Priscilla's datasheet names technique in Yoma War Record I.[5]


Yoma Energy Control enables this technique: attack target by stealth—reduce Yoma energy signature to appear either human or a low-power Yoma entity.

Yoma power usage approximately 0–2%.[6] Yoma power control ranges in the low-80%.[7] Same stats as Yoma Energy Suppression. See Yoma power chart.

Often confused with Rafaela's Yoma Energy Suppression, which suppresses existing Yoma energy. Priscilla's Yoma Energy Control Technique regulates Yoma energy production at source, quantity being adjusted from 0–100%.

Compare Teresa's first reactions to Rafaela[8] with Priscilla.[9]



Marked for death[]

Two warriors—"Storm Wind" Noel (No. 4) and "Muscular" Sophia (No. 3)—meet in a Yoma nest. As they kill Yoma, they argue who should be No. 3. Noel challenges Sophia to a fight.[10]

But No. 2, "Quicksword" Ilena arrives. She says a new No. 2 has been promoted. Everyone has been demoted by one rank. This angers Noel.[11]

The new No. 2, Priscilla, stumbles from alley. Noel challenges her to a fight, then sees alley filled with dead Yoma. Priscilla's Yoma Energy Control enables her to completely turn off Yoma Power. Noel never sensed her fighting in alley.[12]


At another village, the purge team locates Teresa at the local inn.[13]

Teresa repel first attacks of Ilena and Sophia. Then escapes Noel. Despite Teresa's Detailed Yoma Energy Sensing, she does not detect Priscilla's presence, but noticed her shortly afterwards. Priscilla introduces herself.[14]

In the Manga version despite Priscilla's Yoma energy control, Teresa mentioned Priscilla couldn't kill her when she had the chance.

Awakened Being[]


Priscilla, now in guise of young girl, wanders through villages, eating the inhabitants.[15]

Priscilla shows up naked in new village and begins feeding on humans. Rigaldo awakens into the Silver Lion and attacks Priscilla.[16]

From a distance, Isley senses Rigaldo's defeat. Priscilla, in her horned, winged form, stands atop Rigaldo's prostrate body.[17]

Isley awakens into his centaur form. When he fights Priscilla, she destroys half his upper torso.

Neither Isley nor Rigaldo detected Priscilla's true Yoma Power.[18]


Riful first confronts Priscilla in Mucha. After gauging Priscilla's true power, Riful realizes that the story of Isley defeating Priscilla was false. Priscilla is stronger than any Abyssal One.[19]

Riful and Dauf are forced to retreat.[20]

7-year timeskip[]

Renée confronts Raki in village of Doga. She demands to know how he detected the Yoma. When he equivocates, she grabs him by the collar. But a small child intervenes. Renée at first ignores the child, but suddenly retreats.[21]

Raki tries to reassure Renée, who cannot believe he would let the child accompany him. After Renée leaves, Raki pats the head of Priscilla.[22]
