So this is basically what is happening here, though it spoils some of the story so... Spoiler mode- activate! Now that I've done that, time to explain, Angelica is one of a group called the Guardians of Fate, each decade, a person given the duty of choosing the next ones to be tested will, well, choose who will be given the opportunity to become a Guardian, and will also choose the Guardian who will greet them. One of the doors is to become one of the Guardians, and then there are three others, so far I will only say the Reaper as that's the only one revealed. But once three Reapers, and five guardians, plus the others have all been chosen, each Guardian chooses a Reaper to end their life, and the Reapers are also to end the lives of every other, including the past Reapers, and the cycle repeats, Angelica has chosen Kade to be the Reaper who takes her life, despite him being the first chosen Reaper. Kinda dark I know.
