Tsuchimikado Natsume, the main girl protagonist, is captured when a bad guy uses an Ofuda scroll to render her unconscious. The final spread of volume 2 is an amazing shot of the girl unconscious on the ground.
The scene continues into volume 3, where we get a color splash page showing the girl in some bondage. She wakes up with her hands and feet bound with rope.
Her boyfriend ends up rescuing her.
Overall great scene.
