Friends beside him just look between Grace and him amused.
