Ein was a hitman on hire. A killer, a shadow, a death with insomnia, if you may.He had witnessed countless pairs of eyes dim as the light of life faded, leaving nothing but vile hollowness. Needless to say, the sight of a soul popping out of the dead body was a first.And it wasn't just any soul. It was the dead heir of Byers Holdings, the same guy he killed with his own hands. Turns out the rich boy Adriel had a horribly irritating and loud soul, but worst of it all - impossible to get rid of.Who would have thought that killing on a blue moon night could lead to being haunted?

This is not your usual isekai novel. it has my unique world background, unique power system and i am trying it make it a unique experience for every reader. :)

Athan, a 16-year-old boy, lived until he was killed for a stupid reason. (stupid reason & more in the prologue:v)

But it seems that fate had stored different things for him as after death as he transmigrated in the magical world inside a dead body of a boy with the same name and same facial features as him.

He also found out that a mysterious black whirlpool seemed to be inside him.

Was someone responsible for his transmigration? if so then who? and why? or was it pure coincidence that he got a new chance at life?
