Epona Rhiannon

Epona Rhiannon is a character who holds great importance in the series. According to Goddess, she is the hero who will destroy the world in the future. She is considered a man in the family register, but genetically, she is actually a woman.

Appearance
Epona has short yellow blond hair and red eyes. Like Lugh said, her gender's identification is difficult to be figured at first that she is easily mistaken to be a male.

Personality
The Hero is said to be an almighty being of all time who holds great wisdom and immense power with no limit. That being said, Epona is actually a shy girl who can't communicate with others and became awkward in advancing the conversation. Being raised in poor peasant family, she have a high inferiority complex, not wanting to involve in unnecessary troubles. She is shown to have a weak heart when it comes to facing the deaths of her beloved comrades. She is a pacifist at heart and doesn’t like engaging in violence. She also has a fear of letting loose as she can’t control her powers and emotions, which traumatised her as she had caused harm to many of her friends.

Although she is labelled as a 'supremacy being' by the people, she doesn't act narcissistic or arrogant due to her title and privileges. Indubitably, she is kind person who doesn't want to hurt people with her power. She is also have a keen curiosity in learning magic, making friends and doing all other things that a normal student would normally do. Upon meeting Lugh, she admits that he was more deserving of the title Hero which he rejects as he was an assassin through and through.

Background
Epona was not actually born with the skills granted to her as the Hero. She grew up as farmer on the outskirts of the Empire. Needing all the hands they could get, her family falsely claimed she was a man on her birth register so she could help out in the fields. As a result, Epona spent every day of her life working in the fields until she awoke her skills and was subsequently taken into custody by the Kingdom. Whilst under royal protection, the knights would attempt to teach her how to fight, only for her to easily beat them all, leaving her annoyed at how easily all her opponents would "break". This made her desire for a sparring partner that could keep up with her, a wish that was granted after she entered the Royal Knights Academy and met Lugh.

Abilities
According to the Goddess, Epona is powerful enough to destroy the entire world singlehandedly. As noted by Lugh, despite being a total amateur at fighting, her overwhelming power more than makes up for it. In fact, he only won their practice match due to the rules, admitting she would have easily beaten him in a real fight. What is perhaps most terrifying about Epona, however, is that she is still in her "growing phase", meaning that, despite already being arguably the strongest character in the series, she is still getting stronger.

Skills
Due to being the Hero, whereas other people only have five skills at most, Epona boasts a grand total of thirty. In addition, five of these skills are S-Rank, whereas the remaining are all A-Rank. For comparison, normally the chance of having an S-Rank skill is one in a hundred-million, and that alone is enough make the owner one of the strongest people in the world. Similarly, the chance of having an A-Rank skill is one in one-million.

Strength
In terms of raw strength, Epona is unmatched, being able to defeat any opponent with just a single punch using her non-dominant left arm. Even Lugh admitted that she would instantly beat him if even a single one of her hits connected. However, her overwhelming power also means that Epona has difficulty using weapons, as they would break if she swung them with too much force.

Speed
Epona boasts incredible speed and agility, with Lugh barely able to keep up with her even whilst pushing his body to the limit using a combination of【Rapid Recovery】, 【Martials Arts】, and his Mystic Eyes.

Endurance
Epona's body has a level of endurance that borders on invulnerability, with Lugh being unable to put even a single scratch on her during their practice match. In addition, when Lugh threw a knife at her, it broke upon making contact with her skin. Similarly, when he managed to land a hit on her that won him the match, he was the one being blown back instead of her.

Magic Attribute
Despite having no knowledge on magic whatsoever, needing to read her spells off a piece of parchment, she is able to melt metal using a single low-level spell like fireball.

Lugh Tuatha Dé
Lugh is the first friend Epona made in the academy. He was tasked by the Headmaster, the mission of get along with the so-called "Hero", which Lugh easily earns her trust and built a friendship with her. Lugh had been given a mission of killing the hero by Goddess, but being an assassin he decides to determine what kind of person she is, before deciding whether to kill or save her. After meeting and talking with Epona, he came to the conclusion that she is an inexperienced child and has a weak willed heart, and so he decides to protect her instead of kill her since she doesn’t possess any ulterior motives. He then taught her academically and acted as her sparring partner which developed their relationship further. He empathises with the pressure put on her by society and that after she accomplished her mission, she would most likely be exterminated by the Capital much like himself if they ever find out about him. Thus, he sets out to surreptitiously find a way to rid her of her powers after they destroyed all the demons so that she can live the normal life she deserves.

During their first demon fight, Epona indirectly injured him during the battle. Since then, she actively avoids him in school. During the raid of demons in the city, Epona was injured in a battle with a demon. She couldn’t use her full power as Lugh was present and she shouted that she can’t trust him as he failed to uphold his promise to stop her during their last battle. Lugh then asked for her forgiveness and for another chance to show his truth power. After being saved by Lugh and witnessing his true power, Epona made him promise that if she ever went berserk, he must kill her. Although he promises her on the outside which she smiled to, Lugh vows to himself that he'll save her instead, if it ever comes down to it.

It is worth noting that she has developed romantic feelings for him ever since their first battle. This is mainly due to the fact that he was the first person to ever treat her without any reserves, and actually defeated her in combat. Furthermore, she forced the school to make him her personal sparring partner, which improves the skills of both people immensely. When the nobles only credited her for defeating the demon and completely disregarded and even lambasted Lugh, Epona was angered and stood up for him. He then sincerely apologised to Lugh as she told the truth to the nobles after she promised that she won’t reveal Lugh's powers and feats to them. Lugh forgave her and as an act of reconciliation, she shared her powers with him using the 'My Loyal Knights' skill. This is significant as only 3 people are allowed to have this power. After sharing her power, she made the biggest vow to him that if he ever meets a predicament, she would drop everything and run towards him, even if it meant disobeying the King.
