Anime Review: Sentenced To Be A Hero

The fantasy anime genre is chock full of stories with varied emotional tones. From classic high fantasy like Record of Lodoss War to modern offerings such as Frieren: Beyond Journey’s End, there’s a series to match nearly every mood. There are many great entries, but I’m here to talk about 2026’s Sentenced to Be a Hero. If you’re into beautifully animated heroic action, a penal-pariah protagonist, and visceral grit set in a dark fantasy world where demon lords terrorize the land, this show is for you. 

This anime is an adaptation of the novel series Sentenced to Be a Hero: The Prison Records of Penal Hero Unit 9004 by author Rocket Shokai, an interesting nom de plume. It centers on protagonist Xylo Forbartz, a man whose crimes were so heinous in the eyes of the state that he was sentenced to be a Hero. Ah, but in this dark fantasy, a Hero is not someone who is lauded or welcome in polite society. A Hero is a criminal who has been magically marked to serve out their sentence as a near-immortal and tasked with carrying out the deadliest of jobs. Failure means death. But unlike DC’s Suicide Squad, every time you die, you come back missing a part of yourself. Die enough, and you become a near-mindless husk with almost no sense of self—that is, if you’re even worth bringing back. Many members of Penal Hero Unit 9004 have special powers that make them useful and therefore worth resurrecting. Those who want to remain themselves fight for survival, but those who hold the leash don’t make it easy.

The first episode gives us an hour of action and intrigue, throwing you into the fray like many shows do, but you come out the other side with a solid grasp of what’s going on. As I’ve said before, it’s a trope that’s already been done, but this show does it well. Unlike some of the Western comparables, you’ll end up rooting for Xylo and his crew as the mysteries around his situation and that of his fellow inmates unfold. You’ll learn why he hides behind a jaded shield of sarcasm and brusque manners. Besides, when has a government ever failed to abuse a system that offers it deniability?

The pacing is very good, and despite the flood of despair and drama, the show gives us moments of reprieve through lighter-hearted scenes with Xylo’s other team members and the goddess Teoritta, a biological magic weapon in the form of a precocious little girl created to partner with special combat members of the church. She’s no push over, despite her looks, and she can command a battle when push comes to shove.

Speaking of battles, the action sequences in this show are chef’s-kiss excellent. A lot of care is given to them, with even the background characters not relegated to minimized animations during monster attacks. The monsters are gratuitous and mutated. You won’t find any shortage of monster gore here. The magical energy weapons used by the knights remind me of Skaven warpstone weapons from Warhammer—minus the blowing-up-on-you part. There’s just something striking about bright green energy beams arcing out at foes and burning them to crisps. You’ve also got your standard swords, arrows, and spears that the average soldier and knight use. But where the show really shines is when the Penal Unit characters use their special abilities in combat, as well as goddess Teoritta. I did wonder where Xylo keeps the seemingly endless supply of knives that he uses—kind of like Gambit, with throwing weapons that are energized and explode. 

The folks over at Studio Kai have delivered a great anime this season, which is a feat since they’ve only been around since 2019. It doesn’t hurt that Mushoku Tensei’s director, Hiroyuki Takashima, moved to Studio Kai to direct this show. I have seen complaints that the characters have lacked some shading here and there, especially during action sequences, but for the most part it still looks really good and is easily forgivable. As far as the audio goes, I am happy to report that both the Japanese and English audio are strong, so you can choose your preferred format accordingly. The musical score by Shunsuke Takizawa is pretty good and gets your blood pumping when the action starts, or adds to those tear-jerking moments.

Originally aired January 3, 2026, Sentenced to Be A Hero is definitely one to watch and I can recommend it wholeheartedly. It’s definitely on my list of best anime for 2026. If you want that anime dark fantasy itch scratched you won’t go wrong with this one.

As of the writing of this article, the show is ongoing and can be watched on Crunchyroll with a subscription or whatever platform allows a Crunchyroll addon.
