Figure | Re: Zero Starting Life in Another World | Ram | FuRyu BiCute Bunnies Cutie Style

Ram is one of the twin maids who worked for Roswaal in the Re:Zero series. Rem and Ram are identical twins except for the color and parting of their hair. 

Ram has medium length light pink hair that covers her left eye, large darkish red eyes, and young features. She also has hair clips towards right side of her hair, flower-shaped ribbon on the same side of her hair, and a maid hairband. She looks nearly identical to her sister Rem, apart from her hair, eyes, and ribbon coloring. She usually wears a maid uniform. She has a smaller chest compared to her sister, and she has slanted eyes.

As the prodigious 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, as, according to the chief of the village, she was the second coming of the Oni God. Her aptitude didn't just lie there, she excelled in everything - from cooking to physical activities - 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 being 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. Roswaal would also ensure that Ram received regular mana infusions and served as her lifeline. During the early days of her life at Roswaal Manor, 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 its predictions as penance for knowing about the attack and letting it happen for his own ends.
