D.Gray-man: The Emergency of the Generals, Vol. 4

The illustrations really emphasize the horror elements but also keep the story moving. I wonder what influenced the pacing of the visual storytelling.

The characters face some tough decisions that blur the line between right and wrong. Did these moments challenge anyone else's sympathies?

The character designs are so distinctive and memorable. I'm curious whether the artist drew inspiration from folklore, mythology, or other sources.
