She, along with her sisters, are new vassals of "Amon", who was transformed into the "Demon Deity" by the power of "Void". They are siblings of succubi, who always work together. Born in the family of high-ranked succubi, they can sink into the consciousness and show hallucinations without using dreams as the media. "Draw", the wise eldest sister, and "Deal", the silent middle sister, have already mastered this psychic power. However, the psychic power of "Trick", the innocent youngest sister, has not appeared yet, due to her young age.
Desiring a powerful psychic who can interfere with the mind, "Amon" aimed at vassalizing "Draw", and it turned out that all three succubi were vassalised accidentally. Only "Draw" is aware of the fact that they are vassalized. However, she does not tell her sisters the truth deliberately, because she doesn't want her weaker sisters to fall in fear. Of course, she knows how reckless oppossing the Marquis is, since the Marquis has gained the power of another planet and become a powerful being. To save her younger sisters before exhausted as pieces of chess, a bird of prey hides her sharp eyes with her beautiful limbs. Pretending to be pathetic servants who succumbed to an enormous power, "Draw" is waiting for an opportunity to turn the tide.
The Vassals are…
The general name for those whose bodies are engraved with the insignia of high ranked demons. A portion of demons with strong power can convert others to their sides forcefully. This is done by a ritual, of which the demons use their blood and flesh as a medium to engrave its insignia into the victims. Those whose power and/or mind are weak cannot even notice that they have become the targets of such ritual. To undo vassalisation, the victims have only two choices, “to gain stronger willpower” or “to exceed their lords in term of power”.
