So where do we go after we die? There are a lot of theories on that matter Most people all over the world assume that the dead move on to the after life. The good people end up in heaven while the bad have to suffer in hell. Others assumed that you just wake up in paradise or something. She even remembered someone saying that maybe you get to watch over the lives of those you love. And others like the Hindus and Buddhists believe in reincarnation. They believed that someone who died with good karma they would be reborn into a good life. Those who did not have good karma end up with a bad life. Like any normal anime fan that had read a ton of reincarnation fan fiction of course the thought of being reincarnated into a cool anime world crossed her mind... ________________ You guys know how this thing goes.
