Roy Alphard/Relationships

Family

Lye Batenkaitos

Despite the two being brothers, Roy doesn’t seem to necessarily care about Lye. In fact, he was often chastised by his brother for his way of thinking regarding food. Even after learning of Lye's death, Roy seemed indifferent about it.

Rui Arneb

Roy first met Rui after she took over Lye’s body. Though Roy seems to respect his sister and offer various meals to her, he doesn’t seem to be as attached and protective of her as his brother. What he thinks about his sister’s current predicament is unknown.

Witch Cult

Mother

As one of her “children,” Roy listens to her orders. In Priestella, Roy was the only Sin Archbishop to team up with his fellow Archbishops, acting as one of the obstacles towards reaching her.

Anastasia Camp

Julius Juukulius

Having accessed the name and memories of his brother, Roy knows Julius very well, channeling the emotions of his brother. In Arc 5, Roy and Julius encountered each other twice, once on top of the City Hall building and once at the second control tower. In both clashes, he showed this overfamiliarity with Julius, leaving him unnerved throughout the arc. In the end, Roy devoured Julius’s name and erased his existence from the world.

Later, after the soul of Reid Astrea, who had taken over his body, was defeated, Julius was the one to seal Roy after his body was left on the verge of death. He has yet to cough up Julius’s name.

Joshua Juukulius

Despite not being the one to devour his name and memories, Roy was the one to use his memories by pulling them from the Stomach of Souls.

Ricardo Welkin

Due to having eaten Joshua’s name and memories, he is very familiar with Ricardo, showing signs of respect as Joshua did. However, he also often called him a dog or mutt, claiming not caring much for such appetizers. During their fight, Roy managed to sever Ricardo’s arm.

Emilia Camp

Natsuki Subaru

Initially, Subaru’s hatred for Roy was very one-sided, as Subaru mistook Roy for the one to devour Rem’s name and memories. Later, when Rui was after Subaru’s body, he was given the same memories of Subaru that Rui had eaten, as implied by Reid’s disgust towards the boy after he took over Roy’s body and proceeded to attack the Pleiades Watchtower as per his sister’s orders to take care of him.

Priscilla Camp

Al

In Arc 9, Al helped Roy escape confinement, giving him the ultimatum of obeying so he wouldn't kill Roy. This resulted in the two clashing and Al, despite dying so many times, thrashing him and binding him with an oath bound curse mark. Al clearly despises the young Sin Archbishop, and if not for his being necessary for his plan to succeed, he would gladly have thrown him off of the Great Waterfall. On the other hand, while Roy was aware of Al through the memories that he'd eaten, he did not seem to care, and he enjoyed teasing and poking fun at him.

Others

Reid Astrea

Roy met Reid during the raid on the Pleiades Watchtower. Believing that Reid would be an exquisite dish, he attacked the first Sword Saint and was promptly defeated and brutalized. Soon after, Reid would allow him to devour him, allowing Reid to take over his body since it was too big for Roy to handle. Thanks to this and Reid’s “defeat,” Roy was left on the verge of death and sealed.
