Felt (フェルト) is a former thief and a candidate to become the 42nd King of Lugnica. She is a supporting character first introduced in Arc 1, where she plays a major role. She also played a supporting role in Arc 5.
She was hired to steal Emilia's insignia, but later ended up fighting alongside her, Natsuki Subaru, and Reinhard van Astrea against Elsa Granhiert. Afterward, she is forced to participate in the Royal Selection after being chosen by the insignia. Having grown up in the slums, she takes the opportunity to get revenge on the Kingdom by making her primary policy to disband all government.
Furthermore, it is heavily implied that Felt is, in fact, a member of the Royal Family and the missing daughter of His Majesty's younger brother Ford Lugnica, who died roughly a year before the events of the main story. 14 years ago, a group of thieves stormed into the Royal Palace and kidnapped the Ford's child. In both appearance and age, Felt matches all descriptions of the missing Royal Family member. Some important figures such as Reinhard van Astrea and Miklotov McMahon have already pointed out the very high likelihood of this being the case, as well.
Felt is a short girl with fair skin and medium-length golden hair with a black bow. She has a yaeba that becomes prominent when she laughs. She has red eyes and wears a black top, red scarf, and black pants that are incomplete on the left side, where she also wears a red ribbon. She also wears a vest, gloves, and brown shoes, and has a belt with a sheath where her knife is. When Reinhard took her, he forced her to wear a yellow dress, white sleeves on his hands, boots, and an orange bun in the center of her hair to look presentable as a candidate for the throne in the Royal Election.
After the Royal Election Ceremony, Reinhard makes a new outfit for Felt. Just like her former outfit, it's very light. She wears a black top, a blue cape with her former cape being red, a leather brown jacket, boots of the same material, black leggings, a black belt, and a brown leather pants, which she wears on top of the leggings. She keeps a few pouches on her belt.
Her appearance is considered to be a sign of having royal blood. However, as all members of the royal family are currently deceased, there is currently no way to confirm if she actually is part of the royal family.
Felt is short tempered, hot headed, and rather unladylike. Reinhard has commented about this trait several times with Felt often not caring. She is also very childish about a lot of things, although this childish nature goes away when faced with a dangerous situation. Felt is a stickler when it comes to money due to living in the slums which also blessed her with a mentality of never allowing herself to lose in any kind of way. She cares about Old Man Rom and treats him like her real grandfather. She greatly trusts Rom's word, especially when it comes to appraisals in price. Felt has stated multiple times that she resents everything about the kingdom and plans to tear it all down, which is likely due to the way Felt grew up.
After spending a year living a completely different life from what she was used to, Felt started viewing the world in a different light, not being scared of changes anymore as she realized that change is a natural course of action; one she is unable to avoid. As a result, Felt developed a strong preference for the theory of the "Survival of the Fittest", where the one who could adapt to their situation and discern the best manner of survival would survive and strive over those who could not. Consequentially to this mentality, Felt believes she's what she is today due to the belief that she adapted, opting her to accept every decision she made thus far as something natural.
Felt was born roughly 15 years before the start of the main story, under circumstances that remain unknown until this day, though it's been heavily implied by multiple high ranking and knowledgeable individuals such as Miklotov McMahon and Reinhard van Astrea that she was, in fact, born as the last daughter of Ford Lugnica, the younger brother of the 41st and last King of the Dragon Kingdom of Lugnica, Randohal Lugnica. At an unknown age, early in her life, Felt was picked up by Rom, gave her her current name, and acted as her adoptive grandfather. For over a decade, Felt spent her days in the slums of the Capital, stealing from people in order to earn enough money to move out of the slums and start her own life. Starting off with simple pickpocketing, she broadened out and started accepting requests from other people. Soon, she became a master thief, earning a considerable amount of money through dirty business.
On the day of Natsuki Subaru's arrival to the new world, Felt accepted a very profiting job from a shady woman with a snake-like gaze, thinking this would be her last job, as 10 gold coins would be more than enough for her to start a new life somewhere outside of the Capital's slums. It didn't take her long to locate her target–a woman with white clothes with golden birds woven on it, and long, dazzling silver hair. Just as she was about to approach the woman and steal the object of interest she was tasked to take, another person grabbed the opportunity and snatched away the woman's purse. Just as he was about to scurry off into the the back alley, a tall old man in a black suit pressed his sword against the man's throat, demanding the thief to return what he stole. Noticing Felt, who was staring at the whole ordeal, he causally walked towards her, noting he knew she had the same intentions as the man he had just caught. Despite that, he kindly asked Felt to return the stolen purse to its owner. When Felt started objecting and stating she'll just scurry off with the purse, the man calmly rebuked her and for a moment, his stare became as sharp and cold as a blade, prompting Felt to agree to his request in fear. Right after, another person called out to the old man, catching his attention. Felt used the chance to escape to a back alley nearby. In the alleyway, she tried to confirm the object of interest was in the stolen purse, however, all she could find was change, barely enough for a short shopping spree. Annoyed, Felt returned to the main street and quickly located the woman who was, at the time, in the middle of a commotion, trying to get attention so she could pay for a demi-human child's meal. Felt used the opportunity to throw the woman's purse back to her, making sure she found it right after. Felt then continued to tail the woman who was aimlessly wandering around the Capital. After some time, Felt was finally blessed with a situation that would allow her to snatch away the object of interest. She used her Divine Protection to scale a large building, jumped off behind the woman and snatched away what she was keeping safe in her waist pocket. What Felt found was a black dragon-shaped insignia with a red stone shining inside her palm.
Divine Protection (加護 Kago): Felt has a currently unnamed Divine Protection which Elsa mentions is related to wind. Felt mentions that she's used to using this ability rather than relying on tools and weapons. The Divine Protection allows Felt to dash ahead as fast as the blink of an eye, exactly like the wind, releasing a gust of wind at the destination of Felt. It is shown that her Divine Protection can be used differently as well. During Arc 5, Felt has used her Divine Protection to climb up walls and buildings.
Melee fighter: From a young age, Felt has physically trained herself to become fully agile and strong at the time of fighting. She is so quick that she could steal the insignia from Emilia without her realizing it.
Earth Dragon: Felt was granted a Earth Dragon named Romy. She's a bright red Diana Species earth dragon. As an Earth Dragon, Romy has the Divine Protection of Wind Evasion (風避けの加護 Kazeyoke no Kago), which enables Romy to be unaffected by the wind and not encounter any wind resistance while running. After activation, there is a cool down period before she can use it again.
- Felt is the name Rom gave her and isn't her real name. She doesn't know her real age either and claims to be around 15 at the start of the series. In Arc 5, Lye tried to eat Felt's name but couldn't "eat" it because Felt is an alias given to her.
- According to the author, Felt considers her birthday to be August 8, the day Rom found her.
- According to the author, Felt is scheduled to be active around Arc 9.
- In Arc 1, during Elsa's attack, Felt ran for help and encountered Reinhard who she asked for assistance. The author later revealed that the place the two encountered each other for the first time was the same place where Wilhelm Trias and Theresia van Astrea first met, 40 years before the start of the main story.
- Shinichirou Otsuka, considered her to be easy to draw in comparison to other characters. In fact, they were able to complete Felt's design in under an hour.
- Felt only is interested in older men.
