[Until We Meet Again] • Sanders Sides AU

! TW: Death, Murder, Violence, and Grieving.
The sides can die. Well, more like they can be murdered. They couldn't die of old age, sickness, or starvation, but pretty much any other method could kill them. When a side dies, a new side will form to replace them. These new sides have different personalities, names, and outfits, only keeping the title of their predecessor.
Needless to say, with "object impermanence" no longer in effect, Remus had killed a few sides on accident.
It all started when him and Roman were kids, and had gotten into a fight. Remus went too far, and lost his brother. No he swears to kill any and every replacement that forms in his place, hoping that eventually his brother will come back.
