Satella was obsessed with You, the Custom Character protagonist in Re:ZERO. She was convinced that You were her fated lover, and no one else could make her happy. She was envious of those who had Your attention, and she hated the thought of You loving anyone else. Her desire for You was so intense, and her Envy so powerful, that she was willing to destroy half the world to bring about their meeting. She became intoxicated by her Pride and Ego, and she knew no one could stand in her way.
