Top 10 Underrated Fantasy Anime That Deserve a Second Season (No Isekai)
- May 7
- 14 min read
Fantasy anime has been dominating the anime space for years, especially as more people search for things like “anime to watch,” “watch anime free,” and “new anime” online. While many fans discover the genre through massive hits like Dragon Ball Z, Yu-Gi-Oh!, and the global phenomenon Pokémon, these only scratch the surface of what fantasy anime really offers.
From overpowered battles to magical creatures and immersive worlds, fantasy anime comes in many forms. Some series lean toward futuristic elements, while others dive deep into classic medieval settings filled with magic, swords, and adventure—the kind of supernatural anime that fans are constantly searching for.
In this list, I’m focusing specifically on true fantasy anime—series set in worlds driven by magic, kingdoms, monsters, and exploration. While popular titles like Solo Leveling, Is It Wrong to Try to Pick Up Girls in a Dungeon?, and Delicious in Dungeon dominate most anime lists, there are plenty of underrated shows that deserve just as much attention.
If you’ve ever spent time browsing anime websites or platforms like Crunchyroll trying to find something new, you already know how hard it can be to discover hidden gems. That’s exactly what this post is for.
One important note: I will not be including isekai anime. While isekai often overlaps with fantasy, it typically brings modern concepts into the world, which takes away from that pure medieval fantasy feel. Series like The Eminence in Shadow, Tsukimichi: Moonlit Fantasy, and That Time I Got Reincarnated as a Slime are popular for a reason—but they’re not the focus here.
Instead, this list highlights underrated fantasy anime—the ones that may not appear in every “top anime to watch” search but absolutely should. These are series with one to three seasons that have strong potential and deserve a second season.
To keep things fair, I’ll also be excluding any anime that are already confirmed to be getting another season.
How I’m Ranking These Anime
To build this list, I’ll be focusing on:
Animation – Visual quality, fight scenes, and overall style
Story – Worldbuilding, creativity, and engagement
Characters – Memorable vs generic casts
Pacing – Growth, progression, and future potential
Overall Opinion – Whether it’s actually worth your time
10. The Hidden Dungeon Only I Can Enter
Story
This anime follows a lower-class noble who suddenly gains a powerful ability that lets him manipulate reality and increase his strength. The catch? He powers up by doing things he enjoys—like eating good food, having fun… and yes, a lot of lewd activities.
As expected, this leads to a classic harem setup. He quickly gathers multiple girls around him while going on adventures, attending school, and steadily growing stronger. The story doesn’t take itself too seriously—it leans heavily into fan service and lighthearted fantasy rather than deep worldbuilding.
Animation
The animation is pretty standard overall. Nothing groundbreaking here—most of the visual effort clearly goes into the fan service. Expect exaggerated character designs, especially when it comes to female characters.
Outside of that, the animation is very generic by anime standards. It gets the job done, but it’s not something you’ll remember for its visuals.
Characters
This is where the show can be hit or miss. The main character is young and quickly becomes surrounded by multiple love interests, which feels very typical for this kind of anime.
He doesn’t go through much emotional growth, and most of his development is tied to gaining power rather than maturing as a person. The relationships are more about the harem dynamic than meaningful character progression.
Pacing
The pacing is exactly what you’d expect from a fantasy harem anime. He builds relationships almost immediately, gains companions early on, and moves between school life and adventuring.
Since he’s not overwhelmingly overpowered from the start, there’s at least some progression—but overall, it’s a relaxed, easy-to-watch series rather than a high-stakes one.
My Opinion
Let’s be honest—this one is definitely aimed at a specific audience. It’s a “for the boys” kind of anime, filled with fan service, comedy, and light fantasy elements.
That said, it is genuinely funny at times, and if you go into it knowing what to expect, it can be an enjoyable watch. It’s not deep, but it’s entertaining—and that’s why it earns a spot on this list.
9. I Parry Everything
Story
This anime takes a very different approach. It follows a boy who dreams of becoming an adventurer after losing his mother. However, he discovers he lacks talent in most areas—except for one thing: basic defensive skills like parrying.
Instead of giving up, he trains relentlessly, mastering the fundamentals to an extreme level. Ironically, this makes him incredibly strong. Because of his lack of awareness about how powerful he actually is, he ends up taking on threats far above his level—while thinking they’re simple tasks.
This leads to a mix of comedy, action, and surprisingly heartfelt moments.
Animation
The animation here is also fairly standard. There are some solid moments during fights, but overall it doesn’t stand out much.
Monster movement and certain battle scenes can feel a bit underwhelming, which shows the limitations of the production. Still, it’s consistent enough to support the story.
Characters
This is where the anime really shines. The main character has strong development and emotional depth. Losing his mother shapes his journey, and his determination to improve makes him very easy to root for.
He’s also unintentionally humble due to his lack of awareness, which leads to both comedic and meaningful moments. Unlike many fantasy protagonists, he actually grows—not just in strength, but as a person.
Pacing
The pacing focuses less on gaining new abilities and more on how his actions impact the world around him.
His journey influences others—teaching humility, perseverance, and kindness. Instead of flashy power-ups, the story emphasizes growth, relationships, and the ripple effect of his actions.
My Opinion
I genuinely love this anime. It’s wholesome, funny, and inspiring without relying on fan service or harem tropes.
Watching the main character overcome his limitations through hard work is incredibly satisfying. It also shows that success isn’t just about talent—you need support, community, and persistence.
It’s a feel-good fantasy anime with emotional depth, and I highly recommend it if you want something more meaningful.
8. The Ossan Newbie Adventurer, Trained to Death by the Most Powerful Party, Became Invincible
Story
This one follows a familiar—but still fun—concept: an underdog who doesn’t realize how strong he really is. The twist? He’s not a teenager—he’s in his 30s, chasing a dream that most adventurers start pursuing in their teens.
Because of this, he’s constantly underestimated and even mocked. But what people don’t know is that he trained under an S-rank party, pushing himself to the brink over and over again. The result? He’s insanely strong—not because of overwhelming magic, but because of mastery and control over the basics.
Animation
This is where the anime steps things up. Compared to the previous entries, the animation quality is noticeably better.
The fight scenes and magic effects are visually appealing and more polished. It’s not on the level of Solo Leveling, but it’s definitely a step above standard fantasy anime visuals.
Characters
Character development here is interesting. Since the protagonist starts off already strong, his growth isn’t about gaining power—it’s about understanding his worth and impact.
What stands out is how his journey influences others. From fellow adventurers to people in his past life (like guild staff), he helps others grow while reflecting on his own struggles and training.
Pacing
The pacing is a bit unusual. He becomes established as powerful very early on, but the story shifts toward bigger goals—like exploring dangerous areas and searching for powerful enemies tied to long-term objectives.
There’s still plenty of room for growth, especially since he isn’t completely overpowered to a “god-tier” level. The story feels like it’s building toward something bigger.
Overall Opinion
This anime is fun, comedic, and surprisingly motivating. The contrast between how strong he actually is and how casually he treats it creates a lot of great moments.
It balances humor with backstory and character moments, making it an enjoyable watch. Definitely one that deserves more attention—and a second season.
7. The Most Notorious Talker Runs the World's Greatest Clan
Story
This anime takes a darker and more grounded approach to fantasy. The protagonist has one of the weakest classes—“Talker”, a support role focused on buffs and debuffs rather than direct combat.
After being betrayed by his own party, he sets out to rebuild from scratch. But instead of taking the usual heroic route, he operates in a much more realistic and morally gray world.
This isn’t a clean, heroic fantasy—he deals with crime, corruption, betrayal, and harsh consequences. He doesn’t just defeat enemies—he outplays them strategically, sometimes in brutal ways.
Animation
The animation here is solid and stands out more than earlier entries. Character designs are sharp, and the fight scenes are more dynamic.
There’s a strong sense of style, especially in how characters are presented. It feels more refined and visually engaging than many underrated anime.
Characters
This is where the anime really hits. The protagonist isn’t your typical hero—he’s calculated, cold when necessary, and shaped by a dark past.
His actions can be extreme, but they make sense within the world he lives in. This creates a cast of characters that feel human, flawed, and realistic, rather than idealized.
Pacing
The pacing is slower, focusing on strategy, rebuilding, and forming alliances.
He doesn’t instantly form a powerful group—instead, he carefully builds his team over time. By the end, his journey is just beginning, leaving a lot of room for future development.
Overall Opinion
This is one of the darker fantasy anime on the list, and that’s what makes it stand out.
It’s strategic, grounded, and filled with morally complex decisions. If you’re tired of overpowered protagonists solving everything easily, this is a refreshing change.
6. Apparently, Disillusioned Adventurers Will Save the World
Story
This anime focuses on a group of broken individuals who come together after being betrayed or hurt in their past lives.
The main character, Nick, is kicked out of his party and loses trust in others. Instead of jumping straight back into adventuring, he falls into everyday coping habits—like obsessing over idols.
He eventually meets others with similar struggles: a gambler, a former noble, and others dealing with their own issues. Together, they form a party—not because they trust each other, but because they understand each other’s pain.
Animation
The animation is solid and consistent. It’s not flashy, but it fits the tone of the story.
There’s a slightly grounded, almost realistic feel to the visuals that matches the emotional weight of the characters.
Characters
This is easily the strongest part of the anime.
Unlike most fantasy anime that focus on one overpowered protagonist, this story develops the entire party. Each character has real flaws, past trauma, and emotional struggles.
The growth feels natural and happens gradually, making their journey feel meaningful.
Pacing
This is a slower-paced anime, focused heavily on character development rather than action.
The story takes its time building trust between the characters. Even though the title suggests saving the world, the anime is more about personal growth—and it’s clear there’s much more story left to explore.
Overall Opinion
This is a standout underrated fantasy anime.
It focuses on emotional growth instead of power scaling, which is rare in the genre. Every episode builds on the characters and their relationships, making you want to keep watching.
If you’re looking for something deeper than typical fantasy anime, this is a must-watch.
5. The Brilliant Healer's New Life in the Shadows
Story
This follows a classic setup: a healer from a top-tier party gets kicked out because they think he’s useless… only to realize later he was actually carrying the entire team.
After being cast aside, he ends up in the slums and opens a black-market clinic, helping people who can’t afford proper treatment. Along the way, he builds connections—mainly with powerful women (yes, it turns into a bit of a harem).
He later enrolls in a healer academy and, unsurprisingly, turns out to be far more skilled than anyone else. The story mixes underground clinic work, school life, and hints of larger threats.
Animation
The animation is very standard for anime. Nothing too flashy, but also nothing bad.
Character designs are grounded, and the fight scenes follow typical fantasy anime patterns. It’s consistent, just not visually standout.
Characters
The protagonist doesn’t grow much in terms of power—he’s already extremely strong.
However, what’s interesting is the growth of the people around him, especially those in the slums. Watching them rise alongside him gives the story some charm.
Pacing
The pacing is quick but not rushed. You meet most of the main cast early, and the story moves through key events like saving patients, attending school, and dealing with hidden enemies.
There are clear hints at a bigger villain that hasn’t been fully explored yet, leaving room for future seasons.
Overall Opinion
This anime is more on the cute and lighthearted side. It has a few lewd moments, but overall it’s easy to watch and even rewatch.
If you enjoy healer-type characters (think support roles in RPGs), this one is especially fun. It’s not the deepest story, but it’s entertaining and has some genuinely funny moments.
4. Kino's Journey: The Beautiful World
Story
I know, I know—this isn’t strictly medieval fantasy, even though some of the worlds Kino visits definitely have that feel. But it’s still one of the most unique anime on this list, and it deserves a spot.
It follows a traveler named Kino (whose gender is intentionally ambiguous) and a talking motorcycle as they journey between isolated countries. Each episode focuses on a new place with its own rules, culture, and philosophy.
Some of these stories are simple, while others are deeply unsettling or thought-provoking—like a society where killing is legal and normalized.
Animation
The animation is simple but effective.
What really stands out is the design of each country. Every location feels distinct, helping bring each story to life.
Characters
This isn’t a character-growth-driven anime.
Instead, it focuses on how the viewer reacts to the stories. Kino remains relatively consistent, acting more as an observer than someone who changes dramatically.
Pacing
The pacing is episodic. There’s no single overarching plot—just a series of short, self-contained stories.
Each episode introduces a new concept or moral question, making it perfect for viewers who enjoy slower, more reflective storytelling.
Overall Opinion
I loved this anime because it makes you think.
It feels similar to anthology-style series like Black Mirror or The Twilight Zone. If you enjoy stories that challenge your perspective, this is a must-watch.
3. Goblin Slayer
Story
This is one of the darkest fantasy anime out there.
Instead of glorifying adventure, it shows the brutal reality of a world filled with monsters—especially goblins. These creatures are far more dangerous and disturbing than most fantasy stories portray.
The protagonist dedicates his life to hunting goblins after experiencing severe trauma. The story explores violence, survival, and psychological damage, making it much more grounded than typical fantasy anime.
Animation
The animation reflects the tone—dark, gritty, and realistic.
It doesn’t shy away from showing the harshness of the world, which makes it very much an adult-oriented anime.
Characters
The focus isn’t just on the main character—it’s on how trauma affects everyone around him.
You see how encounters with goblins leave lasting mental and emotional scars, adding depth to the story.
Pacing
The pacing is steady, focusing on missions rather than a “save the world” plot.
There are hints of a larger threat (like the goblins’ origins and hierarchy), leaving a lot of room for expansion in future seasons.
Overall Opinion
This anime is not for everyone due to its dark content.
But if you can handle it, it’s incredibly well done. The strategy, tension, and realism make it stand out. It’s one of the strongest entries here and absolutely deserves more continuation.
2. My Daughter Left the Nest and Returned an S-Rank Adventurer
Story
This story flips expectations by focusing not on the powerful adventurer—but on her father.
The daughter is an S-rank adventurer known across the land, but the heart of the story is her relationship with her father, who raised and trained her. Despite being officially ranked low, it’s clear he’s much stronger than he appears.
The story revolves around their bond, their separation, and how their lives continue to impact each other.
Animation
The animation is simple and clean.
It doesn’t aim for flashy visuals—instead, it supports the warm and emotional tone of the story.
Characters
Both the father and daughter experience meaningful growth.
The father learns to live without her while still longing for her return, and the daughter continues to grow while carrying his teachings with her.
Even side characters develop through their interactions with them.
Pacing
The pacing balances slice-of-life moments with hints of larger threats—like recurring enemies and dark forces in the world.
There’s a lot of potential for expansion, especially with the worldbuilding and side stories.
Overall Opinion
This is one of the most wholesome fantasy anime on the list.
It’s a refreshing change from typical tropes and focuses on genuine relationships. If you want something heartfelt and meaningful, this is a must-watch.
1. My Gift LVL 9999: Unlimited Gacha
Story
This anime starts with a weak protagonist who has a seemingly useless ability: a gacha system that gives random low-tier items.
After being betrayed and thrown into a dangerous dungeon, he discovers the true power of his ability—allowing him to summon incredibly powerful beings and items.
He quickly becomes extremely overpowered (level 9999) and sets out on a path of revenge against those who betrayed him.
Animation
The animation is one of the strongest on this list.
The summoned creatures, magic effects, and large-scale battles are visually impressive and feel much more dynamic than most underrated fantasy anime.
Characters
Character development happens fast—he goes from weak to overpowered early on.
After that, the focus shifts to his revenge and uncovering the mystery behind his power, especially the concept of “Maestros” and others like him.
Pacing
This anime is packed with mystery.
There are so many unanswered questions:
What are Maestros?
Why was he targeted?
Who else has this power?
This constant sense of unknown keeps the story engaging and leaves a lot of room for future seasons.
Overall Opinion
This is one of the most addictive anime on the list.
Every episode leaves you wanting more, especially with how much is still unexplained. The revenge storyline, combined with the mystery, makes it incredibly engaging.
Out of all the anime here, this is one of the ones that most deserves a second season.
Honorable Mentions
Not every great fantasy anime can make the top 10, but there are still plenty of underrated anime worth watching that deserve recognition.
Some of these are similar in style to the ones on the list. For example, Let This Grieving Soul Retire has a really interesting twist—it’s almost the reverse of I Parry Everything. Instead of a hardworking underdog who becomes strong, the protagonist here is more of a bumbling, clueless character… but everything he does somehow works out perfectly. Whether it’s luck or coincidence, people around him start to see him as a genius strategist. It gives off strong Overlord vibes, where perception is everything.
Other anime fall into this category because they already have multiple seasons announced, completed their story, or don’t need a continuation, even though they’re still fantastic fantasy series. Titles like From Old Country Bumpkin to Master Swordsman and Banished from the Hero's Party, I Decided to Live a Quiet Life in the Countryside are great examples—they’ve either progressed far enough or wrapped things up in a satisfying way.
Even though they didn’t make the main list, these are still hidden gems. They’re not always the most searched or mainstream “anime to watch,” but they’re absolutely worth your time—especially if you enjoy pure fantasy anime that isn’t isekai.

Conclusion:
Fantasy anime has always been one of the biggest and most loved genres out there. From classics like Dragon Ball Z and Inuyasha to newer hits like Solo Leveling, the genre continues to grow and evolve. It’s not just limited to anime either—you can see its influence everywhere, from tabletop games like Dungeons & Dragons to massive titles like Dark Souls and Elden Ring. There’s just something about swords, magic, dragons, and medieval worlds that never gets old.
While major titles dominate platforms like Crunchyroll, there are still plenty of underrated fantasy anime that don’t get the attention they deserve.
That’s what this list was about—highlighting those hidden gems. These are the anime that might not always show up when you search for “anime to watch,” but still deliver great stories, memorable characters, and unique worlds. Whether it’s the wholesome journey in My Daughter Left the Nest and Returned an S-Rank Adventurer, the dark and gritty tone of Goblin Slayer, or the mystery and hype behind My Gift LVL 9999: Unlimited Gacha, each one brings something different to the table.
At the end of the day, all of these anime have something worth watching—whether it’s strong storytelling, character development, or just pure entertainment.
If you’ve already seen some of these, I’d love to hear what you think. And if you have other underrated fantasy anime that deserve another season, share them—there are always more hidden gems out there, and they deserve to be seen.
