Sakamoto Days: Every Member Of The Order, Ranked
From Sakamoto to Kamihate, here are the rankings of all of the members of the Order.
7The Perfectly Balanced Protagonist
Deadly Skills in an Unlikely Package
At first glance, Taro Sakamoto appears to benothing more thana friendly neighborhood convenience store owner with a dad bod. This visual contradiction is thebrilliant core conceptof the entire series:a legendary assassinwhose current appearance completely belies his capabilities.
What makes Sakamoto a good protagonist isn’t just this juxtaposition but how he embraces both sides of his identity. Hegenuinely loveshis peaceful family life and takes pride in his store, while still maintaining the sharp instincts and incredible skills that made him a legend.

When danger threatens his new life, the transition frommild-mannered shopkeeperto an unstoppable tank happens in an instant, often to hilarious effect.
The series consistently finds creative ways to incorporate Sakamoto’s weight into fight scenes rather than treating it as a hindrance, showing him using momentum and mass to his advantage. This approach turns what could have been aone-note jokeinto an integral part of his fighting style, making every action sequence both thrilling and uniquely Sakamoto.

6Action Sequences That Redefine “Creative”
Convenience Store Combat at Its Finest
The action in Sakamoto Days demonstrates an exceptional mastery of visual storytelling. Fight scenes aren’t just well-drawn, butingeniously conceived, with everyday objects and environments transformed into deadly weapons and battlegrounds.
It’s amazing how the series uses Sakamoto’s surroundings. A convenience store becomes a tactical playground, withshelving units providing cover, products becoming improvised weapons, and tight aisles creating unique combat challenges. This environmental awareness extends to every location, making each battle feel distinct and taking full advantage of thesetting’s possibilities.

Most impressive is how clearly choreographed these complex sequences are. Even when multiple characters are involved infast-paced combat, the action remains easy to follow while still delivering surprising moments that showcase incredible creativity.
5The Perfect Supporting Cast
Each Character Brings Something Unique
While Sakamoto himself would be enough to carry the series, the supporting cast elevates it to another level. Each character is thoughtfully designed tocomplement Sakamoto’s abilitieswhile having distinct personalities and skills that make them valuable additions to the story.
Shin, the mind-reading former assassin, provides both comic relief and tactical advantages with his ability. Hismore emotional, expressive naturecreates a perfect foil for Sakamoto’s deadpan reactions. Similarly, Mashimo is an ace sniper capable of filling Sakamoto’s range disadvantage. A recon drone, and a sniper, what else does a frontliner need to wreak up a storm?

What makes these relationships work so well is the genuine bond that forms between them. Despite their deadly backgrounds, there’s an underlying warmth to their interactions, whether they’redefending the storefrom assassins or just handling the daily business of running a convenience store.
4The Perfect Balance of Comedy and Action
Ingenius Transitions Between Laughs and Thrills
Few anime manage to be genuinely funny while maintaining high-stakes action, but Sakamoto Days excels at this difficult balance. The comedy neverundermines the tension of dangerous situations, while the action never gets so dark that it loses the series' inherent charm.
Much of the humor comes from theincongruity of Sakamoto’s two worlds colliding: The domestic family man facing off against the violent underworld he left behind.
A typical chapter might include Sakamoto worrying about a sale on perishable items while simultaneously neutralizingmultiple assassins, with neither element feeling out of place.
The series also excels at visual comedy, with expressive character reactions and perfect timing in panel-to-panel transitions. The humor feels organicrather than forced, arising naturally from character personalities and situations rather than relying on generic anime comedy tropes.
3Masterful World-Building
A Rich Assassin Underworld
Beyond its central premise, Sakamoto Days gradually reveals a fascinating world of assassins with its own rules, organizations, and hierarchies. Rather than dumping exposition, the seriesreveals itsworld-building organicallythrough encounterswith various assassination groups and individuals from Sakamoto’s past.
TheJAA (Japan Assassin Association), the Order, and other organizationsare introduced as the story progresses, each with distinct approaches and ideologies regarding the assassination business. This creates a background against which the main story unfolds, providing context for the constant threats arriving at Sakamoto’s doorstep.
The assassination world operates just beneath thesurface of everyday Japan, with most civilians completely unaware of the deadly professionals walking among them, including the one selling them snacks and cigarettes.
2Escalating Stakes That Never Lose the Plot
Growing Threats Without Growing Pains
As Sakamoto Days progresses, the threats and challenges naturally escalate, but the series never loses sight of its central premise and appeal. Unlike many anime that start strong but drift from their original concept, Sakamoto Daysmaintains its identitywhile expanding its scope.
Each new arc introduces more powerful enemies and higher stakes, but these escalations feel natural rather than forced. The series creates genuine tension about whetherSakamoto can continue to protect his normal lifeas more dangerous elements of his past emerge, maintaining the essential conflict at the heart of the story.
Most impressively, Sakamoto Days continues to find new ways to challenge Sakamoto that go beyond simply making enemies stronger.
