Science fiction has stood as a cornerstone of the anime medium since its earliest days. From foundational pioneers like Astro Boy and Space Battleship Yamato to the diverse, multifaceted modern hits of today, sci-fi continues to push creative boundaries and captivate audiences with breathtaking storytelling.
What draws fans to the genre is its endless capacity for futuristic speculation, blending technological marvels with thought-provoking commentary and cautionary tales. The 2020s have proven to be a golden era for the genre, highlighted by several standout series that define contemporary sci-fi anime.
Heavenly Delusion Fully Engrosses Viewers in Its Mysterious Dystopian Setting
Released in 2023, Heavenly Delusion is an unconventional adventure that weaves two parallel narratives. The first follows Maru and Kiruko as they navigate a desolate, monster-infested Japan in search of a sanctuary known simply as Heaven.
Meanwhile, the second storyline centers on an isolated, high-tech sanctuary where children with extraordinary abilities are raised, though supervisors treat the outside world as a forbidden hellscape. Uncovering how these two plots intersect forms the core appeal of the series, drawing viewers deep into its haunting and intricate universe.
Boasting high production values and an instantly gripping premise, Heavenly Delusion leans into a dark, gritty tone. It expertly balances pulse-pounding action with psychological dread, unafraid to tackle heavy, unsettling subjects that keep audiences on edge.
Though its initial season leaves many questions unanswered, it serves as a brilliant showcase for its world and characters. Heavenly Delusion offers a remarkably fresh take on post-apocalyptic science fiction, making it a hidden gem well worth discovering.
Takopi’s Original Sin Uses a Gimmicky Sci-Fi Premise to Tell a Deeply Human, Grounded Story
At first glance, Takopi’s Original Sin looks bright and charming. It introduces an octopus-like alien named Takopi who visits Earth with a simple objective: to spread joy. His first human acquaintance is a lonely, bullied nine-year-old girl named Shizuka, whose grief proves far too heavy for the optimistic alien to easily fix.
As Shizuka’s grim reality fails to improve under Takopi’s naive guidance, the story takes a sharp, shocking turn at the end of the premiere episode. What follows is a heartbreaking time-travel narrative that starkly illustrates how good intentions can lead down a devastating path.
Despite its sci-fi trappings, the true power of Takopi’s Original Sin lies in its unflinching human drama. It addresses brutal themes like child neglect, cycles of abuse, and peer cruelty with raw honesty. While an emotionally heavy watch, its depth is deeply rewarding.
Fitting its concise six-episode run, the series wastes zero time. Every single moment is purposeful, delivering a complete, impactful emotional journey without a single dull stretch.
86 Is the Best Example of a Modern Mecha Anime
While the mecha subgenre once dominated the industry decades ago, today’s landscape sees fewer entries of its kind. Released in 2021, 86 stands out as a rare mecha masterpiece that proves the subgenre is still capable of greatness.
The story takes place amid a brutal, decade-long war between the Republic of San Magnolia and the Empire of Giad. Citizens of San Magnolia believe their side fights bloodlessly using autonomous drones, but the grim truth is that these machines are piloted by marginalized humans forced to fight from the segregated 86th District.
Beyond its high-octane mecha combat, 86 functions as a powerful anti-war narrative. It explores systemic prejudice, survivor’s guilt, and the devastating toll of conflict on both combatants and society at large.
Rooted in grounded character development rather than mere spectacle, 86 echoes the thematic depth of classic mecha anime while carving out its own place as a modern classic.
Pluto Feels Like a Throwback to the Roots of Sci-Fi Anime
Netflix’s 2023 miniseries Pluto stands tall among the decade’s best sci-fi offerings. Its foundations trace back even further, stemming from Naoki Urasawa’s acclaimed manga adaptation of a timeless manga icon, Astro Boy.
Enhanced by state-of-the-art animation, Pluto retains a classic, nostalgic feel concerning the relationship between humans and androids. It unfolds as a patient, atmospheric noir mystery, following a robot detective named Gesicht as he investigates a string of murders targeting advanced robots and human advocates.
Rather than relying on rapid-fire action or cheap plot twists, Pluto commands attention through intelligent writing, careful pacing, and strong direction. Its detective framework provides the ideal lens for examining philosophical themes like the definition of humanity, the emotional weight of artificial intelligence, and the true cost of war. Such thoughtful anime projects are rare and leave a lasting impression.
Cyberpunk: Edgerunners Is a Vibrant Sci-Fi Masterpiece With a Tragic Core
The 2022 miniseries Cyberpunk: Edgerunners ranks among the decade’s biggest sci-fi hits, even revitalizing interest in the video game source material, Cyberpunk 2077. Studio Trigger packed an extraordinary amount of style, kinetic energy, and raw emotion into its compact runtime.
The narrative follows David Martinez, a struggling student at Arasaka Academy who, following a devastating personal tragedy, dives into the criminal underworld as an edgerunner. Night City is portrayed as a hypnotic yet terrifying tech-noir dystopia that easily pulls viewers into its neon-lit chaos.
True to Studio Trigger’s signature style, the action is blisteringly fast and visually explosive. Yet, beneath the chaotic violence lies a deeply poignant story centered on sacrifice and the tragic pursuit of ambition.
Balancing breakneck pacing with profound emotional weight, Cyberpunk: Edgerunners resonates deeply with audiences, leaving fans eager for future stories set within the universe.
