How can I make a material/postprocessing effect to acheive ink shading like game Okami?

This is rather useless because in actual cellshader/toon ink the dark lines are only visible depending on the angle as well as lighting situations.
Actually adding them into the texture makes it look wrong, fake, and boring.

You do have a point. A shader is needed to get the best outlines. My suggestion is probably not what you were looking for…
