๐I'll recommend you a few novels with a zankita in Naruto, including Trash Skills Becoming the Strongest Ninja, Naruto's Strongest Escaping, Records of Divine Power, Naruto's Strongest Ninja, The Great Sword Hero of Koba, Death: Starting from the Rule of the Virtual Circle, 777 Times Power Enhancement Starting from Koba, My Sister is Unrivaled, Death's Ultimate Enhancement, and Koba Dancing on the Zankita. These novels all used the katana as the main weapon and traveled to the Naruto world as the main plot. I hope you like my recommendation.๐
