"My turn..." say Karyn cooling down from the scene.
She takes the stone Jon give her. She wasn't really into the idea, but now she have seen it, it gives her ideas.
"I wish that when I hold out my arm and say 'Karashi comes' a katana comes into my hand and I turn into a japanese girl with samurai anime-like capacities. I wish when I put the katana in his case and say 'Karashi back' I turn back to my normal body with the clothes I had before I changed."
Then the stone glow and Karyn give it back to Jon.
"Wanna try before we're too late for school ?" says Jon.
"Too late for school ? I don't think so..." answer Karyn as she holds out her arm and says "Karashi comes" and a red glow start from her and take the shape of a sword and then engulf her before it fade and left a living cosplay in front of Jon.
With her long gray hairs, her yellow beast like eyes, her white skin and her red eyeshadow, she is really scary.
She then say.
"First at school and start racing in a inhuman speed and makes huge jumps over cars and walls."
Jon quickly turn into his alter-ego and start running after her.
But every super-heros needs a supervilain, and it's always someone close to them... like maybe... Sarah ?
