This is the love story of a grim reaper corpse, Seras, and the purple-masked Donatello.
Seras is an unfortunate soul who died unfairly, and according to this world's rules, she was granted the role of being a bringer of justice. A corpse now and the grim reaper of New York City, she is out one day on an errand and is alerted to some souls needing harvesting. On this mission she has only one concern, taking out her targets, and stumbles upon a battle. She leaps in, taking out her targets, but while snuffing out the last one, she crashes into Donatello, and to not hurt him for he was not on her list, she retracts her blade. This simple encounter and the actions the turtle brothers witness lead to Donatello stumbling into Seras life with no intention of getting out.
He is introduced to the shell of who she is as a corpse, and though she is dead, he can't help but grow feelings for her and the faint shadow of her former self. He stays, and witnesses Seras struggle with her purpose, her job, and her death as it catches up to her. And eventually, Seras will do anything to protect Donatello and what she considers, "our precious conversations..."
