In a world where spirits walk among humans, their presence is a fact of life-and death. Most people can see them. The strongest can fight them. But only one person is completely blind to them.
Ryo Kisaragi was born without the ability to see spirits, a flaw that should have made him powerless. Yet, when an unseen force devours his city, he survives what no one else could. The Sentinels-one of many exorcist factions-take him in, but their interest isn't out of kindness. To them, Ryo is an anomaly. A mistake. A threat.
Thrust into a brutal war between spirit-hunting factions and entities far beyond human comprehension.
