He’s a cult leader. He’s a dreamer. Honestly, he’s probably just a guy who realized early on that sanity is a liability when you're trapped in a parallel-dimension Tokyo where lasers shoot from the sky. If you've watched the Netflix adaptation or read Haro Aso’s original manga, Hatter Alice in Borderland—otherwise known as Takeru Danma—is the kind of character who sticks in your brain long after the credits roll. He isn’t just some eccentric side character; he represents the desperate psychological pivot people make when faced with total existential dread.
Most people look at the Beach and see a drug-fueled delusion. They see a narcissist in a bathrobe. But if you look closer at the mechanics of the Borderland, Hatter was the only one playing the long game with any real strategy.
Who was the real Takeru Danma?
Before he was the "Hatter," he was a host in Shinjuku. That’s a key detail. It wasn't just a random job; it was training for the end of the world. As a host, his entire livelihood depended on his ability to sell a lie so convincingly that people would pay for the privilege of believing it. When he arrived in the Borderland, he didn't just change his clothes; he scaled up his business model.
The Borderland breaks people. It’s designed to. You either die in a game of Hearts because you can’t handle the betrayal, or you wither away as your "visa" expires. Hatter saw this and realized that individuals are weak, but a collective—even one built on a lie—has a chance to survive. He traded his identity as Takeru Danma for a persona. He became a symbol.
He understood something that Arisu and Usagi took much longer to grasp: in a world without rules, the person who creates the rules becomes god. He didn't just want to survive; he wanted to dominate the narrative of the games.
The Beach: A utopia built on a lie
The Beach is often criticized by fans as a detour from the main tension of the series. But that's missing the point. The Beach is the tension. It’s the ultimate social experiment. Hatter’s logic was simple: collect all the playing cards, and someone gets to go back to the real world.
Is that true? We find out later it’s a bit more complicated than that, but in the moment, it didn't matter if it was true. It gave people hope. Hope is a resource. In the Borderland, hope is as valuable as water or food. Without it, you get "dealers" or people who just give up and let the laser hit them.

Hatter established three specific rules that kept the Beach from devolving into immediate chaos. You have to wear swimwear (to prevent hidden weapons), the cards belong to the collective, and death to traitors. It’s brutal. It’s cult-like. But it worked for a surprisingly long time. He managed to organize hundreds of people in a lawless wasteland. That’s not just luck; that’s high-level manipulation and charisma.
The dark side of the Hatter's vision
Power corrupts, sure, but in Hatter's case, it was more like power eroded his grip on reality. He started believing his own hype. The tragedy of the character is that he actually cared about Aguni. Their friendship was the only real thing left in a world of cardboard cutouts and neon lights.
When Hatter started losing it, wanting to kill his best friend to maintain his status, it showed the limit of his philosophy. You can't build a permanent society on a foundation of "Seven of Hearts" trauma. Eventually, the weight of the bodies you've stepped on to stay at the top becomes too much to balance.
Comparing the manga vs. the Netflix series
If you've only seen the show, you're getting a great performance by Nobuaki Kaneko, but the manga dives much deeper into his backstory with Aguni. In the source material, their bond is even more tragic. They were childhood friends. They had a bond that should have survived the Borderland.
In the Netflix version, Hatter feels a bit more like a rockstar. In the manga, he feels like a man who is terrified of being ordinary again. Both versions hit the same thematic beats: the Hatter is the "King" of a deck of cards that is constantly being shuffled. He knew his reign was temporary.
Why does this character matter? Because he's the foil to Arisu. Arisu is the "detective" trying to solve the puzzle. Hatter is the "politician" trying to manage the people trapped inside the puzzle. Arisu wants the truth; Hatter wants a solution that keeps him in charge.
The psychology of the "Seven of Hearts"
We have to talk about the psychological toll. Hatter's descent into madness wasn't just because he liked the power. It was because he was playing the games. He was witnessing the same horrors as everyone else. Every time he went into a game, he risked everything.
The "Seven of Hearts" is the turning point for almost everyone in the series. For Hatter, his "Hearts" game was the Beach itself. He was playing a massive, long-term game of manipulation with hundreds of lives on the line. The stress of that—knowing that if the illusion broke, he’d be torn apart—is what led to his eventual confrontation with Aguni.
He wasn't just "mad." He was hyper-aware. He knew that the moment the Number Ten of Hearts appeared, his little kingdom would burn. And it did.
Was Hatter actually a villain?
It depends on who you ask. To the people at the Beach who got to live another day because of his organization, he was a savior. To the people he "purged" to keep order, he was a monster.
The Borderland doesn't allow for traditional morality. If Hatter hadn't created the Beach, would more people have died? Probably. They would have wandered aimlessly, died in solo games, or killed each other over scraps. He gave them a structure. He gave them a goal.

Even his death served a purpose. It catalyzed the final collapse of the Beach, which forced Arisu to grow up and face the reality of the Face Card games. Hatter was the necessary "Boss" of the first act. He was the obstacle that proved the old world's hierarchies (fame, money, charisma) don't mean anything when you're facing the King of Spades.
Tactical takeaways from Hatter's reign
If you find yourself analyzing the show for leadership lessons—as weird as that sounds—Hatter is a masterclass in "In-Group/Out-Group" dynamics.
- Symbols over substance: The "Beach" name, the uniform (swimsuits), and the hierarchy of "Executives" created an identity. People will do a lot to belong to an elite group.
- The common enemy: He kept focus on the "Game Masters" and the collection of cards. By giving the group an external goal, he minimized internal friction (for a while).
- The cost of transparency: Hatter knew that telling everyone the truth—that they might never go back—would lead to mass suicide. He chose the "noble lie."
What to do next with your Alice in Borderland obsession
If you're looking to go deeper into the lore of the Hatter and the Borderland, don't just stop at the Netflix series. The story has layers that are often missed on a first watch.
- Read the "Alice in Borderland: Road to Borderland" side stories. They flesh out how some of these structures were built before Arisu ever showed up.
- Watch the OVA. There’s an older anime version that captures the "gritty" vibe of the manga in a different way than the high-budget Netflix show.
- Analyze the "Chishiya" connection. Notice how Chishiya treats Hatter. He sees through the bullshit immediately but stays because the structure serves his purposes. Understanding their dynamic explains a lot about how power actually functions at the Beach.
- Re-watch Season 1, Episode 5. Pay close attention to the background characters. You’ll see the seeds of the "Witch Hunt" being sowed long before the game actually starts.
Hatter wasn't just a guy in a crazy hat. He was a man who looked at the apocalypse and decided to throw a party. Whether that makes him a genius or a lunatic is up to you, but in the Borderland, the line between the two is basically non-existent. He played his hand. He lost. But for a few months in a ruined Tokyo, he made everyone believe in magic again. That’s more than most of us could do.
