Ram

Ram (ラム) is Rem's sister and one of the twin maids working for Margrave Roswaal L Mathers. Debuting in Arc 2, Ram originally played a rather neutral role, neither assisting in Subaru's endeavours or directly going against him, like her sister–save for one of the failed loops where Rem succumbed to the curse. In the arc's final loop, however, she played a vital role, allowing Subaru to prevail and stop the Demon Beast rampage in the forest. Ram has also played a vital supporting role in Arc 4 and Arc 6, dueling Roswaal in the former Arc and the Sin Archbishop of Gluttony in the latter Arc.

Originally, Ram was born into the Oni Clan with a single horn and displayed exceptional talent and strength which resulted in the village referring to her as the second coming of the Oni God. However, after an attack orchestrated by the Witch Cult, she lost her horn and–together with her sister–was saved by Roswaal L Mathers. In return, Ram swore to help Roswaal in his own endeavours, pledging to help him kill the Divine Dragon. During her ten years of serving under the Margave, she developed strong feelings of love for him, despite initially vowing to kill him and avenge her slaughtered Clan.

Appearance
Ram was identical to Rem in every aspect, with the exception of her eyes, the color of her hair, and the size of her breasts. Her pink hair was cut into a short bob and parted to fall over her left eye, as opposed to Rem whose hair fell over her right eye. Her large dark-pink eyes, pink lips, and soft skin gave Ram a youthful loveliness that Natsuki Subaru found both beautiful and adorable when he first saw her. Ram noticeably had a smaller breast size than her younger sister. As previously mentioned, Ram's eyes were different to Rem's, as the elder sister's were slightly more slanted. Her delicate frame featured narrow shoulders and stood at one-hundred and fifty-hours centimeters tall (or five foot one).

Judging off of her appearance, Ram inherited the color of her eyes from her mother and the shape of them from her father. She also clearly inherited the natural shape of her hair from her father and the color of her hair from her mother. Ram, as a demon, could manifest a small curved-horn on the center of her forehead that was made out of pure pink energy. When her village was destroyed, Ram's horn was sliced off, leaving an obscured slit-like scar on her head where it used to be.

Most of the time, Ram wore a uniform issued to her as part of her job in Roswaal's mansion. This maid outfit consisted of a short black dress with white flowery accents, a white apron, white thigh-high socks, black Mary Jane shoes, and a white-and-black flowery headpiece. The outfit exposed Ram's shoulders and flaunted her body line in a provocative way, leading Natsuki to believe the designer's intentions weren't entirely pure. Positioned on the right side of her head, Ram had a purple hair-clip and a flower-shaped ribbon of the same color.

Personality
Ram is seemingly self-centered and does things at her own pace, however in actuality she maintains a distance from people to ascertain them. She believes that Roswaal is the greatest and no one else is as precious except for her sister Rem. She is slightly more outgoing in comparison to the generally taciturn Rem, who generally allows Ram to take the lead in their sisterly bond.

Ram is extremely loyal to Roswaal L. Mathers, threatening others (namely Subaru) with violence, should they endanger or badmouth him. Over the course of the series, it's evident that Ram has developed feelings for Roswaal.

History
The Oni Ram and her younger twin sister Rem were born in a small Oni village located in the Kingdom of Lugnica. In adherence to Oni law, the elderly chief of the village Setanta sentenced the infant twins to death. Both the mother Temae and the father Quark desperately begged for Setanta to spare the lives of their children, yet the stern old man chose to adhere to the law and execute the cursed twins. The children were placed on a shrine in the middle of the village surrounded by braziers that allowed the whole village to witness the deed at the dead of night. As Tamae screamed for the village to spare them Setanta prepared his singular attack to dispose of the children. Ram, hearing the cries of her sister laying beside her, demonstrated her power. In spite of being a mindless child, Ram used her mana from the atmosphere to summon a massive torrent of wind that knocked the chief from his feet. After a brief moment of shock, every villager including the chief knelt before the pink-eyed child, firmly believing her to be the reincarnation of the oni god. As such, both twins were allowed to live.

As the prodigal elder twin Ram was born with extraordinary talent for mana manipulation and a powerful body to match that made her the pride of the Oni village. Her aptitude didn't just lie there, everything from cooking to physical activities she was superior to Rem and was showered in adoration even by her own sister. However she never let any of it get to her head and never forgot her little sister no matter how much attention was paid to her. During the night of the attack by the Witch Cult when all the Oni fell she alone kept fighting to avenge them and protect her sister. But the cult outnumbered her and she made a last ditch effort to shield a petrified Rem from getting cut down. In mere moments, Ram lost her horn when it was sliced off from her head as a result of that. Had it not been for a passing mage at the time whom they came to know as Roswaal L Mathers they would not have survived the massacre.

The next several years since then Roswaal would gain the twins eternal gratitude and fervent loyalty. Especially in the case of Ram who came to harbor romantic feelings for him who also served as her lifeline due to regular mana infusions. During the early days of her life in Roswaal's mansion Ram would also come to know the partial truth of the cult's raid that night as well as the identity of the cult member responsible for cutting off her horn, Faust with assistance from Roswaal and achieved her vengeance. Ram is the only person who knows about Roswaal's gospel and had formed a contract with him that stipulated that his life would be hers if the future ever deviated from it's predictions as penance for knowing about the attack and letting it happen for his own ends.

Abilities
Clairvoyance (千里眼 Senrigan): A secret art passed down through generations in the Oni tribe. It enables her to synchronize with the vision of those who have the same wavelength, allowing her to overlap her vision with another being. While she's usually able to synchronize her vision with anyone she wishes to, there are a few exceptions, one of which being "high-ranking" individuals such as Roswaal. If such people close off their heart, Ram is unable to use Clairvoyance on them. Although she is unable to defend herself while using it, it allows her to continuously switch between people, making her actually able to see past one thousand ri. However, the side effect of the ability causes her veins to become prominent, shed tears of blood from one eye, and legs to shake uncontrollably.

Magic User: Ram is able to use Wind Magic and is mentioned to be relatively skilled in it.
 * Fura (フーラ): Fura is Ram's most used Wind Magic. Ram shoots wind slashes with a super high speed that can cut through wood, stone and flesh with ease.
 * El Fura (エル・フーラ): Ram unleashes a extreme blast of magical wind. Ram_using_El_Fula.gif
 * UI Fura (フーラ): Ram creates a windstorm with the target in the middle, the raging wind strikes the target, slices them, tosses them, smashes them against the ground, and then flung so thoroughly they cannot discern up from down.
 * Al Fura (アル・フーラ): The user unleashes a wild devastating windstorm so powerful even people's eardrums will be destroyed in its mere presence.

Synesthesia: An ability that she shares with her sister. It allows them to share their feelings and emotions with each other through telepathy. Ram is even able to borrow Rem's horn and use it to greatly amplify her own fighting strength.

Oni Bloodline (鬼の血族 Oni no Ketsuzoku): Ram was formerly considered to be a child prodigy and the second coming of the Oni God even though she only had one horn, however it was cut off by Faust when the Witch Cult attacked her village. Despite not having a horn, she can still go into her Oni Form, being able to use her powers to greatly boost her combat abilities for a short amount of time but at a cost of vomiting blood and rendering herself unable to move for a long period of time. It is stated that she manages this form in terms of "Shackles", with each shackle representing around 10% of her power as an Oni.

Martial arts: Ram is shown to be very skilled at hand-to-hand combat and has an exceptional awareness of her own body's limits. Her knee kicks and elbow punches are capable of shattering bones and rupturing internal organs and by using Wind Magic, she is able to amplify the speed and direction of her attacks, making her an extremely proficient opponent who's able to go toe-to-toe with the likes of transformed Garfiel and Lye Batenkaitos.

Equipment: Ram usually uses a Wand Roswaal fashioned from her horn when fighting. It helps her better channel her mana to reduce the burden of using magic. During the events of Arc 3, Ram uses the wand while fighting Wilhelm and Ricardo in close combat. The wand is described as looking like a short cane.
