Onmyoji and Tengu Eyes Volume 4

Our Hiroshima-based spirit hunting team faces a ghostly grudge more vicious than ever before...
When the Abnormal Disaster Unit receives a call for backup from a neighboring town, they send Misato, Ryouji, and Hirose as a party of three to respond. The overview of the case is simple: A haunted kagura mask has disappeared. To deduce the mystery, they turn to Yukiko—a college student researching Hiroshima-style kagura dance. However, when a suspicious man wearing the missing mask attacks Yukiko’s father, the police get involved. Thus begins a chaotic whirlwind of incidents, all leading back to the kagura mask’s influence. The mask slowly sneaks up on them, whispering sweet promises…
“Then, why should thou not hope to become a demon?”
This volume also includes “The Flower Thief’s Favor,” a prequel set amid the fluttering sakura petals of spring.
