Synopsis
Although they stay hidden from the public eye, Witches—individuals with supernatural abilities—have existed throughout human history. Neither especially numerous nor inherently malicious, these Witches can still cause chaos when they misuse their powers for criminal activities. Solving such supernatural crimes is beyond the scope of ordinary law enforcement and is instead managed by the Solomon organization. After completing her training in Italy, Robin Sena is assigned to Solomon's local Japanese branch, STNJ. As a Witch herself with powerful pyrokinetic abilities, she finds herself at odds with STNJ's methods for handling rogue Witches. Specifically, Robin objects to the use of a potion called Orbo, which can weaken or completely neutralize a Witch's powers. To establish her place within the organization, Robin must navigate Solomon's internal politics while dealing with the threat of hostile Witches—both of which pose dangers for entirely different reasons.
