In her past life, ugly Mirah was Seraphina's stepping stone; her rescue of Dragon-Blood Archduke Valerius was stolen, and she was silenced. Reborn, she binds a succubus grimoire: by squeezing wealth from arrogant noble males, she buys hair growth, fat loss, and beauty. She uses narcissistic Holy Knight Douglas as a money tool, saves the injured Archduke first, and rises as a vengeful villainess with imperial power.
