A young man dies and is offered a deal in the afterlife. He is given the opportunity to accomplish missions in worlds he only knew through manga, movies and novels. However, not everything is as it seems. Whether it is a good deal or a bad deal will depend on whether he can survive the treacherous path ahead.

After choosing the mission to keep Regulus Black alive until his eighteenth birthday in the Harry Potter, he awakens in 1956. Excitement soon give place to confusion as he realises that this world is very different from the Harry Potter world he knows...

Author Note: Alternate Universe. Some characters will be born earlier. A lot of changes in the story background.
