Visually, Chapter 90 continues the manhwa’s signature blend of gritty realism and stylized surrealism. Backgrounds retain that seeped-ink texture that made earlier action sequences pop, but this chapter favors shadow. A recurring motif—the cracked porcelain doll—returns, reframed not as ominous whimsy but as a ledger of debts. Color is used sparingly but purposefully: a single, saturated red draws the eye to an otherwise monochrome panel, signaling a hook the reader can't ignore.
