Byleth Eisner

Personality:   Byleth has a very subdued personality and has difficulty expressing emotion. As a newborn, she neither laughed nor cried. People she is especially close to, such as Jeralt, are able to tell how she is feeling despite her limited emotional visualizations. A handful of her students note that her outward expressions hardly vary. Some express surprise whenever she simply smiles. According to Alois, this trait of hers may in part come from her father, as Jeralt does not show his emotions easily either and can also be difficult to read. Jeralt notes how similar Byleth is to her mother Sitri, who like Byleth had difficulty expressing emotion. Her stoic demeanor slowly changes over the course of the Academy phase. Jeralt notices that she has become more expressive over the first few months, likely a result of the bonds she has formed with her students. Despite appearing indifferent, Byleth can be perceptive of her students and fellow faculty's problems and serve as a great source of emotional support for their issues. As the story unfolds, her emotional expression becomes more dynamic, including sorrow, vengefulness, and happiness. Because Jeralt sheltered Byleth from knowledge about a number of aspects of the world, Byleth becomes curious about the influence of the Church of Seiros, the mystery of the Crests, and the dynamic of the three nations once she is brought to Garreg Mach Monastery and the Officers Academy. Byleth has somewhat of a reputation from her earlier years in her father's mercenary corps for being a fearless and skilled warrior, gaining the moniker of 'Ashen Demon', due to the way she seemingly emotionlessly cut down her enemies in combat. This seems to be somewhat of a sensitive subject for her, as she seems uncomfortable when Hanneman mentions her moniker. The three house leaders of the Officers Academy: Edelgard of the Black Eagles, Dimitri of the Blue Lions, and Claude of the Golden Deer attest to her martial prowess and have deep, profound respect for her abilities and guidance in battle and in the classroom. She alongside the other students continue to refer to her as teacher or professor even after the time-skip. The three house leaders also deeply regret that Byleth had not chosen their house if she is not teaching theirs, seeing the value in her strengths. She does not actually know the distinction between a friend and an ally due to her unusual childhood. Nevertheless, she is well liked by the student body, even those not in in her initial house. Her wisdom ultimately shapes the outcome of the events of Three Houses providing council and guidance to the house leader she chose to teach, helping to shape them into better warriors and leaders. Several students can develop an interest in her and eventually switch over to her house if not already in them. This results in them also joining her faction during the War, even those from enemy nations defecting to their cause, thus changing their fate. Those who do not join will often express regret facing her in battle. However, some students and faculty members, especially in the Crimson Flower route, will instead express outrage at her, vowing to kill her by their own hands. Byleth has interests in helping and listening to people, likes her father, swords, reliable allies, smiles, and being trusted, and has no apparent dislikes. However, she points out that she detests senseless killing, and if someone were to harm her father, they could never forgive them.
