One Piece: I am Imu

Dressed in clothing characteristic of the Shinobi World, the hundred-strong expert team immediately ignored existing officials upon entering the capital of the Land of Wind. Splitting into specialized teams, they quickly began their respective tasks:

Those tasked with auditing finances audited finances; those responsible for census-taking promptly started counting the population.

The administrative and social officials quickly acted to calm the anxious populace, immediately opening the granaries to distribute food and water to the entire city.

This naturally displeased the local officials.

But before they could react, they were swiftly arrested by Umigakure shinobi. Most civilians were busy focusing on the distribution of supplies and paid little attention to the fate of these officials, aside from their immediate family members.

However, a group of samurai loyalists drew their swords to defend the arrested officials—only to be swiftly cut down by the Umigakure shinobi like vegetables.

To avoid alarming the civilians outside, the shinobi deliberately refrained from using their newly-issued automatic rifles.

These shinobi had already tasted the sweetness of firearms.

Meanwhile—

The citizens, now supplied with plentiful food and fresh water, immediately felt reassured. They obediently followed all subsequent instructions, no longer discussing matters related to the daimyo.

When officials came to inquire about their household circumstances, they responded politely and happily allowed doctors to examine them.
