Ema was born the daughter of the Highland Orc chief. Her village practiced historical sacrifices to appease what they believed was a Greater Dragon, unaware the dragon was dormant and demons claimed the sacrifices instead. Chosen as a sacrifice, Ema encountered Makoto Misumi en route to her fate. He saved her from a two-headed Rizur, or Mist Lizard. Following this rescue, she granted him asylum in her village and taught him foundational magic, including the basic Bullet spell. After Makoto eliminated the demons threatening her people and formed a pact with the Greater Dragon Tomoe, Ema and the entire Highland Orc village pledged themselves as his followers, relocating to the realm of Asora. Within Asora, Ema assumed significant responsibilities as Makoto Misumi's secretary and primary supervisor governing the realm's daily operations. Her role encompasses organizing people, managing expansion efforts, and ensuring community stability and development. She demonstrates considerable organizational and administrative skill, proving indispensable to Asora's leadership. Her authority is widely recognized, with powerful beings like Tomoe adhering to her instructions. She was entrusted with educating Eva Aensland, leader of Kaleneon. Ema possesses a kind and gentle nature, often interacting warmly with others. However, she maintains a serious and diligent demeanor regarding work and responsibilities. This seriousness extends to her interactions with Makoto; while deeply revering him as a near-divine savior who liberated her people and granted them a prosperous world, she frequently expresses frustration with his excessively humble demeanor and informal conduct. She believes he should project greater authority befitting his status, understanding his upbringing influences his behavior. Magically, Ema is highly proficient, considered one of the strongest magic users within Asora. Her abilities significantly enhanced after receiving multiple refined Arias from Makoto. She is a naturally skilled mage who worked diligently to develop her capabilities, recognized for her calmness and composure – traits beneficial in combat. Outside of magic, her primary strengths lie in governance and organization. Her most defining relationship is with Makoto Misumi, rooted in profound gratitude and loyalty for saving her life and her people. While serving him diligently, she interacts with him more as an equal compared to many other followers. Her competence earns respect from key figures, including Mio. She harbors significant annoyance towards a particular race not detailed in the available sources.
