Robertio Iguno Valentia

Robertio Iguno Valentia is a High Priest of the Church of Ente Isla and one of its highest authorities. After the Demon King Satan was defeated by the Hero, Robertio was among the clergy placed in charge of the Inquisition, which the Church used to consolidate power amid the chaos left by the retreating demon army.

Like most of the Church's upper echelons, Father Robertio shows little concern for ordinary people, focused above all on preserving the institution's image rather than any real sense of justice. He helped plan the trials of so-called heretics — the Church's opponents — and despite the resulting deaths, staunchly refuses to accept responsibility for the outcome.

He operated in close coordination with Archbishop Olba Meyer and alongside his colleague Servantes Reberiz, with orders carried out in part by the woman who would later become Maou's neighbor on Earth, Suzuno Kamazuki.
