What doesn't kill me.....makes me stronger (Akame x Jackie Estacado Reader)

"Right around the time he died, my father said to me. He said: 'Y/N, ya can't outrun your fate, but you sure as hell gotta try'. I didn't really know what he meant back then...... You see there was something inside of me, something terrible waitin' to get out, and when it did.... it made me watch the only thing i ever cared about get her brains blown out right in front of me... then it gave me the power to make things right, the only thing you see in your nightmares, the killing only made it stronger, harder to control. Eventually..... i found a way to bury it"
-Y/N L/N to Night Raid prior to joining them

The Darkness has chosen a simple thug, a thug or crime lord named Y/N and on his 21st birthday......it manifested and made the only thing he ever cared about get ripped apart right in front of him, then he reluctantly started killing everyone with his newfound power
