Japan is in the Age of Warring Provinces. Everyone fights everyone else; forts and monasteries burn; crows feast on the battlefields. The warrior monk Kanyō, abbot of the Hongan-ji monastery, can no longer bear this horror. He asks the Buddha Amida to do something that would put an end to the bloodshed—and the merciful Buddha comes to the monk. The gift of Buddha will change the entire further history of the surrounding lands, turning the Land of the Rising Sun into the Pure Land.
Soon, the government of the Pure Land establishes the Karp-and-Dragon service, whose duties will include investigations of special cases connected with the gift of the Buddha. And a hundred years after Kanyō’s prayers, the grandmother of a young samurai from Akiyama will die. Her death will be the beginning of astonishing events worthy of being archived in an official record.
