The peace is suddenly broken when warning sirens blare through the Soul Society. Residents are disappearing without a trace and nobody knows who's behind it. Meanwhile, a darkness is approaching Ichigo and his friends in Karakura Town.

A team of assassins exacts a bloody retribution on Joe Logan – a former ninja who escaped his clan – and his family for betraying their ancient code. Rising from his seeming "death," Joe will re-emerge as his former self – Ninja Kamui – to avenge his family and friends and bring down the very clan that made him.
