The design of this Nichirin replica draws directly from Zenitsu Agatsuma's sword as depicted in Kimetsu no Yaiba. The most defining feature - the full-length yellow blade - is faithfully reproduced, along with the tsuba (hand guard) shape and tsuka (handle) proportions that anime viewers will immediately recognize. The hilt wrapping follows the aesthetic detail visible in official character artwork, and the overall blade geometry reflects the katana silhouette associated with Zenitsu's style. While no mass-produced replica can claim 100% screen-accurate tolerances, this piece is designed specifically for display and collector fidelity rather than generic anime merchandise aesthetics.
