SWEETHEART is a character and enemy in OMORI. She serves as a major antagonist who continuously causes trouble for OMORI and friends throughout the majority of the HEADSPACE segments in the game. After having a breakup with a former lover (while also imprisoning him) named Rococo, Sweetheart has been fixated on a quest for true love, which she found in Captain Spaceboy...only to actually divorce him the very next day they got married. It goes without saying that she is entitled and bratty.
