Background
She was a descendant of the nobles who supervised the Assault Gardens. Six years ago, her family was slain by the Voids. The commanding Void Lord went on a large-scale Stampede, attacking the Third Assault Garden, which happened to be near the city where her parents and older sister served as governors and Holy Swordsmen, commanding the knights. They’d gone to the front lines to halt the advance of the Voids and to protect the people. They’d all died in battle. She was nine years old at the time, and only she and her childhood friend Regina managed to evacuate to the shelter and survive. After that both of them got enrolled in Excalibur Academy.

While on a mission, Riselia and Regina went to great ruins in search of Voids. Riselia happened to found Leonis in the casket. She took responsibility of taking care of him. When they are getting out of the ruins, a Void confronts them. In the series of events, she died while protecting Leonis. Unknown for her, Leonis with sorcery resurrected her and being like him. She got to know this when she felt extreme tired and Leonis told the truth; she now becomes Vampire Queen.

Holy Sword
She awakes her holy sword in a mock battle between her and Leonis with Muselle Rhodes's platoon. Before possessing her holy sword, she practices everyday so her swordsmanship is fairly great.

Vampire Queen Power
She is a vampire queen, meaning that she can't die from normal hits. Unlike normal vampires, she is not afraid of sunlight, so she can go outside during the day. She now doesn't need to eat to gain nutrition, only needs to suck little blood to survive.

Leadership
Riselia is a capable leader.

Leonis Death Magnus
They first meet each other in great ruins where Leonis was sleeping for a thousand years. When Riselia finds Leonis in ruins, she gets shocked and concludes that Leonis was captured by voids, she was also impressed by his facial features and cuteness and showed a liking to him. She cares for him and decides to take him to Excalibur Academy. During his rescue, Riselia tries to save Leonis from void, so he can escape while getting killed in the process, showing that she cares Leonis more than her own life. When Leonis first meets Riselia his eyes opens wide, and he compares her beauty with a High Elf, on the other hand he decides to keep his identity secret to get information about human society but after seeing Riselia sacrifice to save his life, Leonis decides to save Riselia therefore using sorcery to resurrect her. Leonis resurrected Riselia as a vampire queen. When he reveals this to her, she is shocked, however, she quickly regains her composure after Leonis promised to train her so she can protect her love ones. Riselia's only concern, is the fact that Leonis may force her to have sex with him, something he promised he would never do. Despite everything, Riselia loves taking care of Leonis, usually she is the one who feeds him at meals and usually bathes with him.

Riselia and Leonis share the same room, and although at first they agreed that Reselia would sleep in the bed and Leonis on the sofa, she usually drags Leonis to his bed while he sleeps, These actions became so common that currently Leonis and Riselia sleep together in the same bed.

As they spend time together, Riselia has become obsessed with Leonis to the point of not leaving his side unless absolutely necessary, calling him and looking for him as soon as she considers that they have been away for a long time. In the same way, she does not allow the other girls to attend to him, being jealous if Regina or Elfine spend time with Leonis.

As the series progresses and due to Leonis' maturity and composure, Riselia's feelings towards Leonis only grow, she is deeply in love with Leonis (despite not being aware of it yet), and despite pampering him in everything, she is aware (like the rest of the girls) that Leonis is a man in his own right.

Regina Mercedes
Regina is Riselia's personal servant, and apart from being at her service, the two are best friends, supporting each other at all times, the only reason for dispute being who will take care of Leonis, being that Regina is also interested in him.

Elfiné Phillet
Having been personally recruited by Riselia, Elfine has great admiration for her and her willpower, and they usually get along very well.
