Re: Zero Reverse Isekai | Rem in your world

Rem is a maid in service of Margrave Roswaal L. Mathers alongside her sister, Ram. She is one of the main supporting characters of Re:Zero, with major roles in Arc 2, Arc 3, and Arc 7, and a supporting role in Arc 8, Arc 9, and Arc 10. During the first half of Arc 2, she was the secondary antagonist.

Born the younger twin of Ram, Rem, having an inferiority complex, was attached to and only relied on her sister, caring for no other. Following her sister after the destruction of her home with the Oni Tribe, she became a maid of the Roswaal Manor, working hard to bear the burden that her sister no longer can with the intent of becoming her horn in her place.[5] However, she began to open up after Natsuki Subaru's arrival to the mansion, falling for him. At the end of Arc 3, she had her name and memories eaten by Lye Batenkaitos and subsequently fell into suspended animation. She later awoke at the end of Arc 6 bearing amnesia.

Rem has medium-length sky blue hair that covers her right eye, large light blue eyes, and young features. She also has hair clips towards the left side of her hair, a flower-shaped ribbon on the same side of her hair, and a maid hairband. She looks nearly identical to her sister apart from her hair, eyes, and ribbon coloring. She usually wears a maid uniform, and since her chest is slightly larger than her sister's, she secretly changes the measurements to hide it. She has a uniform made for cold times, which has warmer cuffs around the wrists and covers her shoulders, and she also has one that she wears for her days off, that has more black than white, covers her shoulders, has shorter sleeves, and is closer to being a regular dress.

In Arc 6, Rem was dressed in a long-sleeved pink dress with white frills at the hem of the long skirt, pink boots, brown corset with three belts (two in the anime), black leggings, and a pink cloak to protect her from the sands of the Augria Sand Dunes. She continues to wear this uniform until her return to Lugunica.

When she was young, she wore a white kimono and a pair of zoris, a native dress of the onis, and her hair was styled the same as in the present day. After joining Roswaal Manor's staff, she began to don her maid uniform.

In the Sloth IF side story, Rem had grown her hair out long, had a flower shaped hair piece on her head, and wore a white kimono.

Rem is a competent, loyal person who always tries her best. Initially, in public, Rem is someone who maintains an emotionless expression, not displaying feelings like sadness or anger to maintain formality. She speaks politely to others, even if she dislikes them internally. Additionally, she possesses a sharp tongue and can unknowingly say blunt or critical things to the people she interacts with. While calm on the surface, in intense situations, Rem often gets tunnel vision and locks onto a singular objective. She tends to try to do everything on her own, bearing the burden of everything on her shoulders. Initially, from her perspective, only Ram and things directly related to Ram were important. This leads Rem to make rash decisions to protect her community, without needing to think twice about the situation. Working at Roswaal Manor, she also holds respect for its master, having been thankful for his actions towards demi-humans. More than anything, due to the way she grew up, Rem harbored excessive feelings of attachment, gratitude, and respect towards her older twin sister, Ram. Because she was always alone, her sister's care became a source of comfort, yet at the same time, something that caused her to feel as if she was suffocating. She is fully aware of how extraordinary her sister is, which she looks up to her for, but at the same time, not being able to understand the things that she can have made her feel worthless. Throughout her life, she constantly put herself down while propping her sister up, which, combined with the fact that she was born with one horn and was significantly weaker than her brethren, has led to an inferiority complex, and this complex deepened as a result of her guilt from feeling the slightest hint of joy after her sister's horn was severed, leading her to aim for becoming a perfect servant to atone for what she felt she had robbed from Ram. This also leads her to understand others who have a similar complex, like Frederica Baumann has about her teeth. Burdened by a sense of atonement toward Ram, she overworks herself, doing things in a way she believes her sister would.

Despite what happened to her village, though she was saddened by their deaths, she harbored little sorrow for the deaths of her kinsmen, having been grateful that she still had her sister, and the only reason she initially agreed to take revenge with Ram was for Ram's sake rather than her own. During her time at Roswaal Manor, though her sense of inferiority and guilt never diminished, she felt more fulfilled than she ever did in her village, which weighed heavily on her conscience, as she was aware the only reason this was the case was because her kinsmen were killed. Simultaneously, her anger and attachment toward getting the revenge that her sister desired also diminished, as she was becoming happier while living at the manor. That being said, her sense of hatred will resurge when put into said environment. Because of this incident, she has a deep sense of hatred for the Witch Cult and believes that nothing good can come from the Witch’s scent, and upon smelling it in her youth, she became quick to act, vengeful, and highly aggressive, to the point that she was willing to torture a man to death to draw out information about his co-conspirators. Even in the present day, that loathing led her to suspect, torture, and even kill Subaru on one occasion, as she suspected him to be a member of the Witch Cult because of his strange behavior and the scent wafting from him.

Thanks to the assistance of Subaru, Rem’s narrow worldview began to expand. No longer thinking of herself as her sister’s substitute, she started developing stronger bonds with the people around her. Rem felt grateful to Subaru for helping her move forward and developed a deep love for him, becoming one of his most loyal followers, to the point that she always believes in him as her "hero" no matter what, even if Subaru himself for some reason loses faith in his abilities, thereby serving him as an important emotional support even when she is not around, though she still maintains a low opinion of herself and can fall back into self-deprecation when comparing herself to Ram. It is because of this that she started to understand Garfiel Tinzel's behavior when he was around her sister, which she at first did not understand. After her confession, she becomes more open and honest about her feelings for Subaru. She boldly declares her love to the people around her. Her heart opened in a true sense, and she diminished the emotional restrictions she once had. Likewise, Rem displays great protectiveness, healing and defending Crusch against Regulus and Lye, two Sin Archbishops, even though her loss was certain.

After having awoken from her year and a half slumber, Rem acquired amnesia which left her in a state similar to that of Crusch at the end of Arc 3. In this state, rather than referring to herself by her name as she had before, she referred herself with I or my (私, watashi), and she tended to refer to Subaru as that person. She was very wary of everyone, especially Subaru, even going as far as trying to strangle him twice and set up decoy paths and traps in order to get away from him, as she considered him dangerous due to a combination of the overwhelming Witch's Scent seeping from him after his numerous deaths, as well as his resentment for Spica and refusal to help her in her current state, as Rem saw her as just an innocent child.

After some time, she became less wary of those around her, and she came to accept her name as her own, despite initially not feeling as though it was. She often showed kindness to people like Katya Aurélie, acting similarly to how Subaru was to her as Katya tried to push her away, and she has shown to similar fondness to Ram as she used to. Thanks to Subaru's influence, she became willing to take gambles during times when her situation was uncertain, including taking irrational options when provided with rational options, and thanks to Priscilla Barielle, her sense of self became stronger. Though she still acts particularly harsh towards Subaru, she has also shown her protective side as well, going out of her way to attack Todd when he was in danger, as well as a slightly envious side, which she displayed numerous times when he interacted with Emilia. She has shown to dislike how he takes on burdens by himself, and she still feels guilt about the way she acted around him, to the point that she feels she must make up for it before she can truly apologize.

Abilities Overall Power Rem's strength is such that she could easily hunt down and slay witchbeasts without coming to harm, and against average opponents, she is likely to win. It has been said that she is even capable of going toe to toe with a Guiltylowe. However, her strength is limited, and she can easily be overwhelmed by superior opponents or greater numbers of experienced fighters. This being said, what makes her the most dangerous is that, even in spite disadvantages against her, she has the will to keep fighting in spite of any injuries she may receive, and she will bring down as many enemies as she can with her before she falls.

Physical Traits/Flow Method Enhanced Strength: As an oni, Rem's physical strength is greater than the average person. It allows her to swing around a heavy morningstar with ease.

Horn: As she is an oni, Rem can enter her oni form, manifesting a single white horn on her forehead. In this state, her physical capabilities are enhanced further. As a twin, however, Rem was born with a single horn that appeared smaller than an average oni's, meaning her power in her oni state was lower than her kin's.

Further Enhanced Strength: With her horn manifested, she is capable of killing witchbeasts with her bare fists and showed no strain in carrying Subaru. Even as a child, she was capable of crushing the heads of fully grown men by slamming the hilt of her weapon into them or shatter a knife with a bite. Blade-like Nails: While enhanced by her horn, her nails become sharp enough that they can easily rend through flesh. Limited Regeneration: While her horn protrudes from her head, her body's regenerative capabilities are increased. Although not absolute or perfect, it can prevent her from racking up too many wounds at once. Combined with her healing magic, she can avoid fatal attacks much easier. Increased Ferocity: Manifesting her horn is a double-edged sword due to its traits of enhancing Rem's ferocity. She enters an adrenaline-like state in which she can keep fighting and killing her enemies, but if she is not careful, she could lose herself to her instincts and try to kill everything in sight. Furthermore, if she overexerts herself while her horn is manifested, it is likely that the recoil would render her weak. Horn Substitution: Being Ram’s twin, Rem can temporarily act as her horn and give her access to more of her power. However, doing so interferes with her body’s internal mana circulation, which once made it difficult for her to use her legs for months. Heightened Mana Sensitivity: During the events of Arc 9, with her horn protruding from her head and absorbing mana, Rem's sensitivity to changes in it became heightened. During her battle with Yae Tenzen, she realized her potential with this and had become capable of sensing intent through the emotional changes that are hidden in mana, allowing Rem to defend or act appropriately when in the face of unexpected or unseen attacks. The greater her opponent's bloodlust, the more sensitive she was to it, allowing her to react quicker. This also allowed her to determine the intent of her allies by perceiving their mana, allowing her to react appropriately even without words. Since Subaru has changed the events leading to this ability's awakening, she does not retain this ability. Miasma-Attuned Olfaction: Rem can smell the miasma that wafts from sources such as Witch Cultists and magical miasma stones, as well as the Witch's Scent that stems from Subaru's connection to Satella, something that only a few individuals in the series so far, are capable of doing. It is currently unknown how Rem is capable of doing this, though it most likely stems from the night her village was attacked and destroyed by the Witch Cult, as prior to that event, Rem never displayed such an ability. It is revealed by Echidna in Re:IF Kasaneru that this is a natural ability of the Oni Tribe as well as their purpose for existing despite the fact that her sister does not appear to possess this power.

Magic Rem has an affinity for the water attribute, and though not to the extent of Aldebaran with his earth magic or Emilia with her ice-based fire magic, Rem is rather creative in how she uses her magic. Roswaal, who taught her how to use it, estimates her skills being above average but nothing exceptional. She is able to attack and heal using her magic, and according to Puck, she has a habit of using her magic with wild and reckless abandon.

Healing Magic: Rem summons water mana to heal the wounds of herself and others. However, while she is skilled in treating external injuries, she is not so skilled at treating internal injuries, including the healing of the Gate. Huma: Rem creates a shining water barrier that blocks other projectiles and sorts of magic. However, if the incoming magic is stronger than the shield, it will get through it and cause damage to the user. She can also shape her ice in any manner she needs to, similar to how Aldebaran uses his earth magic, such as creating midair platforms, wrapping ice around her neck for defense, or creating layers of ice to increase the weight and power of her morningstar. El Huma: Rem forms and shoots multitudes of ice spears which easily pierces through and crushes flesh that vanish a moment afterwards. She is also able to freeze liquid such as blood, effectively creating deadly spikes out of her enemies' blood, impaling unsuspecting foes. Ul Huma: Rem materializes and shoots three pillars of ice, each as thick as a hundred spears bundled together. Al Huma: Rem creates a sharp ten-meter-long spear of ice.

Synesthesia: An ability that she shares with her sister. It allows them to share their feelings with each other, something which can allow them to alert the other of possible danger. If Ram is in intense danger, such as being on the verge of death, Rem will feel those feelings as well, something which will make her feel pain and pant, such as in one failed loop. This ability also allows the two to sense each other over larger distances, albeit vaguely. Most importantly, however, this allows Rem to share Ram's burden when she needs to access more of her power, essentially allowing her to act as Ram's "horn". This being said, the one time this was shown to happen, Rem was unable to use her legs properly, as her internal mana circulation had been greatly disturbed.

Morningstar: Rem wields a giant metal spiked ball on long metal chains called a morningstar. Rem is easily capable of causing significant damage to her target with it, whether that be tearing limbs from a person's body or even smashing their heads into paste. She can also use the chains for defense, using them to help deflect attacks. Even after she fell asleep for more than a year, Subaru kept her morningstar polished and clean to ensure it did not become damaged. Walking Stick: During the events of Arc 7, due to the complications with her legs throughout the arc, Rem was forced to use a long cane-like walking stick whenever she walked. She eventually stopped using it once she was able to walk on her own. Sword: For a short period during Arc 7, Rem used a sword in place of her walking stick and to defend herself from enemies. However, the sword was ultimately discarded.
