Shanoa is one of Ecclesia's female warriors. She joined the clan at a young age and since that point was groomed in her training to destroy Count Dracula. Shanoa was unique amongst her Ecclesia brethren in that she had an innate ability to channel power through "glyphs" (magical energy representative of the power that dwells within all things), as marked on her body, absorbing the spiritual essence of a given specimen. So considerable was this power that Ecclesia founder Barlowe selected Shanoa to receive Dominus, a trio of glyphs representing Dracula, altered to be used as a weapon against him.

Before such a ceremony could commence, there was required a ritual that would mentally prepare her for the harnessing of the nearly uncontrollable power of Dominus. The ritual was interrupted by the enraged Albus, who sought Dominus for himself; this event coincided with a violent severing of the channeling process. Shanoa awakened from the explosive event in an amnesiac state, her memory and emotions wiped away. The scheming Barlowe convinced her that her loss of faculty was due to Albus' ill-intentioned intervention, when in reality Barlowe took advantage of the incident and sacrificed the vulnerable Shanoa's memories and emotions to Dominus for yet-unknown means.

Barlowe then retrained the empty Shanoa and sent her out on a new mission to track down the seemingly corrupt Albus and retrieve Dominus. She managed to locate the increasingly erratic youth on a few occasions, two instances of which saw him inexplicably leave two pieces of Dominus to her care. Things eventually deteriorated to the point where she had to fight her former friend, who was overcome by darkness, in order to kill him and wrest away control of the final piece. Upon doing so, she learned the truth: Albus stole Dominus with the intent to properly control it--to protect Shanoa and find the true means of destroying Dracula, where Barlowe might have had other aspirations. She was told of this, sadly, from the fleeting Albus, who was able to temporarily live on within the Dominus glyph dwelling within her body.

She confronted Barlowe about these matters and learned of his devious plot to actually resurrect Dracula using Dominus. She was forced to fight her former mentor, who before defeat sacrificed himself to ensure the Dark Lord's return. Shanoa, now having nothing left in this world, could only focus on her final mission: To destroy Dracula. Shanoa was able to defeat the Count by unleashing upon him Dominus, the price of which was her life. However, the still-lingering Albus again took her place, sacrificing what was left of his soul to Dominus, asking of the devastated Shanoa one final wish: To see her smile. Though marked by great suffering, it was with much sincerity that she granted this wish.
