"In volume 2 of the Feudal Japan series
Tamahagane, the kunoichi Otomi seduces Hayato and puts him to sleep with a poison kiss before being attacked by the heroine Kasumi. Otomi handily strangles the girl with a chain, but she's interrupted by a summoned crane that bursts into the room and her naked body is
brutally pecked to a pulp. After a view of Otomi's bloody corpse, which had an arm torn off and has an
anguished expression on her face, the next page
jarringly cuts to a close-up of her large bare breasts in Hayato's dreams."
