Sakamoto days characters: who is who, and why they matter

Retired hitman, shop owner

Taro Sakamoto

Sakamoto Mart · former JAA legend

Lead character

The unstoppable lead of Sakamoto Days. Even after leaving the Order to build a family, Sakamoto's instincts, strength, and stealth chops let him neutralize threats in seconds while protecting his store and friends.

A telepathic rookie who balances loyalty with ambition. Shin reads intent to predict moves, and his growth mirrors the series' shift from slapstick to razor-sharp action.

Lu brings chaotic energy and comic relief, but her poison resistance and brute force make her a frontline menace. She anchors the team's chemistry with food, fists, and fearlessness.

Aoi is the reason Sakamoto quit killing. She embodies the slice-of-life warmth that grounds the manga's wild action and keeps the store—and the family—running.

Hana's curiosity and timing add levity between battles. She humanizes the assassins around her, reminding them of the peaceful life they are fighting to protect.

Charming on the surface, lethal underneath. Nagumo's disguises and game-planned traps make him one of the craftiest assassins opposing and aiding Sakamoto depending on the mission.

A deceptively cheerful powerhouse. Osaragi swings a massive hammer with terrifying precision, mixing childlike demeanor with brutal stopping power.

The earnest sniper who idolizes heroes. Heisuke's long-range cover and detailed intel gathering create breathing room for the front line.

Cybernetic limbs and cold logic define Kashima. He builds weapons, enforces Slur's plans, and symbolizes the villain side's relentless innovation.

The shadow pulling strings against the Order. Slur targets systemic rot within the assassin world, forcing Sakamoto and the Order to confront their own history.
