This idea came to me when I was l lying down in bed. This might be OOC. I'm not exactly sure though...

It was just another normal day with L and Light when an annoying blond mode-Misa-suddenly burst into the room.

"LLLLIIIIGGGHHHTTT!"

Just as Light was about to tell her that he and Ryuzaki were busy, she crashed into his chair, making him fly forward, and...
smash lips with Ryuzaki.

"EEEEEWWWWWWWWWWWW!"

While Light was reassuring himself that he wasnt gay, Ryuzaki was touching his lips saying,"That was my first ever kiss... ever..."

Light replied," That was my first kiss with a guy..."

"Misa-Misa was Lighty's first kiss, right?"

"Sure, Misa."

"YAY! Light, dont forget you have to get rid of the Ryuzaki germs! Hurry, hurry!"

Light just sighed and vibrated his lips together, sending his saliva flying at Ryuzaki.

"Keep your spit to yourself, Light-kun."

Ryuzaki turned away from light,and was now facing Misa. As he wiped his face, he muttered," Horse..."

Suddenly, he was being tackled by Misa, who was hitting him and screaming," WHAT DID YOU CALL ME?" over and over again.
L tried to speak,but no words would come out.

Meanwhile, Light was thinking,'Good job Misa. Just as we planned. You overreacting to what Ryuzaki said and then tackling him and hitting him repeatedly will eventually kill him!"

As Light was being insane, and laughing like the evil person he was, Ryuzaki slowly lost consciousness while thinking,' I am now more certain, if that's possible, that Misa Amane is the second Kira, and Light Yagami is the horse - I mean FIRST- Kira.
