Be warned guys, i do this just for fun and when i have time. English is my third language so expect some grammar, spelling and sentence construction error. synopsis a man died and brought to a realm he never knew, he learned that he's not the only one there and start approaching them. he accidentally devour a soul and learned every knowledge the devoured soul learned. he is in ecstacy and absorbed/devoured every soul he sees. but who would have thought that he suddenly picked the interest of an unknown being. let us watch/read his journey to different worlds while fulfilling the desires of others.
