Reiko Natsume

As the maternal grandmother of Takashi Natsume, this powerful medium is the source of his immense spiritual lineage. Though she once used the Book of Friends to command various youkai as servants, her aggressive, bullying nature led to deep isolation from both humans and spirits. Despite occasional acts of hidden kindness toward humans, she remained largely despised by the world, leaving behind a complex legacy of both loyal followers and bitter enemies.
