I like it! It has a lot of potential. Since the first chapter is just setting the plot up, and the second one is just nudging the plot on a bit, the fic has a lot of different paths it can take. I can't wait to see what you do with it.

Just one little thing - Kira never did drugs. Kato was the user. Kira even once told Kato that he should stop because it was no good for him. And in the scene that Setsuna saw of a different, better version of life where Kira was still a bookworm and his sister wasn't his sister, Kira caught Kato and told him not to sell drugs on school property. Yeah...I have too much time on my hands. Anyways, for the sake of the fic, having Kira as a drug dealer and ex-drug user doesn't hurt anyone so...I'm gonna shut up now.

Looks good. I'll keep an eye on this story, so good luck.
