Fantasy anime is full of magical worlds and unforgettable adventures, yet many remarkable series never reach mainstream recognition. On AnimePalm Tv, we explore the most compelling underrated fantasy anime – hidden gems known for strong storytelling, immersive world‑building, and emotional depth.
These overlooked titles may not dominate rankings, but they leave a lasting impact on those who discover them. If you’re searching for something beyond the usual hits, this guide will help you uncover fantasy anime truly worth watching.
What Makes a Fantasy Anime “Underrated”?
Not all great anime trend on streaming charts. Some of the most powerful stories go quietly unnoticed—and that’s exactly what defines an underrated fantasy anime.
Definition of Underrated Anime in the Anime Community
In anime culture, underrated means more than just “not popular.” It describes shows with rich narratives, strong world-building, or artistic value that never got mainstream attention. Many underrated fantasy anime aired at the wrong time, lacked global licensing, or simply didn’t fit algorithmic trends.
Common Reasons Fantasy Anime Get Overlooked
Fantasy anime often compete with trending shounen or seasonal isekai. Many titles are overlooked due to low marketing budgets, unconventional pacing, or incomplete adaptations.
Some lack immediate “hook” appeal but offer layered stories if given time. Others, like Children of the Whales, suffer from being region-locked or under-promoted despite stunning visuals and strong lore.
Difference Between Underrated vs Unpopular Fantasy Anime
The two are not the same. Underrated fantasy anime are high-quality shows with low visibility – hidden gems with storytelling merit. Unpopular anime, by contrast, often fail to resonate due to weak writing or production flaws. Think of Grimgar or The Garden of Sinners: they may not trend, but they leave lasting impressions on viewers who value substance over hype.

Largely overlooked on streaming platforms, it’s a hidden tune in the underrated fantasy anime world.
11. Dog Days

9. Children of the Whales
- Release date: 2017
- Episodes: 12
- Genre: Fantasy, Drama, Mystery
- IMDb: 7.1
Set in a world of drifting sand seas and psychic powers, Children of the Whales is visually stunning and narratively rich. The story follows Chakuro and other inhabitants of the Mud Whale—most of whom carry a curse that shortens their lives. When they encounter an outsider, everything changes. Though beautiful and thought-provoking, the anime ended before fully realizing its potential—making it a standout in the underrated fantasy anime list.
8. Rage of Bahamut: Genesis
- Release date: 2014
- Episodes: 12
- Genre: Fantasy, Action, Adventure
- IMDb: 7.3
Rage of Bahamut: Genesis is high-fantasy anime at its most stylish—dragons, demons, bounty hunters, and ancient seals swirl together in a story brimming with cinematic flair. Powered by MAPPA’s animation and a swashbuckling pace, it captures the feel of an epic RPG brought to life. Despite its excellence, it’s been overshadowed by more mainstream fantasy hits—earning it the top spot in our underrated fantasy anime ranking.
7. A Lull in the Sea
- Release date: 2013
- Episodes: 26
- Genre: Fantasy, Drama, Romance
- IMDb: 7.4
This beautifully animated series tells the story of children from the sea forced to integrate with surface dwellers.

Despite rich storytelling and a lush score by P.A. Works, it never reached global fame—making it a perfect candidate for any underrated fantasy anime list.
6. Grimgar: Ashes and Illusions
- Release date: 2016
- Episodes: 12
- Genre: Fantasy, Drama, Isekai
- IMDb: 7.4
While most isekai anime emphasize power scaling and flashy magic, Grimgar takes a slower, more intimate approach. Characters feel real, their struggles genuine, and death holds permanent weight.

Underrated but deeply impactful, it’s ideal for viewers tired of formulaic tropes.
5. Magi: Adventure of Sinbad
- Release date: 2016
- Episodes: 13
- Genre: Fantasy, Adventure, Action
- IMDb: 7.7
A vibrant prequel to Magi: The Labyrinth of Magic, this series follows Sinbad’s rise from a humble boy to king of the seven seas. Blending folklore with high fantasy, it charts a path of destiny, ambition, and diplomacy. Despite dynamic storytelling and strong visuals, it’s often overlooked due to its status as a spinoff. Yet for fans of epic journeys and charismatic leads, this remains a must-see underrated fantasy anime.
4. Drifters
- Release date: 2016
- Episodes: 12 + OVA
- Genre: Fantasy, Historical, Isekai
- IMDb: 7.6
From the creator of Hellsing, Drifters brings together famous historical warriors like Toyohisa Shimazu and Oda Nobunaga, thrusting them into a brutal isekai world. As fantasy races wage war, these legends battle across dimensions. It’s chaotic, bloody, and unapologetically bold. With sharp writing and intense pacing, Drifters delivers a uniquely entertaining mash-up—but still flies under the radar in most fantasy anime rankings.
3. The Garden of Sinners (Kara no Kyoukai)
- Release date: 2007 – 2013
- Episodes: 7 feature films
- Genre: Supernatural, Mystery, Action, Psychological

From Type-Moon and ufotable, The Garden of Sinners offers a fragmented, meditative exploration of death and identity through the eyes of Shiki Ryougi. Each film unveils a surreal mystery soaked in philosophical dread and quiet introspection. Its cinematic quality is extraordinary, yet it remains under-watched due to its nonlinear structure and niche appeal—making it a crown jewel of underrated fantasy anime.
2. Claymore
- Release date: 2007
- Episodes: 26
- Genre: Dark Fantasy, Action, Gothic
- IMDb: 7.7
Claymore follows Clare, a hybrid warrior tasked with slaying Yoma—shape-shifting demons terrorizing humanity. Set in a bleak, medieval world, the anime dives deep into identity, revenge, and internal conflict. Its intense sword fights, haunting tone, and mature themes stand the test of time. While it didn’t get a full adaptation of the manga, what exists is a gripping tale of strength and sorrow—easily among the best underrated fantasy anime ever made.
1. Now and Then, Here and There
