10 most stressful anime series of all time

Some of the greatest anime series of all time can be incredibly tense, to the point that just watching them can feel stressful. Jujutsu Kaisen subjects its characters to horrible, painful deaths, while Death Note's villain protagonist uses his intelligence to get away with terrible things.

While these stressful anime series aren't necessarily the best shows for people who want relaxing anime, the life-and-death stakes will get viewers hooked. Even though these anime series have shocking character deaths and brutal moments, they're still incredible to watch.

Kaiji: Ultimate Survivor Is Like a Squid Game Anime

Kaiji: Ultimate Survivor is great fun for fans of series like Squid Game or the anime Kakegurui, though it's slightly less bloody and brutal. Still, even if Kaiji's tone is a tad lighter than Squid Game's, it's a remarkably tense, stressful, and wonderfully suspenseful watch.

This entire franchise is about Kaiji's struggles to win high-stakes games of chance to fight his way out of bottomless debt amid Japan's economic hardship in the 1990s. Kaiji risks life and limb many times in the franchise, and he has nothing but his wits and guts to keep him going when his enemies stack the odds ever higher against him.

Jujutsu Kaisen Keeps Upping the Stakes

Jujutsu Kaisen'sfirst season balances the horror, action, and losses with plenty of humor, but things get much darker by Season 2, when the Shibuya Ward Incident arc begins. The sorcerer heroes barely broke even with the villainous curses, with major characters falling to villains in grim displays.

Somehow, the stakes have only gotten higher as the series has gone on, to the point where Yuji Itadori's voice actor described recording his lines as "the most stressed I've ever been." Jujutsu Kaisen is perfect for fans of dark anime, but it puts its characters through a lot, which is why it isn't easy to watch.

Death Parade Has Gambling With the Highest Stakes

Death Parade may be short, but it packs a lot of drama, suspense, and wild plot twists into that short time frame to keep fans guessing until the very end. The anime's stressful narrative is rooted in how Decim, the bartender, regularly throws his bar's new arrivals into psychologically challenging games, testing those people to reveal their true selves over time.

The people who arrive in Decim's bar aren't always innocent, and they never even know where they are or how they got there. Soon enough, the grim truth will come to light as Decim regularly chooses whether to send his new arrivals either to the afterlife or to a realm of eternal torment.

Terminator Zero Shows Humanity on the Brink of Nuclear Armageddon

The sci-fi anime series Terminator Zero features plenty of violent deaths at the hands of killer robots, just like in the overall Terminator franchise, but that's far from the only source of stress and tension in this anime. The real question is whether Dr. Malcolm Lee can convince his new super-AI, Kokoro, to spare the human race from the destructive fate Skynet had planned for it.

Since Terminator Zero is a fresh new part of the franchise and features characters with limited plot armor, there's no telling what will happen as the robot uprising unfolds in August 1997. Fans will even see Skynet launch its nuclear weapons to begin Judgment Day, all while Dr. Lee pleads with Kokoro to change humanity's fate, and it's suspenseful, to say the least.

Death Note Is a Tense Battle of Wits

The famed crime thriller anime Death Note is a fun yet suspenseful and grim watch thanks to its intense battles of wits and the moral ambiguity of it all. Death Note keeps viewers on the edge of their seats as the genius protagonist Light Yagami risks everything to clash with the super-detective L, and only with his greatest tricks can Light hope to survive as Kira.

Many characters get killed off in Death Note, and that doubles the stress and tension as Light's criminal career continues. There is no telling who might get betrayed or have their name written in a Death Note, leading to some of the best plot twists in all of shonen anime. Even the final episode is a suspenseful affair, with Light facing his bloody endgame as Near's side corners him in a warehouse.

Tokyo Revengers Has Brutal Gang Battles

Tokyo Revengers ranks in the middle among the most stressful, suspenseful, and tension-ridden anime of all because protagonist Takemichi Hanagaki is such an underdog the entire time. This is an anime where almost everything goes wrong, and the hero must fight hard just to stay in the game.

For every one of Takemichi's victories, there is an even bigger defeat, making Takemichi wonder if he's just going in circles. He endures regular beatdowns and tries in vain to change the minds of his fellow delinquents, with each slip-up threatening serious consequences for Takemichi and the people around him.

Fruits Basket Is Much More Stressful Than It Looks

Even romance anime like Fruits Basket can have palpable tension and stress, no matter the happy ending waiting for everyone at the end. In fact, when combined with drama, romance can be one of the most stressful genres of all, with heartfelt personal stakes on the line for all the main characters. However, the cast of Fruits Basket has much more than a potential romance to worry about.

The cursed members of the Sohma family are all dealing with gut-wrenching personal issues concerning their self-worth, verbal abuse, and finding the courage to carve out their own lives despite the risks. Main character Tohrudose her best to heal the Sohmas and empower them to take control of their lives, but it's stressful waiting to see if everyone can break free.

Oshi no Ko Never Lets Up the Tension

The dark idol anime Oshi no Ko combined bizarre plot twists with humor and tragedy just in the first episode, and the stress and tension have only risen since. The main characters all feel serious pressure and stress to find personal happiness while also surviving the exploitative entertainment industry, to the point that the heroes have a hard time telling truth from lies.

For some characters in Oshi no Ko, the stress comes from their efforts to make it big as entertainers. Aqua, meanwhile, is under serious pressure to find his mother's killer at any cost, a grim quest for revenge that is eating him up from the inside. Of course, it's stressful to see Dr. Gorou get a second lease on life as Aqua Hoshino, only to jeopardize it all with his ill-advised mission of vengeance.

Psycho-Pass Is a Dystopian Anime That Can Be Brutal

The dystopian cyberpunk anime Psycho-Pass delves into deeper societal themes than other sci-fi anime like Cyberpunk: Edgerunners usually do. Psycho-Pass will make the viewer feel properly stressed and suspenseful, not about whether protagonist Akane Tsunemori will survive her duties as a futuristic cop, but whether society will ever figure out a way to balance safety with freedom.

Psycho-Pass explores some major themes as it challenges the viewer to wonder how far any state should go to protect its people from violent crime, including the usage of constant surveillance and cops who take down criminals right before they act. In the process, Akane will inch her way to the truth of the Sibyl System and realize who her true enemies are, even if she can't do anything about them.

Attack on Titan Is the Most Stressful Anime Ever

The most delightfully stressful anime of all time is the recent mega-hit Attack on Titan, a breathtaking blend of the zombie genre, mecha, horror, and conspiracies. This is a stressful shonen anime on many levels, starting with the physical level, since no one's survival is guaranteed. Attack on Titan won't hesitate to slaughter its own cast, keeping viewers in a state of constant worry about who will survive.

The mysteries and truth of the Attack on Titan world can also be stressful, since all is not what it seems. Right away, fans will be desperate to know what is beyond the city walls and learn the truth of the destructive Titans. The answers to those questions will actually be more terrifying and stressful than the original mysteries, but they will also lead to some astonishing plot twists, so it's all worth it in the end.
