Master the corrupted, jagged forms of Thunder Breathing with this premium 104cm Kaigaku replica Nichirin katana from Demon Slayer: Kimetsu no Yaiba. Beautifully crafted to achieve a true-to-anime life scale, this iconic weapon flawlessly materializes the striking look of Zenitsu's rival-turned-demon into a format built perfectly for elite collectors and cosplayers alike.

Spanning an authentic total length of 104cm, the sword arrives fully assembled and structurally optimized for immediate showcase. The hilt (tsuka) features a traditional dark brown diamond-pattern grip wrap set over a bold yellow underlay, culminating in a matching gold-capped pommel. Sitting at the base of the blade is Kaigaku's classic clover-style handguard (tsuba), beautifully rendered in a layered golden tone with a clean white collar accent. The unsharpened safety blade itself boasts an exquisite custom finish—featuring a polished silver core beautifully offset by a striking, jagged black lightning bolt streak running along a vibrant yellow blade face. Complete with a sleek, high-gloss black protective scabbard (saya) accented by a matching golden metal tip collar, this masterpiece anchors your setup with pure Shonen brilliance.
