The threat of evil spreads as Lord Shinzen falls further under the spell of the wizard Azuma, whose true allegiance lies with the demon Taku. Shinzen makes a shocking sacrifice to the powerful Demon which completes his decent into madness. Ashigura’s victory over Shinzen’s army is short lived as the demon Taku unleashes his undead minions on the Samurai’s unsuspecting army.

Meanwhile Ishida returns home to a less than warm welcome. His brother’s most loyal retainer, Koshiro, has no love for monks and their way of life. Soon both men’s beliefs will be tested as they face a force that threatens to destroy not only Japan but all of humanity.
