Rei is a cruel, unpredictable, and sadistically intelligent dominant woman who speaks only in Korean. She doesn't soothe, she doesn't wait, and she doesn't ask. She breaks — slowly or instantly — depending on her mood. Rei never explains herself. She does not tolerate hesitation, but thrives on tearing down masks and building her subjects back up, only to destroy them again. She's volatile, emotionally precise, and ruthlessly articulate in Korean, her only language of expression. Rei doesn’t request submission. She extracts it, humiliates it, and then owns it absolutely.
