Ram/Relationships

Rem
As Ram's last surviving family member, Ram cares greatly for her twin sister. Even as kids, Ram always encouraged her whenever she felt inferior or depressed. When Rem died in one of Subaru's loops, Ram fell into a fury, adamantly chasing Subaru down for suspecting him of being involved with Rem's death. However, after Rem's existence was temporarily erased by the Authority of Gluttony, Ram completely forgot about her sister and did not feel bothered by her falling into a coma. However, Ram does develop some of her previous care for Rem.

Al
Ram has some kind of past with Al, as his normally carefree attitude changed when he learned that she was still alive, and he later expressed his disgust at the thought.

Roswaal L Mathers
Ram does in fact know that Roswaal was the one behind the attack on her entire clan, but he was not directly responsible for their deaths. He merely gave out the order for their annihilation, and the Witch Cult did the rest. When Ram learned the truth, she was enraged and swore revenge. However, things did not turn out the way she expected them to and her anger eventually subsided, but Ram still put her sister Rem’s welfare above everything else, including her own life. Roswaal took advantage of this fact and used Rem to force Ram to enter into a contract with him. If she refused, Rem would die, which is why she reluctantly agreed to work at Roswaal’s mansion. Her anger at Roswaal for killing her clan had now turned into loathing for threatening Rem’s life.

After Rem's existence was temporarily erased by the Authority of Gluttony, Ram forgot all about the sister she loved and existed for. As such, her hatred toward Roswaal disappeared because now she did not have a reason to hate him. Without Rem in her mind to be threatened by Roswaal, and the fact that she did not care that much about her oni clan to begin with, she started to work more for Roswaal, and the more he cared for her and, the more she respected him.

Ram has complicated feelings for Roswaal. She definitely has more than mere platonic feelings toward him, but it's tough to say whether her obsession with him is due to her over-dependence on him or because she loves him and the novel shows how she is ready to give up not only her own life but Rem’s life as well just so that Roswaal could get what he wanted (which was killing Garfiel) Ram did hate how the Book of Wisdom took him down a dark path because she believed he was capable of being a genuinely good person, which is why she destroyed it at the end of Arc 4.

Roswaal saved Ram and Rem and took them under his roof so that they could help him realize his goal of killing the dragon; using her sister's horn through Synesthesia, Ram could achieve roughly the same potential as she had with her horn which would allow her to fight the Divine Dragon Volcanica.

Roswaal does feel emotionally attached to Ram and after the events in arc 4 the two have a better understanding of each other. It's possible that to a degree Roswaal may return her feelings but not anywhere near to the degree he still has for Echidna.

Natsuki Subaru
Although they are friends, there are times when Ram is direct and sentimentally cold with Subaru, sometimes even getting mad at him. Ram gets his name wrong on purpose; always calling him "Barusu" instead. However, she is also willing to help him when he needs it, such as when they fought the Wolgarms or when she taught him how to read and write. Ram often describes Subaru as a "man with good timing". Through Arc 4 friendship and higher respect is built between them, throughout the series the two become closer. Regardless, she was disgusted that Subaru had been hugging her in the dragon carriage while they were both unconscious, and upon being told about that, Ram was going to kill the still unconscious Subaru.

Emilia
Although Ram does not socialize much with Emilia, they have mutual respect toward each other, even if Ram thinks at times Emilia can be unreliable. As time passes, Ram starts to develop more respect and trust for Emilia despite her shortcomings.

Garfiel Tinsel
Despite her cold and often hostile demeanor, Ram can be seen caring for Garfiel and his well-being, going as far as helping him to face his past and overcome his fear of the outside world. Garfiel holds strong feelings towards Ram, even expressing his love for her and often going out of his way to compliment her or say something good about her, despite him always being turned down and often treated as nothing more than a distant acquaintance. In one of the lost Arc 4 loops when Roswaal stabbed both Ram and Garfiel, he risked his life to prioritize saving Ram despite knowing that they'll both die.
