Evelyn Decaro was a first-class assassin who had been working for the same organization, Rogue Assassins United or R.A.U, for most of her life. Though when that same organization she's devoted her life to exiles her, she lets nothing get in her way as she plans to leave the people begging and pleading for forgiveness just to kill them off anyway. However, when a familiar blue-eyed and brown-haired boy shows up unannounced into Evelyn's life, throwing her off from her ultimate and maybe last mission, she uses him as leverage--promising him something he's wanted done at one point himself. To get rid of the R.A.U once and for all.
