Top 20 Darkest Fantasy Anime

Fantasy worlds can be bright and exciting, or dark and dangerous. Dark fantasy anime combines magic with real threats, and doesn’t follow traditional fairy tale rules. These shows and movies often feature curses, demons, and crumbling societies to explore themes of survival, the pursuit of power, and the difficult consequences of decisions. They force characters to face impossible situations where every option leads to pain.

This list features shows and movies that explore dark and unsettling themes, including dangerous creatures, oppressive societies, and ancient secrets. You’ll discover stories set in haunted places, revolving around hidden cults, tyrannical rulers, and bizarre, otherworldly mysteries. Each description includes details about the story, where it takes place, and how intense it is, so you can choose something that matches your current mood and how much darkness you’re in the mood for.

‘Berserk’ (1997–1998)

The story centers on Guts, who becomes a member of Griffith’s Band of the Hawk and battles in a war that dramatically changes the kingdom. The anime focuses on the Golden Age storyline, gradually showing how the characters become marked with a destiny that connects them to powerful, otherworldly beings.

This adaptation of the story features intense medieval combat, cunning political strategies, and a dramatic turn from realistic warfare into a world-altering, fantastical event. It emphasizes how actions lead to results, and builds the foundation for a much larger story that will continue in future projects and the original manga.

‘Attack on Titan’ (2013–2023)

For generations, humans have lived in fear behind massive walls, protecting themselves from gigantic creatures called Titans who roam the land and eat people. When Eren Yeager joins the military with his friends Mikasa and Armin, they begin to discover the shocking secrets behind the Titans and the world that lies beyond their walled city.

Over the course of the show, the story grows from a fight for survival within one city to a much larger war across an entire continent. It blends elements of military tactics, hidden family histories, and characters changing in unexpected ways, all while the world expands from a few neighborhoods to include faraway lands.

‘Made in Abyss’ (2017– )

Riko and the robot Reg venture into the mysterious Abyss, searching for Riko’s mother. As they descend, they encounter strange relics and creatures, each governed by its own unique rules. The further they go, the more dangerous the curse becomes for anyone trying to climb back up.

As a fan, what really grabbed me about this world is how clearly defined everything is – the different layers feel like totally separate places, each with its own dangers, especially when you climb higher. I’m really excited to see the movies and next season because it looks like they’re going to show how everyone – explorers, groups, and anyone after the cool stuff down there – are all fighting for control of the Abyss. It’s going to be a real struggle for dominance!

‘Devilman Crybaby’ (2018)

Okay, so things went crazy after my friend Ryo dropped this bombshell about a secret war between humans and these…monster things. Then, Akira actually *merged* with one of them! It’s total chaos now – everyone’s freaking out, society is falling apart, and honestly, it’s getting hard to tell who’s a human and who isn’t anymore. It’s really unsettling.

This adaptation of the manga is a fast-paced, complete story, taking viewers from individual discoveries to worldwide disaster. It features striking physical changes, strong religious themes, and a satisfying conclusion that ties up all the main plot points.

‘Claymore’ (2007)

Claymores, warriors who are half-human, track and fight shape-shifting monsters called Yoma in a medieval world. Clare is on the hunt for a particularly strong enemy while also navigating the complexities of the organization that made her what she is.

The series establishes a defined power hierarchy, highlights the dangers of using abilities, and sets limits on how quickly characters can heal – all of which are important during fights. It closely follows the original manga for most of its run and delivers a conclusive anime finale that differs from what happened in later chapters of the printed version.

‘Hellsing Ultimate’ (2006–2012)

Hellsing Organization employs the powerful vampire Alucard to protect Britain from supernatural undead dangers and a rising enemy connected to secret experiments from the war. Integra Hellsing leads the operations, and Seras Victoria quickly becomes a vital member of the team.

This animated series closely adapts the original manga, telling a complete story of clashing groups, hidden technology, and large-scale conflicts that engulf the city. With episodes longer than usual TV shows, the major fights and mysteries are fully developed and shown.

‘Dororo’ (2019)

A powerful samurai lord made a terrible deal: he promised parts of his newborn son’s body to demons in exchange for strength. Miraculously, the boy, named Hyakkimaru, survives. He journeys with a young thief named Dororo, and together they seek to defeat the individuals bound by the original demonic pact and reclaim Hyakkimaru’s stolen body parts.

Every episode highlights a different area plagued by demons, while also developing the complex political relationships surrounding the main character’s family. The series concludes the story by showing both the healing of the land and the consequences for the villages caught between powerful nobles and dangerous creatures.

‘Parasyte -the maxim-‘ (2014–2015)

When alien parasites invade Earth, they begin taking over human bodies. Shinichi is lucky – the parasite only partially infects him, resulting in an intelligent creature living in his right hand. However, not all parasites are so restrained, and many take a much more aggressive approach.

The series follows characters as they juggle school and investigate the fascinating world of parasites – how they live and interact with each other. As the story unfolds, the government’s involvement grows, leading to increasingly intense operations that challenge the central characters’ fragile alliance.

‘The Promised Neverland’ (2019–2021)

A group of children, secretly raised in isolation, uncover the truth about why they were brought together and begin plotting their freedom. Emma, Norman, and Ray work together, carefully planning and strategizing while trying to stay hidden from the woman in charge and the people she caters to.

As a huge fan, I thought the first season really took its time with the initial escape storyline, which I appreciated. It carefully laid out how the surveillance system worked, how they tracked the characters, and the pressure of those ticking deadlines. Then, the show moved into later parts of the story at a quicker speed, and finally showed us everything happening outside of that central location – giving us a really complete picture of the world they inhabit.

‘Dorohedoro’ (2020)

Caiman, a man with a reptile’s head and no memory of his past, lives in a city controlled by powerful sorcerers. Alongside Nikaido, he searches for the wizard who transformed him, all while various magical groups pursue their own hidden agendas.

The story takes place in two very different worlds: a poor, rundown slum called Hole, and a magical realm inhabited by sorcerers with their own unique traditions and cuisine. The current storyline focuses on seasonal events like alliances, curses, and competitions, and sets the stage for future story arcs from the original manga.

Young girls are tempted with the chance to gain power, but this comes at a hidden and permanent price. Madoka and Homura find themselves trapped in a repeating pattern where getting what they wish for ultimately leads to sadness and hopelessness.

The show establishes specific rules for how deals, magic, and time travel work, and demonstrates how each wish alters those rules. The sequel movie builds on this foundation, adding new rules and expanding on the implications of the first story’s conclusion.

‘Goblin Slayer’ (2018– )

Driven by the destruction he witnessed in remote settlements, a hero made it his life’s work to destroy goblins. He works through a guild, accepting missions and improving his standing with each completed task.

The story is based on a series of light novels and introduces a wider range of characters and storylines, including those focused on lizardmen, human kingdoms, and adventurer groups.

‘Mononoke’ (2007)

A wandering healer battles spirits known as Mononoke by first discovering their true shape, origin, and motivation. Each story takes place in a unique setting, like an inn or a boat, and carefully investigates the spirit’s history before attempting to exorcise it.

This series follows a case-by-case format, demonstrating how investigations unfold in various environments. The effectiveness of magical items and spells depends on uncovering the history of each case, meaning that witness statements and concrete evidence are key to solving the mysteries.
