Roswaal L. Mathers/Relationships

Family

Beatrice

Both of them are acquainted with each other for more than 400 years, as they were both under Echidna's mentorship and protection. Before Echidna's demise, Beatrice formed a pact with her and vowed to protect the Forbidden Library located at Roswaal Manor. After Echidna's demise, Beatrice shut herself into the library, spending all of her time in there. Despite that, Roswaal still kept on visiting her, even after the original Roswaal A. Mathers "died". He never confessed to her that he was the original Roswaal inhabiting the bodies of his descendants so their relationship became one between strangers. In reality, Roswaal loved Beatrice deeply and truly cherished her and the relationship they had, and viewed her as family despite Beatrice distancing herself. As expected, he would sacrifice her for his grand goal, despite the fondness he had of her, although according to Clind, Beatrice is his weakness. His only regret is how cold her attitude is towards him.

Ryuzu Meyer

Ryuzu and Roswaal were classmates being taught by Echidna. They were also very close friends.

Dudley and Grace Miload

Though a part of the Miload branch family, Dudley and Grace were on good terms with Roswaal. Likewise, Roswaal was saddened by their deaths at the hands of the Witch Cult. In particular, when Grace died, she entrusted her child to Roswaal.

Annerose Miload

Roswaal has been impressed with Annerose’s maturity and ability to deal with both him and the political world. In the Greed IF, he states that Annerose is the next body for him to take over, but as of yet, it has not been stated in the main story, so whether it remains canon is also unknown.

Emilia Camp

Clind

Clind and Roswaal have known each other for at least 400 years. In the distant past, they forged a contract which entailed defeating an unknown enemy of Roswaal's as well as the protection of his property. Due to him sensing the soul of the original Roswaal within his descendants, he has abided by the contract ever since. It should also be noted that Roswaal is aware of Clind’s authority, and he has often had to make use of it, even giving up something as important as certain magics so that Clind could use it when he believed it was necessary.

Ram

Through his Book of Wisdom, Roswaal prematurely learned of the incoming Witch Cult attack on the hidden Oni Village, however, he chose to follow the Book's writ and not prevent it. Further acting on the Book's instructions, Roswaal proceeded to save Ram and Rem, effectively making them the only two survivors of that village. When Ram learned the truth, she was enraged and swore to take revenge in the name of her wiped-out clan. However, things did not turn out the way she expected them to and her anger eventually subsided. Roswaal and Ram formed a contract, which binded Ram to help Roswaal with his schemes of killing the Dragon. In exchange, she could do whatever she desired with him once he had achieved his goal or whenever he surmised that the prophecy in his copy of the Book of Wisdom would not come to pass in the current world.

Roswaal took in Ram and Rem under his wing and is shown to deeply care for their well-beings. He oftentimes used Ram as an informant on matters, which showed the level of their mutual trust. Despite this, he has no qualms on sacrificing her to meet his goals as shown in one of Arc 4's failed loops, where he kills Garfiel, despite Ram being in the way. It is worth noting however that he knew he was going to die, and that Subaru would loop to bring her back anyway.

Throughout the years, Ram's hate for Roswaal slowly dissipated and turned into feelings of affection and love. During Arc 4's climax, Ram ended up confessing her feelings for him, which shook him to his core. Since his feelings hadn't change for the last 400 years, he assumed that Ram's hadn't changed either. However, it is shown that he is emotionally attached to her.

Rem

Roswaal took Rem and Ram under his wing and was shown to deeply care for them, as seen when Rem died of unknown causes and he immediately suspected that Subaru is responsible (he was even prepared to kill him, much like Ram). While she is dutiful, unlike Ram, Rem has no strong loyalty towards Roswaal. Her obedience is borne more from his necessity to Ram's condition and being the owner of their new home she wants to protect.

In Arc 6, it is implied that the main point in Roswaal also taking Rem under his wing is for her ability to act as Ram’s horn so that she can exert her full power when the time comes.

Frederica Baumann

Frederica was a maid for Roswaal around ten years ago. As such, she became familiar with the man’s demeanor and was willing to assist him. In Arc 4, she would return to aid him when Rem’s name and memories were eaten, and she even followed the orders he left her in a letter. That said, following the events of Arc 4, she thought negatively of his actions, and she has come to speak her mind more often to him, sometimes even calling out his suggestions when they seemed mad, as seen in Arc 8. Ultimately, the two are on rather friendly terms even after Arc 4.

Garfiel Tinzel

Garfiel never trusted Roswaal, and his actions during the business in the Sanctuary only made things worse. However, Garfiel recognizes Roswaal’s strengths and knows that the camp needs him. Still, anytime Roswaal was present, he kept his guard up and actively made visible his spite.

On the contrary, Roswaal seems not to have any negative feelings towards Garfiel, and he is even willing to give him guidance in combat, such as in the case of confronting Olbart Dunkelkenn in Lupugana. However, it should also be noted that he has no qualms with killing the boy if he deems it necessary, as shown in the final failed loop of Arc 4.

Emilia

Emilia's benefactor and backer in her bid to acquire the throne. He's considered an odd lord, especially due to his fondness for demi-humans like her to the point where he would hire them. In truth, he is only actually using her to control Subaru and coerce him into using Return by Death to fulfill his ambition of reviving his late master through the wits of his Gospel. To do so, he needs a guaranteed way to put Emilia on the throne because he has no faith in Emilia's resolve to overcome her past and deeply-rooted hatred of the Witch of Envy. However, with the encouragement and support of Subaru and several others, Emilia shatters his expectations by passing all 3 of Echidna's trials. He is then forced into backing her earnestly.

Puck

The two would “first” meet when Roswaal would come to coerce Emilia into being involved in the Royal Selection. However, he and Puck would enter combat since he didn’t trust the man’s intentions. However, the two would ultimately reach a truce. That said, Puck was still wary of the Margrave and suspected ulterior motives, something which would prove true once Subaru entered the picture.

However, during the events of Arc 4, Puck would recover his memories after severing his contract with Emilia. As he and Ram entered combat with Roswaal, it seems that Puck has picked up on his true identity as Altair Mathers, referencing his past with Echidna and Hector, going so far as to claim that Roswaal will never be like “that Warlock.”

Natsuki Subaru

When they first met, Roswaal appeared to be genuinely grateful for Subaru rescuing Emilia's insignia, even offering him anything he wants as gratitude. He appears to be rather friendly to the young boy. However, Roswaal is more than prepared to kill Subaru in one of the loops, connecting him to be the cause of Rem's unknown death.

In Arc 4, their relationship became rather antagonistic with Roswaal giving Subaru half-truths or intentionally throwing monkey wrenches in the latter's plan. In said arc, it is revealed that he had discovered Subaru through his Tome of Wisdom, believing his ability to travel back in time to be heavily useful for his purposes, and the events of Arc 1, several events in relation to Arc 3, and Arc 4 were all tapered in a way to push Subaru into becoming a Sage, something he believes as necessary to achieve his goals.

Ultimately, the two would make a bet that would result in Subaru’s win, and Roswaal would give himself an Oath Curse that would burn his soul if he broke said oath. That said, he would be more than willing to break this curse and kill everyone if Subaru made even one mistake, forcing him to use his Authority. Because of this, he and Subaru have a rough relationship, but Subaru believes him necessary for the Emilia Camp’s victory, and he leaves issues in politics in his hands.

Since Roswaal still believes Subaru is necessary for his goals, he would become somewhat desperate if he found himself in a precarious situation, such as in Arc 7 when Subaru had been teleported to Vollachia. Because of this, he would arrange things so that the camp could infiltrate the country in order to retrieve him. Similarly, he would also go along with Subaru’s antics to keep him appeased. For example, in Arc 7, when he learned that Subaru was on the side of the rebels, Roswaal was more than willing to kill Serena Dracroy, an old friend, if she stood in his and the rebellion’s way. Later, in Arc 8, he would also be one of the people backing every decision Subaru made in regards to saving Vollachia and keeping Spica by their side, the latter of which causing immense distress to certain other members of the camp.

Otto Suwen

Roswaal and Otto have a rather negative relationship. Though they are both intelligent and are often involved in the camp’s major decisions, due to Roswaal’s actions in Arc 4, Otto is severely distrusting of the man, even with the Oath Curse. This distrust, fueled by his desire to keep everyone safe, would be so strong that he would go out of his way to bring Roswaal’s burned Tome of Wisdom to a restorer named Dartz so that he could read everything that Roswaal had read in an attempt to predict the Margrave’s plan.

Meanwhile, Roswaal at first thought nothing of Otto since he didn’t appear in his Tome of Wisdom. However, he recognizes the merchant’s capabilities, and like the rest of the camp, he believes Otto as the most dangerous member of the camp. That said, he also wants to make Otto go along with Subaru’s and Emilia’s decisions without a fuss, as seen when he attempted and failed to manipulate him in Arc 8 when he was frustrated regarding the decision about Spica.

Petra Leyte

Initially, as a resident of Arlam Village, Petra was protected under the Margrave’s authority, though she always seemed to think of him as strange. Despite this, she would still apply to become his maid (to be closer to Subaru). Due to the events of Arc 4, she bears a deep grudge against him, and she does not trust him in the least. Over the course of the following year, she would make her hatred for him visible, often leaving needles in his clothes, spilling his tea, or even wringing out dirty water in his tea. Despite this, however, she is still learning from the man how to handle politics and magic.

As for Roswaal, he does not mind her attitude towards him, and he is even willing to defend her from accusations accosted by the nobles.

Anastasia Camp

Julius Juukulius

It is unknown what Roswaal thought of Julius before his name was devoured. However, when the two met, he instantly recognized the issue, and he even recognized his talent, as he would come to request Julius to take care of Ram for him. Though Julius was apologetic that he couldn’t help at the time, he showed full willingness to accept his request were he able.

Nine Divine Generals

Olbart Dunkelkenn

Although they would meet for the first time during the Decisive Battle for Lupugana, Roswaal instantly recognized who he was and the threat level that he posed. Likewise, Olbart was wary of him and found him to be difficult to deal with.

Balleroy Temeglyph

During a meeting in the past regarding how to handle Vollachia, Roswaal recognized Balleroy as one of the biggest threats and sought to create countermeasures against him. However, Balleroy would end up dying several months before the start of the story. Ironically, however, Roswaal would get a chance to confront the man during the Great Disaster, where the Magic Bullet Sharpshooter would be brought back to life as a zombie. During their clash, Roswaal stated that under ordinary circumstances, Roswaal would lose to Balleroy. Conversely, Balleroy despised the way Roswaal handled their fight, using Medium, as a practical meat shield, and throwing out numerous attacks with various targets simply to divert the man’s attention.

Vollachians

Serena Dracroy

Having once assisted Serena in the past, the two became friends. When the two met again in Arc 7, she even made a jab at his nickname, the Demi-Human Lover, as a joke. However, it should be noted that he is not afraid of coming to blows if she stands in the way of his goals (i.e. Subaru being trapped in Vollachia). Fortunately, there was no need for this to happen.

Witches

Echidna

Years before the Great Calamity, Echidna encountered young Roswaal who was unable to utilize his insane magical talent and potential and was being treated as a sickly nuisance by everyone who encountered him as back then, magic was very much misunderstood and mages weren't as renowned as they are now (with few exceptions). Echidna sensed his ability and potentially devastating power and decided to take him under her mentorship, teaching him how to properly use magic and opening Roswaal's eyes, allowing him to recognize that his body isn't a "danger" but a "gift", allowing him to prevail and learn how to effectively use all six magical elements. As a result, Roswaal harbored intense and deep feelings for her, which were unfortunately very one-sided as Echidna is unable to comprehend human emotions. She was the most important person to him. After her death, Roswaal became obsessed with reviving her, even being prepared to give his life in order to achieve his desired future, kill the Dragon and cross paths with Echidna once more.

Hector

Hector and Roswaal used to share an extremely hostile relationship. Roughly 400 years ago, Hector pursued Echidna and located her at her hideout in the Sanctuary. Roswaal faced off against him, trying to fend him off and protect the Sanctuary but he failed miserably, being one step away from death. At the last second, Echidna came to the rescue, saving Roswaal's life but at a cost of his ego being utterly shattered. In the following years after his defeat, Roswaal started wearing the same clothes and talk in the same manner as Hector, in order to not forget the humiliation he suffered all those years ago.

Sphinx

When Sphinx made her presence known during the Demi-Human War, Roswaal, who at the time was in the body of Roswaal J. Mathers, actively sought her out, learning martial arts solely to counter the Witch’s magical prowess. Though Roswaal would not land the finishing blow on Sphinx, he was led to believe that the failure of Echidna was dead.

In Arc 8, Roswaal would encounter the zombie of Sphinx while intending to study the bodies of the zombies with Beatrice. Naturally, his hatred for the Witch started to boil within him, and when Sphinx would not answer him, he quickly engaged in combat against her, destroying this body alongside Beatrice and Garfiel. When he saw her again later in her new form as the Witch of Greed, he immediately realized that she was Sphinx, and he even claimed that she didn’t even look like Echidna.

Others

Volcanica

Roswaal’s primary goal is the death of the dragon, though it is for unknown reason. Considering Volcanica ordered the Mathers family to handle the Witch of Greed’s remains, he may have perhaps met a young Altair once in the past. However, this remains to be seen.
