Haruto

Lore & Background

Before Sakamoto hung up his gear and traded bloodstained tactical gear for a name-tagged apron, he led a small, elite team that dominated the professional assassin rankings. Haruto was one of the trusted operatives who worked alongside him during that era, sharing missions, debriefs, and the quiet camaraderie of people who have seen the worst of each other and stayed anyway. The team's disbandment—triggered by the events that forced Sakamoto into his retirement—scattered its members across the underground, each finding their own path forward.

In the present-day story, Haruto re-enters the frame as the assassination world begins to close in on Sakamoto's quiet life. His knowledge of old protocols, enemy networks, and the unspoken rules of the trade makes him a valuable resource for the convenience store crew, even if his first instinct is still to solve problems the way the old team used to: fast, loud, and with very little regard for property damage. His dynamic with Gaku is particularly endearing, as the boy's earnest, rule-following nature clashes hilariously with Haruto's battle-worn pragmatism.

What makes Haruto resonate with readers is the way he embodies the cost of the old life. He is not bitter, but he carries the weight of years spent in a world where trust is a liability and every handshake could be a setup. His loyalty to Sakamoto is not blind; it is the loyalty of someone who chose to stand beside his leader through the worst days and chose again when the world expected them to drift apart.

In Their Own Story

The convenience store's fluorescent lights buzz at 2 a.m. when the bell above the door chimes. Haruto steps in, still in his jacket, rain dripping from the hem onto the checkered floor. He doesn't look at the shelves. He looks at Sakamoto, who is stacking canned coffee with the mechanical patience of a man who has long since stopped being the #1 assassin.

"They're moving the Kuroda file," Haruto says. No preamble. No greeting. Just the words, flat and final, like a blade laid on a counter.

Gaku, perched on a stool behind the register, looks up. "The… file?"

Haruto's jaw tightens. He glances at the boy, then back at Sakamoto. For a moment the old team is back in the room, compressed into the narrow space between the rice-ball case and the magazine rack. Then Sakamoto sets down a can of black coffee, wipes his hands on his apron, and says, "Close the register, kid."

The bell chimes again as Haruto pulls a chair from the back room and sits. Outside, the rain keeps falling. Inside, three men who once broke the world's most dangerous rankings sit in the blue glow of a 24-hour store, and the old war starts, quietly, over a pot of cheap coffee.

Reader's Guide

Haruto enters the story as a former operative on Sakamoto's original #1 assassin team, surfacing in the early chapters as the team's history is pieced together. His role is that of the loyal, battle-hardened colleague who represents the operational muscle and tactical memory of the old group.

Personality-wise, Haruto is blunt, protective, and deeply practical. He speaks in short sentences, acts before he explains, and has zero patience for civilians who don't understand the rules of the underground. Around Gaku, however, his edges soften into a gruff, almost paternal warmth that the boy's innocence draws out.

In combat, he favors direct, overwhelming force—closing distance quickly and ending engagements with minimal wasted movement. He is less flashy than Sakamoto's legendary improvisations but more reliable in a sustained fight.

His key relationships are with Sakamoto (a bond forged in years of shared danger), Kuroda (a complicated former teammate dynamic), and Gaku (the unexpected soft spot). Narratively, he serves as the bridge between the past and present: his knowledge of enemy networks and old protocols becomes critical as the assassination world reasserts itself around the convenience store.

The series balances his presence with both comedic domestic beats—awkward interactions with store customers, Gaku's innocent questions cutting through his stoicism—and high-stakes action sequences where his old instincts kick in and the convenience store becomes a battlefield.

Did You Know?

• Haruto's bond with Sakamoto was forged years before the story's present day, during the team's peak as the #1 ranked assassin group in the underground.
• His interactions with Gaku often highlight the generational gap between the old assassin world and the civilian life Sakamoto is trying to build.
• Haruto's tactical knowledge of the underground's networks and protocols becomes a critical resource for the convenience store crew when old enemies resurface.
• Despite his combat background, his most memorable moments in the story are often quiet ones—sharing a meal, watching Gaku study, or standing guard outside the store in the rain.
