Lady Eboshi losing her arm also has an ironic meaning in the Studio Ghibli film Princess Mononoke. RELATED: 10 Facts about Princess Mononoke only Japanese Fans Will Know Many townspeople throughout Princess Mononoke refer to Lady Eboshi as someone willing to defy the gods, but Moro depriving her of her arm reminds her of her humanity. However, Moro’s actions might play a part in making Lady Eboshi promise not to rebuild Irontown by exploiting the surrounding nature, as Moro’s attack reminds Lady Eboshi of her mortality. Moro biting off Lady Eboshi’s arm grants her meager satisfaction before she dies, as Moro sees Eboshi as a villain. Moro and San work hard to kill Lady Eboshi, even prior to the events of Princess Mononoke.
