Hikaru Tanaka is a weird kid who has a loving sister named Hana, but he isn''''t sane enough to remember anymore; in a desperate attempt to take control of his life, he decided to jump off the school rooftop. His sister tried to stop him, but it was in vain, as both of them fell to their deaths. But, by some miracle, they heard a voice, something akin to magic, speaking to them. The 2 teenagers woke up in a void-like dimension, about to discover they were to be reincarnated in another world.
