First Appearance: Volume 1
A 12th grade student and the prettiest girl in the academy. Comes from
the old noble of pure devils, the house of Gremory, a top-class devil
who is called a genius nicknamed "Crimson Ruin Princess". Her brother is
in fact one of the Yondai-Maou, Lucifer. Both of them possess the power
of destruction. She revives Issei as her servant after finding him
dead, killed by a fallen-angel and possessing a rare Sacred Gear.
From her mother, Rias has inherited the Bael Clan's Power of
Destruction. This power allows her to release energies that can
disintegrate matter, both living and inanimate, with relative ease.
Opponents who wield sufficiently greater power, however, can shield
themselves from this.
Rias
has gained the ability to project a red light from her breasts, which
recharges Issei's energy. Each use of this power causes her breasts to
temporarily shrink in size, which makes Issei cry even though it's
sometimes necessary. Her breast size will restore itself after a few
days of rest.
Rias has a
lot of affection towards Issei from the start of the series, which
seemed to have grown as the series progressed. This is highly attributed
to the Gremory's tendency to have close relations with their servants
as compared to other clans. Rias doesn't seem to mind allowing Issei to
gaze on her naked body. Following the events of Volume 2, Rias falls
madly in love with Issei and attempts to keep him away from the other
girls who may have affections for him. This includes, but is not limited
to, Akeno, Asia, Xenovia, Koneko, Irina, and Ravel.
She loves him very much and is willing to do anything with and for him.
In response, Issei will do anything to protect her, as he loves her just
as much as she loves him. After being Issei's girlfriend, Rias begins
to show more confidence in her relationship with Issei, no longer being
easily jealous or angered by Issei being close to other girls like she
previously does, even accepting Issei's dream of having a harem. She was
completely heartbroken by the news of Issei's death and locked herself
in her room, crying (which Sairaorg berates her for), but gained a great
deal of hope when she found out that his spirit was still alive through
his Evil Pieces. Despite hating being called the Switch Princess, Rias
seems to only enjoy the title when she gives energy to Issei.
