A 'Perfect' New Anime Has Arrived - But Is It Really That Good?
Each new season of anime always has that one title. The latest anime that came out of nowhere and blew everyone away, instantly hooking countless people with a single episode. Last season, it was May I Ask for One Final Thing? (2025) that took the spotlight. However, while that series was good, the reception to it was not quite as glowing and universal as this season’s breakout hit, Sentenced to Be a Hero (2026).
With only one episode, it earned tens of thousands of five-star reviews on Crunchyroll. Over here on JustWatch, its hour-long premiere rocketed the show as high as #27 on the streaming charts. That’s the kind of reception that most anime can only dream of, but is the series actually good, or is this a case like Solo Leveling (2024), where it’s all hype but no substance?
What Is ‘Sentenced To Be A Hero’ About?
At its core, Sentenced to Be a Hero is a dark fantasy series that, at a quick glance, may seem a lot like Berserk (1997), given its darker tone and penchant for violence. However, it’s not as simple as that.
Our hero, Xylo Forbartz, is quite literally a hero. However, in the world of Sentenced to Be a Hero, that’s the worst thing you can be. Heroes are criminals forced to serve the state as penance for their crimes. Heroes are turned into immortal soldiers and sent on missions to kill demons, but when a hero dies, their soul is ripped from Hell, and they’re reborn in an endless cycle of pain and suffering. Even though they’re literally dying for their country, they receive nothing but scorn and loathing from anyone who sees that they possess the mark of a hero.
Xylo’s crime was to kill a goddess, a biological super weapon meant to eradicate demons, but someone within this world’s theocratic government set him up. Because of that, he swears vengeance and becomes the captain of the hero combat squad known as Penal Hero Unit 9004. There’s plenty of gruesome violence to be sure, and the premiere decides to showcase an armada of demons annihilating thousands of people. Still, the show is closer to 86 (2021) thanks to its morally ambiguous cast of convicts and criminals. This is a war story, and unlike shows that paint a pretty picture, the depiction of the frontlines in Sentenced to Be a Hero is brutal, and the psychological effects of it are clearly debilitating to its cast of indentured soldiers. In other words, this show isn’t for the faint of heart.
Why Are People Calling ‘Sentenced To Be A Hero’ Perfect?
Dark fantasy shows are nothing new. Last year, anime fans were treated to plenty of dark fantasy anime like Clevatess (2025) and Tougen Anki (2025), so what makes Sentenced to Be a Hero so “perfect” after one episode?
A part of that definitely lies in the animation. The series was made by Studio KAI, a relatively new studio that cut its teeth animating later seasons of Umamusume: Pretty Derby (2018). Sentenced to Be a Hero has some incredibly fluid and expressive animation that brings a scale to the conflict that commands your attention. First episodes of action anime tend to try to wow audiences, but Sentenced to Be a Hero takes it to a whole other level. Seeing animals mutate into horrible demons, gigantic cannons launch magical volleys, and an immeasurable amount of swords raining from the sky are all striking images. It’s undeniably a spectacle that will impress anyone who wants big and bombastic action scenes.
Its length is also probably a significant factor, because if the show divided its 58-minute premiere into two or three episodes, it wouldn’t be able to hook viewers quickly. By the end of the premiere, we have a good understanding of what heroes are, what heroes and goddesses are capable of, the corrupt government leading the penal program, and Xylo’s desire for revenge. Like Oshi no Ko’s (2023) premiere, Sentenced to Be a Hero is wholly confident in itself and knows exactly what it wants to be. It doesn’t try to diffuse its grim premise with wacky comedy or shy away from the horrors of war. Sentenced to Be a Hero wants to be a brutal fantasy war epic, and it commits every second of its runtime to proving that.
Is ‘Sentenced To Be A Hero’ Worth The Hype?
While only two episodes of Sentenced to Be a Hero have been released so far of its 12-episode first season, all signs point to the series, at the very least, being one of the best premieres of the Winter season.
The action is stunningly rendered, and it’s not often you see an anime commit so thoroughly to being a dark fantasy epic. It’s undeniably edgy, but not brooding like Tokyo Ghoul (2014). It wonderfully paints a bleak picture of the struggles that Penal Hero Unit 9004 will endure throughout the course of the series and the violence they will encounter. It goes beyond just action, as we get a clear understanding of the emotional toll being a hero will have on them.
Enough plot threads are also teased to give audiences something to latch onto. If you want an intriguing political thriller, Sentenced to Be a Hero teases it. You want character drama, it’s there. If you’re more interested in just a violent spectacle, you’ll also find it here. For once, the hype is real, and Sentenced to Be a Hero is definitely an anime worth watching.
