Emi Yusa(遊佐 恵美 Yusa Emi?) / Emilia Justina (エミリア・ユスティーナ Emiria Yusutīna?) is the main female protagonist and the Hero who defeated the Demon King Satan. After forcing the Demon King to retreat from Ente Isla, she followed him to modern day Japan to ensure that he is destroyed. However, just like the Demon Lord, she lost most of her powers upon her arrival and is forced to assume a Japanese name and find employment as a call center agent. She is a half human/half angel.
Emilia was raised by her father on a farm in Ente Isla during Satan's conquest where she lived a peaceful life with her father, Nord Justina. Despite fearing the day they would be accosted by the encroaching demon army, he assured her that their village would be protected from the Church, putting her mind at ease. Her life changed drastically one afternoon when representatives Church arrived at her home to train Emilia as the Hero who could free the world of the Demon Lord Satan. While the young child remained uncertain of her fate, the clergy went on to explain her responsibilities as the daughter of an angel. Her father confirmed this by telling Emilia of her mother's true nature, allowing her to be passed into the care of the Church. Although reluctant at first, her motivation was fueled when she received news of her father's apparent death when the Demon King's army laid waste to their fields.
During her crusade across Ente Isla, Emilia defeated Lucifer in the West, believing she had killed him while being unaware of his survival. She also forced Alsiel's retreat in the East while slaying the remaining two Demon Generals, allowing the hero to proceed to the central continent. With the help of Emeralda, Albert, and the High Priest Olba, she proceeded to storm the Demon King's stronghold, defeating him while slicing off one of his horns in the process. Satan then opened a portal and escaped, but not before announcing his intention to return and reconquer Ente Isla. Emilia pursued him through the portal, and then found that her companion, Olba Meyer, had failed to reach her in time.
Upon reaching the other side of the Gate, Emilia found herself alone on Earth and bereft of the majority of her powers. She forged an identity under the alias "Emi Yusa" while registering herself as an adult in her twenties. Desiring to find and finish the Demon King, Emi continued her search and moved into a small apartment somewhere in Tokyo, getting a job at a call center to sustain her living expenses. During this time she established a friendly relationship with her co-worker Rika Suzuki.
Emi's first encountered King Satan in Japan while standing at a crosswalk in the rain, but failed to recognize him at first. Seeing that she had neglected to bring an umbrella, Sadao Maou kindly lent her his own, noting that he wasn't far from the MgRonald's where he works. She identified him shortly thereafter and set out to confront the Demon Lord, pulling a knife on him during their second encounter later that night. Rather than express fear of the hero's wrath, Maou calmly noted the absence of her Sacred Sword, discerning that she must have ended up in a similar state as him, as he had purchased the very same knife from a nearby 100-yen shop. The racket attracted an officer's attention, who brought them to the police station for questioning, mistakenly taking the would-be knife fight for a lovers' quarrel. Emi became indignant at the insinuation that she was dating the Devil King, but upon leaving police custody, chose to suspend his execution for the night. Instead she resolved to keep an eye on Maou's day-to-day activities.
After a few days spent observing Maou and Ashiya, she found that the demons had been leading the lives of ordinary Japanese citizens, and thus offered to spare Maou's life as long as he remained on Earth. He ultimately refused, declaring that he still had plans as the Demon Lord to conquer both Ente Isla and the Earth. During their heated confrontation, the duo was greeted by a hail of magic bullets from an unknown assailant, forcing them both to flee to a more populated area to avoid the danger. As they ran for it, Emi dropped her wallet and was left without travel money. Although extremely unwilling, she requested to stay overnight at Castle Overlord, having lost her means to return home.
The next day, Emi received a mysterious call at her workplace. The person on the other end threatened to eradicate her, the Hero, as well as the Demon Lord. Later, she stumbled upon Ashiya spying on Maou and Chiho on their date, angrily confronting the Demon General concerning their intentions for the teenage girl. While watching the couple from a distance, she notes Chiho's outfit and salon-fresh hairstyle, quickly discerning that she is romantically interested in Maou. Despite Ashiya's assurances that his master was simply helping out a co-worker, Emi forces him into getting a table at the cafe so that they can spy on the conversation more closely, much to the Demon General's hesitance. Upon hearing Chiho confess her feelings, the hero confronts them openly, scornfully warning the teenage girl that nothing good will come of her relationship with Maou. Her words only anger Chiho, who begins to believe that Emi was his ex-girlfriend. The high school girl remains unaware of Maou's true identity, having only seen the kind-hearted personality he developed while on Earth.
Maou attempts to stop the ensuing argument, but his pleas are interrupted when the underground mall they were in suddenly collapses, burying everyone underneath the rubble. Chiho wakes up to an apologetic Emi, who formally introduces herself before calmly explaining her dislike of Mapu. While she does not reveal the existence of Ente Isla or the demons' true identities, the hero makes it clear that she was never on good terms with Maou. She then uses magic to put Chiho to sleep, hoping to lessen the emotional impact of the incident. Emi subsequently orders Maou to reveal himself, expressing surprise upon seeing that he had regained some of his demonic appearance and powers. Wary that he would use them for evil, Emi prepares to summon her Sacred Sword to cut him down, but cannot bring herself to do so when the Demon King announces his intention to save the others who were injured in the cave-in. She watches as Maou clears away the rubble with his powers, not able to believe that the Demon Lord that had thrown Ente Isla into chaos was helping humans.
Emi showed up the next morning at "Castle Overlord" to return some money Maou had lent her when she dropped her wallet. She lost her footing on the stairs when leaving, thus stayed to get her wounds treated. Seeing his warm and gentle nature for herself, the hero finally loses her composure, sadly questioning why someone capable of kindness had brutally terrorized Ente Isla. Left at a loss for words, Maou apologized for his past actions, claiming that he never truly understood humans until being forced to life as one. Before Emi could respond, Ashiya returns with Chiho, who becomes distressed upon seeing Maou and Emi in various states of dishevel, and subsequently flees the apartment. The group is then approached by the landlady, who openly muses over the situation, dropping a hint that Chiho may have been affected by an Idea Link at some point. Fearing for the worst, the trio follows after the high school student, only to find that she has been taken hostage by the fallen angel, Lucifer. Emilia is shocked to see him alive after supposedly killing the archdemon during their battle in Ente Isla, but her surprise turns to horror and betrayal when High Priest Olba emerges from nearby, revealing himself as Lucifer's accomplice. Before they can act, Alciel is struck down by the devious duo, forcing Emi and Maou to retreat with the injured demon in tow.
The group is quickly intercepted by Olba, who fires a gun into Maou's shoulder, heavily injuring the former Demon King. Emilia expresses surprise that he is using a firearm, but the rogue priest shrugs off the comment, claiming that he has to conserve his magic power in order to return to Ente Isla. Unwilling to provoke the situation further, Emi continues fleeing alongside her former enemy, rudely calling him a wimp while dismissing his foray into a crowded street as an attempt to find medical treatment. Before their bickering can escalate, Maou is blasted through the chest by an attack from Lucifer, seemingly killing him due to the frailness of his human body. Emi pleads with him to stand up, but the fallen archangel only mocks them while Olba gives the order to finish them off.
Emi is a strong-willed and powerful hero capable of wielding the sacred sword 'Better Half'. She is generally very kind and tries to do the best for other people, but due to her feud with the Demon Lord, she tends to be mean to him and resents his kindness. However, she admits that his kindness has helped her and others many times, and it is hinted that she may not completely dislike Maou. She is also extremely sensitive about her chest size, and is secretly envious of Chiho's.
Emi has long magenta hair that extends all the way down her thighs, with two strands hanging in front. The strands on the right are weaved into a small braid, while one particularly long strand of hair protrudes from the top of her head, forming a curl that dangles above her face. She has green eyes while in human form, and is shown to wear many different outfits in the human world, her most common outfit being the uniform she wears for work. Likewise her standard attire consists of a long-sleeved, white, collar shirt and a gray vest slightly open in the front to reveal the front of her shirt and the purple bow below her neckline. This attire is complete with a pair of high heels and a dark plaid skirt that cuts off a few inches above her knees, revealing the length of her legs.
As the hero of Ente Isla, she wears decorative silver armor with a golden trim that covers her torso, shoulders, and backside. There is a tiny opening right below her collar, below which is a golden crest situated above her breastplate, the bottom half of the armor opening in the front to show her waist, revealing a ruffled black skirt with white frills and leggings. Her knees and lower legs are clad in metallic boots with a similar look to her body armor, with matching arm-guards protecting her lower arms and elbows. While utilizing her full power, Emilia's hair turns a shade of bright silver and her eyes change to an orange hue. She can call forth her armor and sword at will, making the hero transformation almost instantaneously.
Back in Ente Isla, they were mortal enemies. On Earth, they still tend to be at odds with each other but on a smaller scale. She seems to be conflicted with her intention to kill Satan, having seen the compassion his human self is capable as compared to her idea of the Demon Lord in the past. They are currently raising Alas-Ramus as they had decided to be her parents; this has created many situations to bring them closer. In Volume 10 of the light novel, it is revealed that she has developed feelings for Maou, due to their time spent together.
During their first encounter, Emilia fought with the Demon General Alsiel, driving him into a retreat to the Demon Lord's Castle on the Central Continent. While having been mortal enemies back in Ente Isla, they share a cordial acquaintance on Earth, speaking to each other civilly despite a certain sense of dislike still lingering between them. Due to her hatred of the Demon King's past exploits back home, Emi does not hesitate to put down Maou in front of Ashiya, which aggravates him to no end. In addition to this, she also finds his frugal nature to be quite irritating, often pointing out his tightfisted habits, or exploiting them in order to coerce information from him.
Her friend and colleague at Dokodemo. Rika appreciates Emi for not prying into her past when she revealed that she's from Kobe.
They did not get off to a good start, as on their first meeting Emi warned Chiho about Maou's character and unwittingly mislead Chiho into thinking that she had a relationship with Maou. Now, she is on friendly terms with Chiho, the only human on earth that knows the true identity of the people from Ente Isla. At times, she gets jealous of Chiho's chest size.
Powers and AbilitiesEdit
In Ente Isla, she was known to be very powerful, able to single-handedly push back the demonic forces and fight the Demon Lord and his generals on equal grounds. In the human world, she still had some powers remaining, but had to preserve them so she had enough to open a Gate back to Ente Isla. Later, Emeralda provides her with a drink called Holy Vitamin Beta that would help replenish her magical reserves while on Earth.
The powers that she has revealed:
- Heavenly Flames: It was shown that it engulfed her blade with fire with enough power to strike down Urushihara. It is unknown if this is an inherent ability of the Better Half or if she can perform it with any weapon.
- Barrier Creation (unnamed): This protects the target from harm.
- Memory Manipulation (unnamed): By touching the target's forehead, she can erase a person's memories.
- Sleep Magic (unnamed): By touching the target's forehead, she can make someone fall asleep.
- Energy Projectiles: During the fight against Lucifer and Orba, Emi fired an energy projectile from her hand to counter Orba's surprise attack against Ashiya.
Emi is shown to be capable of flight, but its limitations (such as whether it uses up her Sacred Power or not) are not clear as of yet.
Her sacred sword, 'Better Half', is made from a heavenly metal (天銀 tianyin). It can only be used by the offspring of a human and angel. When taken by the Church of Ente Isla, Emilia started undergoing training in swordsmanship. Previously held in the possession of the Church, 'Better Half' was returned to her and she finally obtained the ability to defeat the Demon Lord as the Hero.
Emi's human body is more fragile on Earth than it is in Ente Isla, thus when she caught a falling Chiho, the impact sent her to her knees and broke the bones in her legs in the process. However, she could move and recover from her injuries soon after.
Enhanced Reflexes Edit
Emi is shown to be able to dodge multiple projectiles in close combat.
- Her original name "Emilia" means rival.
- Yusa sounds similar to yuusha, which means Hero in Japanese.
