Darkest Shonen Anime You Shouldn't Let Your Kids Watch

While the shonen demographic of anime is aimed at younger male audiences, fans can name plenty of great shonen titles that stretch the boundary of that audience. For every My Hero Academia or Naruto, there's an even darker and grimmer shonen title, and for that matter, the likes of My Hero Academia and Naruto can get pretty PG-13, too. That's why the parents of young anime fans will want to pick and choose what their children watch and what they don't.

The family can't go wrong with kid-friendly anime such as Doraemon or Kiki's Delivery Service, though kid-oriented anime aren't as popular as the more mature series. So, the parents may end up selecting the relatively tame shonen anime series while saving the more intense anime for later years. There is so much anime out there that no child will feel left out if some shonen anime are declared off-limits for their young eyes.

Fist of the North Star is the Mad Max of Anime

Violent Body Horror Isn't Suitable For Children

Some older anime are fine to show to kids, but others are definitely the wrong pick for family anime night. Fist of the North Star is a hit 1980s anime that's great for nostalgic viewers who want to revisit shonen's simpler days from the era of leather-wearing badasses like Kenshiro. Kids won't get much mileage out of it, though, since Fist of the North Star has so few life lessons to teach.

Like many kid-unfriendly anime series, Fist of the North Star is much too graphic for young audiences. This anime has shocking gore and violence as Kenshiro twists and breaks his many enemies with his pressure point strikes. The famous "You are already dead" scene is an example, with a minor villain getting his head distorted before it flies apart in a shower of gore. If kids want to see martial arts or boxing, Hajime no Ippo or even Yu Yu Hakusho are more ideal.

Chainsaw Man's Bleak Antiheroes and Gore Are For Older Viewers

Kids Won't Relate Much to Denji Anyhow

The 2000s had the famed "shonen big three," while the modern era has its own version in the "dark trio." Perhaps unsurprisingly, none of the dark trio anime are the right fit for children to watch, whether their parents are around or not. Chainsaw Man's graphic violence is too much for kids to watch, with blood and guts positively everywhere.

Even if that's not a dealbreaker, parents may be concerned about how Chainsaw Man lacks any real role models or life lessons for the kids. Family-friendly anime will feature positive lessons about friendship, forgiveness, belief in oneself, and the like. By contrast, the likes of Chainsaw Man will appeal to older viewers who may see themselves in a lost, broken soul like Denji. Or, older viewers may appreciate the subversion in ways young viewers may not fully grasp.

Death Note is Morally Challenging in Kid-Unfriendly Ways

Kids Might Also Make Their Own Killer Notebooks

Unlike some other kid-unfriendly shonen anime, Death Note has minimal violence or gore. There are a few such scenes, such as Light Yagami, the genius antihero, getting shot or people collapsing from heart attacks, but there's much more to consider. Kids probably won't fully appreciate the dark, morally complex themes in Death Note, and it may actually be worse if they do.

That's because there have already been cases of people, including school-aged Death Note viewers, who got into trouble making replica Death Notes. The notebooks may be physically harmless as props, but they are still a worrisome outlet for negative emotions. Revenge or murder fantasies may be expressed in ways no teacher or student would like, so it's best if young viewers aren't exposed to Death Note too soon.

Jujutsu Kaisen Goes Too Hard For Elementary School-Aged Viewers

Demon Slayer is a Safer Alternative

Jujutsu Kaisen is another entry in the dark trio, and like Chainsaw Man, it's too graphic and bloody to be suitable viewing material for the family's young ones. In broad strokes, Jujutsu Kaisen actually does feel like the right kind of great fantasy anime with shonen action, but it's not. Frieren: Beyond Journey's End is OK for children, but Jujutsu Kaisen goes much too hard with its horror and violence for that.

Shocking character deaths and body horror may frighten younger viewers, and even if the kids think they can handle it, parents may feel differently. This is one of the trickier cases for parental discretion, since Jujutsu Kaisen is almost the right kind of action/adventure anime for kids. Meanwhile, Demon Slayer is also somewhat graphic and quite violent, but not in the same horrific ways as Jujutsu Kaisen. It also has more positive themes and narratives overall, where love and hope win over villainy every time.

Hell's Paradise Might Scare Kids With its Body Horror and Nightmarish Visuals

Gabimaru Isn't an Inspiring Protagonist For Young Viewers

Hell's Paradise is the last member of the dark trio, and also seems to be the most underrated of them. Teenage anime fans and older viewers may enjoy what Hell's Paradise has to offer, while parents will steer their kids clear of this one. Hell's Paradise is just as nightmarish as the title suggests, featuring a cast of grim antiheroes who suffer death and injury, along with plenty of terrifying images of dead bodies or body horror.

Hell's Paradise has no protagonist for young viewers to latch onto, no classic good-guy type for kids to learn from. Gabimaru may be relatively noble compared to the other criminals, but not by much, and Yuzuriha isn't an inspiring heroine, either. The realm of fantasy anime has better offerings for the family, from Frieren to Campfire Cooking in Another World With My Absurd Skill.

Attack on Titan is Pretty Unwelcoming For Kids as a Politically Charged Action Anime

Constant Violence and Upheaval Don't Make For a Saturday Morning Cartoon

Any trailer or online discussion for Attack on Titan will make it easy for any parent to determine that this is not the anime for family TV night. Even if parents are pretty new to anime, they will have no doubt that Attack on Titan is wrong for their kids. Once again, savage violence and excessive gore make this a kid-unfriendly anime, and Eren Yeager's descent into villainy doesn't set a good example for the young ones, either.

Aside from that, Attack on Titan's narrative is both too heavy and too bleak for young viewers to properly grasp or enjoy. The plot is already rather tricky for anyone to follow, and kids may feel lost or get impatient with the slow-burning mysteries in Attack on Titan. Above all, this anime's weighty political themes and controversies are not kid-friendly in any sense, with the topic being outside a child's knowledge or comfort zone.
