A Multiverse Where Nothing Goes My Way

Our protagonist gets reincarnated by a ROB (??) who has placed an unbreakable curse on the protagonist in exchange for his path to power as nothing in this omniverse is "free" and there is always a price to pay for quick and easy power. NOTE: THIS IS AN EXPERIMENTAL FANFIC I WILL UPDATE WHENEVER I WANT SO IT MIGHT NOT BE CONSISTENT AND THE STORY MIGHT NOT BE CONSISTENT AS I AM A FIRST TIME AUTHOR. THIS IS MY FIRST SERIOUS NONTROLL STORY. Constructive criticism is welcomed and wanted.
