The story of the characters of In the Walnut is actually a spin off a oneshot that was published in volume 2.

What do a gallery owner, Hideo Tanizaki, and a young, naïve filmmaker, Sohei Nakai, have in common? Well, both of them are 24 years old – that’s a good start. They both graduated from the same art school – that can’t hurt either. The fact that Tanizaki has a penchant for art forgery is just one “minor” difference between the two that Tanizaki hopes to rectify pretty quickly.
