Konoha: This Zanpakutō Is Too Powerful

Shigure, a genin of Konoha, likes fishing, and his specialty is getting off work on time. No one knows that there is a system hidden inside him that can unlock all Zanpakutō. He himself has no interest in fighting and killing, and just wants to treat the ninja world as a nursing home. However... When he accidentally slashed Zabuza to the point where he doubted his life in order to end the battle early, the system unlocked [Zangetsu]. In order to avoid trouble during the Chunin Exam, he roasted Orochimaru's psychic snake for dinner, and the system unlocked [Ryuen Wakahara]. When Pain attacked, he had no choice but to draw his sword in order to protect the dessert shop he often went to... The entire ninja world saw the roaring ice dragon in the sky. Naruto: "Brother Shigure, how strong are you?" Shigure sighed and sheathed his sword: "I'm just an ordinary person who wants to live a stable life." After saying that, he turned to face the resurrected Uchiha Madara. "Old man, I will only say this once." "You blocked me and went home to eat."
