Chapter 1: The Legendary Hit Man

Outside a small neighborhood shop, two boys prod at something on the pavement while a shadowed figure drifts closer. Inside, Taro Sakamoto slurps instant noodles, now a heavyset, mustached family man. A flashback lays out who he once was: a lean, unstoppable killer feared by criminals and idolized by his peers, whose reign ended only after he fell for a convenience store clerk named Aoi, married her, had a daughter, and let himself go soft.

The cloaked newcomer turns out to be Shin, a former colleague who reads minds and once operated as Shin the Clairvoyant. He catches Sakamoto silently imagining lethal ways to handle a rude customer, and earns a palm strike to the face for pointing it out. Shin presses his old idol to return to the trade, insisting a corner store wastes his gifts, but Sakamoto quietly refuses and instead runs errands for the neighborhood, pruning trees and settling squabbles with the same ease he once brought to killing.

Ordered by the organization's boss to eliminate any member who walks away, Shin reluctantly returns to finish the job. Sakamoto turns aside a point-blank bullet using a cough drop and transforms the shop into a battlefield of candy slingshots and hurled snacks before knocking Shin out cold. He wakes upstairs to a warm home-cooked meal with the family, and the kindness of it cracks something open in him.

Shin fails to kill Sakamoto and, moved by the family's warmth, begs the organization's leader to spare him, even offering his own life. Reading the boss's insincere thoughts, Shin instead draws his gun, and a firefight erupts against dozens of hitmen.

Sakamoto arrives armed from a hidden wall of weapons, having planted a microphone on Shin earlier, and rescues him from the swarm. Afterward he hands Shin an apron, and the former assassin takes a job behind the counter, using his mind-reading to help the customers.

The Legendary Hit Man opens both the Sakamoto Days manga and the Amusement Park Arc, running fifty-five pages. It was published on November 21, 2020.
