Ceraphina

Ceraphina is an angel who makes her first appearance in Euryale's Gambit. Being made aware of Euryale's activities by dead souls trying to get into heaven and by the prayers of Samuel, she sets a trap for Euryale to try and stop her from entering what she believes to be a holy cathedral.

Background
After the fall of the olympians, angels started to die off after engagements with demons and humans. Ceraphina was part of a group of angels who had refused any engagements after the fall. Although Ceraphina had never fought against demons directly, she trained hard and became very strong.

Over time, Ceraphina became discontented with the apathy that her brothers and sisters had towards the plights of humans. Futher, she longed to discover the whereabouts of her mother, a goddess, who fled into the mortal plane not long after Ceraphina was born. She desired to search her mother out in the mortal plane but no one in her group would support her. After several dead mortal souls lobbied entry into heaven and reported that Euryale, who the described as a demon, had been going on a killing rampage Ceraphina decided to act. She had heard the prayers of Samuel and decided to set a trap around the Cathedral where Euryale was to return. Euryale triggers the trap and Ceraphina engages Euryale in combat. Euryale seduces Ceraphina to the point where she collapses. Euryale then tries to "bind" Ceraphina to her and Ceraphina passes out in the process. She regains consciousness some time later and finds Euryale in the Cathedral being held against her will by a succubus queen named Igret. Seeing Euryale's pain at the revelation of her sister, Ceraphina has a strong desire to help Euryale. She offers her assistance in helping Euryale with her mission and to help her discover the truth about who she is.

Companionship with Euryale
Over time it becomes clear that Ceraphina has become bonded to Euryale and remains a loyal companion and lover to Euryale throughout her adventure in Euryale's Gambit.
