THE STEEL ERA
Kaoru
She smells danger before it has a name. That instinct makes her valuable, and also easy to fool for anyone who knows her patterns.
Behaviour it trains: verifying before trusting your instinct.
MANGA · NOW AVAILABLE ON THE PLATFORM
Three main characters who get it wrong, learn and carry on.
It is original SMARTFENSE content and it comes with interactive activities that make the lesson stick.
Already working with SMARTFENSE? You can find the manga in the content catalog.
THE TRAILER
It all starts with a rift between two worlds that are connected and were never meant to coexist. On the other side are Kaoru, Tatsuo and Yuma, who chapter by chapter teach how to spot real digital risks. Your audience follows them into every battle and learns, panel by panel.
The story is not told on a slide or as traditional training. We tell it in panels, with image and narrative at the same time.
VISUAL STORYTELLING
Whoever reads it is following a story, and comes back for the next chapter for the same reason anyone comes back to a series: to find out how it ends.
INTERACTIVE ACTIVITIES
Every chapter includes exercises that anchor the concepts, the same as the rest of the content on the platform.
A GENRE WITH ITS OWN AUDIENCE
There are over 380,000 monthly searches for “manga online” worldwide.

THE PLAY NEVER GETS OLD
Teaching people to check the sender and the domain stops working the moment the attacker stops making those mistakes. The underlying move, though, has not changed in centuries: someone puts you under pressure, poses as an authority and pushes you to settle it through a channel where you cannot verify anything.
That is why the story happens across two eras.
They are everyday mistakes, the kind people rarely admit out loud. Your audience recognises them, sees itself in them and learns to avoid them.
She smells danger before it has a name. That instinct makes her valuable, and also easy to fool for anyone who knows her patterns.
Behaviour it trains: verifying before trusting your instinct.
A formidable and impulsive warrior. He knows how to fight, but he still has to learn when not to.
Behaviour it trains: stopping before acting.
He freezes when the threat appears, and then KURO-YUMA takes over, the artificial intelligence in his prosthesis, which steps in and resolves things without fear.
Behaviour it trains: not handing all your judgement over to AI.
THE STORY
Kaoru and Tatsuo come from an era of katanas and honour, where an enemy attacks without leaving a trace and yet takes away the essence of people. A rift drags them into the Code Era, into a city that is familiar and unknown at once, where they meet Yuma.
The three of them join a new version of the Brotherhood, one that no longer fights demons with swords but threats that travel through screens, messages and networks.
Attacks that leave no visible wounds and can erase everything a person, or an entire organisation, has built.
THE FORMAT
A manga is read the opposite way round to everything else. You start at the top right panel and move left, both within the page and when moving from one page to the next.
The platform respects that reading direction: the viewer moves forward when you tap the left side of the screen, and it includes a short guide to orient the reader.
Together they make up the broadest offering of Spanish language awareness content on the market.
The content is designed for the way people think and act in Latin America, Spain, Portugal and Italy.
Each catalog is managed independently through a system of roles and permissions.
Wherever you are, you only have to look up to find the tower. Its presence is constant and overwhelming.
That sense gets treated as the magic answer to every information security risk, the one so many people are trying to find.
Best practices to keep in mind when planning campaigns and giving every person a relevant experience.
