There are occasional scenes of people being seized by the supernatural or falling presumably to their deaths. One episode features people immobilized by flora that show up as red blemishes or fungi on their legs.

There's one episode with a huge blood spray.

Another episode Ginko gets stabbed with some blood.

Maybe one damn or hell.

Ginko has a habit of smoking

Some (emulation of?) smoking.

Mention of a man committing suicide

Some tragic scenes. The series in general has a cold, sometimes bleak atmosphere, as befitting the main character.
