Arthur Ironsmith, 28, a normal life, normal dreams. Until he dies… from a heart attack. So unlucky.

But when he thinks all is over, two beauties arrive to carry his soul but… there is a little problem. Things go bad and he starts transmigrating by himself… the only hope is the kindness of one of the angels, who gives him a mysterious "Multiverse Library" before he disappears.

What awaits him at the end of the journey? What is this Black Soul that caused the problem? Why it's so bad that he wasn't expected to be there? Not all mysteries reside on the other worlds…
