Byleth Eisner is the main character of Fire Emblem: Three Houses as well as the player avatar of the game. Byleth is a member of a band of mercenary led by their father Jeralt. After discovering a mysterious power hidden within, they are offered a post as a teacher at the Officer's Academy of the Garreg Mach Monastery. As such, they are the teacher of most of the playable characters in the game. They also appear in Super Smash Bros. Ultimate as DLC fighters.
Personality and Appearance
Byleth has a very subdued personality and has difficulty expressing emotion. As a newborn, they neither laughed nor cried. People they are especially close to, such as Jeralt, are able to tell how they are feeling despite their limited emotional visualizations. A handful of their students note that their outward expressions hardly vary. Some express surprise whenever they simply smile. According to Alois, this trait of theirs may in part come from their father, as Jeralt does not show his emotions easily either and can also be difficult to read. This should not be taken as them not having emotions at all however. Due to Jeralt concealing a lot of information about the world, they are showing curiosity about the influence of the Church of Seiros, the mystery of the Crests, and the dynamic of the three nations once they were immersed into the Officers Academy.
Their stoic demeanor slowly changes over the course of the Academy phase. Jeralt notices that they have become more expressive over the first few months, likely a result of the bonds they have formed with their students. Despite appearing indifferent, Byleth can be perceptive of their students and fellow faculty's problems and serve as a great source of emotional support for their issues. As the story unfolds, their emotions become more dynamic including feeling true sorrow, vengeance, and happiness.
Byleth has somewhat of a reputation from their earlier years in their father's mercenary corps for being a fearless and skilled warrior, gaining the moniker of 'Ashen Demon', due to the way they seemingly emotionlessly cut down their enemies in combat. This seems to be somewhat of a sensitive subject for them, as they seem uncomfortable when Hanneman mentions their moniker in their C support. It is notable that in the beginning of the game, Sothis refuses to let the player progress if they do not acknowledge their humanity to her, refuting the "Ghost" and "Demon" options, so it can be inferred that Byleth are uncomfortable with the Ashen Demon moniker because it dehumanizes them.
The three house leaders of the Officer's Academy attest to their martial prowess and have deep, profound respect for their abilities and guidance in battle and in the classroom. They alongside the other students continue to refer to them as teacher or professor even after the time-skip. The three house leaders also deeply regret that Byleth had not chosen their house if they are not teaching theirs, seeing the value in their strengths.
According to both genders of Byleth in Heroes, they do not actually know the distinction between a friend and an ally due to their unusual childhood. Nevertheless, they are well liked by the student body, even those not in in their initial house. Their wisdom ultimately shapes the outcome of the events of Three Houses providing council and guidance to the house leader they chose to teach, helping to shape them into better warriors and leaders. Several students can develop an interest in them and eventually switch over to their house if not already in them. This results in them also joining their 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 them in battle. However, some students and faculty members, especially in the Crimson Flower route, will instead express outrage at them, vowing to kill them by their own hands.
According to their profile in Cindered Shadows, Byleth has interests in helping and listening to people, likes swords, reliable allies, smiles, and being trusted, and has no apparent dislikes.
Byleth was born as the child of Jeralt and Sitri Eisner on the 20th of the Horsebow Moon in Imperial Year 1159. Sitri died after giving birth under mysterious circumstances unknown to most, leaving Jeralt devastated as he was told she died from childbirth complications. Jeralt called a doctor in secret to examine Byleth, only to learn that Byleth had a pulse-- but no heartbeat.
In truth, Sitri was the 12th vessel created by Rhea to try and revive the Goddess Sothis. Sitri, along with the predecessor vessels, were unable to host the power of the Goddess, which made Sitri frail and unable to leave the monastery. When she met and fell in love with Jeralt, Jeralt had the Crest of Seiros, creating a perfect recipe for reviving the Goddess in their child. Byleth and Sitri were about to die, where Sitri demanded Rhea to transfer her heart into Byleth's, where Rhea agreed. While the transplant was successful, it killed Sitri and made Byleth lack heartbeat.
On the 7th of the Wyvern Moon in 1159, Jeralt left the Knights of Seiros to go to Remire Village to raise Byleth as a mercenary, using a fire that broke out to fake the baby's death.
Byleth was then raised as a mercenary, gaining the nickname Ashen Demon from others for striking down their enemies in combat without emotion or hesitation.
