Adapted from a ten-volume series of novels, this anime stands as one of the most extensive OVA series of its time. Yet, its grandeur was not widely recognized when it was released.

The story unfolds amidst an epic conflict between two interstellar superpowers, focusing on the strategic maneuvers and personal ambitions of their influential leaders.

Blending elements of drama, military tactics, and space opera, its complex themes made it challenging to attract a mainstream audience during its original era.

Premiering in 2012, this series ran for 99 episodes until 2014, faithfully adapting the beloved manga. Its storyline may appear simple, yet it captivates with intriguing themes surrounding UFOs and space exploration.

The anime is often regarded as a Seinen work, focusing on the journeys of two brothers who chase their dream of becoming astronauts. Along the way, viewers are treated to both humor and deeply reflective moments.

Despite its powerful storytelling, "Rainbow" never achieved widespread popularity. The series focuses on boys trying desperately to find hope amidst relentless suffering and cruelty.

Characters like the brutal guard Ishihara and the unsympathetic doctor Sasaki contribute to the intense atmosphere, making life unbearable for the inmates. As a seinen anime, "Rainbow" further distinguishes itself by portraying the boys' later lives in a mature and realistic manner.

Supernatural aspects play a crucial role in the show's commercial appeal, while the underlying romance adds an additional layer of depth and interest for viewers.

However, "Bakemonogatari" has faced criticism for its frequent use of strong language and scenes of violence. The story follows Koyomi, who must navigate the aftermath of surviving a vampire attack and its consequences.

With a stronger emphasis on its horror elements, the series might have attracted a larger audience and achieved greater success.

At first, Nodame Cantabile did not garner widespread recognition, but over time it built a dedicated fanbase. With its realistic portrayal of the world of music, the anime stands out for its depth and authenticity.

In addition to its dramatic depth, Kaiba features moments of romance and levity, further strengthening its case as an outstanding contender for critical recognition.

At its core, Kaiba is a thoughtful and introspective anime. The story encourages viewers to reflect on themes of mindfulness and acceptance.

Despite featuring the enigmatic protagonist who awakens in a vacant room, Kaiba remains relatively obscure. While reviews are scarce, the anime continues to maintain a high ranking among those who have discovered it.

Moribito: Guardian of the Spirit is a 26-episode anime that first aired in 2007. The series was initially met with strong praise from viewers, both domestically and internationally.

Its reception was particularly positive in the American market, earning numerous favorable reviews and achieving significant popularity during that year.

Compared to many other historical-themed anime, Moribito performed remarkably well, likely due to its appeal to a broad, general audience rather than a niche group.

Despite this, the anime did not garner as much attention as one might expect. Fans of the series often find its underrated status quite surprising.

To date, there has been only a single adaptation of this impressive story.

Hyouka is a 22-episode anime that premiered in 2012. The series centers on Houtarou Oreki, a quiet high schooler who unexpectedly gets swept into a series of fascinating mysteries that disrupt his otherwise uneventful life.

Adapted from the renowned "Kotenbu" light novel series, Hyouka echoes the novels' captivating storytelling. Its popularity led to a live-action adaptation in 2017, "Hyouka: Forbidden Secrets," which received praise, though its sequel didn't achieve the same acclaim.

After obtaining new rights holders in 2015, Hyouka gained increased recognition as new viewers came to appreciate its subtle brilliance. The series highlights how everyday moments can hide deep mysteries, challenging audiences to remain invested.

With its meticulously designed mysteries, Hyouka invites viewers to solve the puzzles alongside its characters. Attentive watching is rewarded, as even the smallest details may play a crucial role in unraveling the truth.

"Yona of the Dawn" is a captivating shoujo anime that remains underrated despite its engaging storyline. Released in 2014, the series consists of 24 episodes, drawing inspiration from the original manga.

The narrative follows Princess Yona, whose life changes dramatically after she witnesses a devastating coup. Her family is tragically wiped out in a single night, leaving her to survive on her own in a world filled with danger.

The anime explores Yona's journey as she learns to stand on her own and fights back against the forces that threaten her. Many viewers, especially female audiences, find her growth and resilience deeply relatable and inspiring.

The high risks don't deter the skaters, who are determined to impress with their moves and prove themselves among their formidable peers.

As the series progresses, the intensity rises, revealing remarkable character growth and personal challenges that keep viewers on the edge of their seats.

"Sk8 The Infinity" is the perfect show to binge, offering excitement, drama, and an addictive storyline that's sure to captivate anime fans.

"The 12 Kingdoms" originated as a novel series and later inspired an anime adaptation that aired from 2002 to 2003, spanning 45 episodes. Although it attracted a dedicated niche following, the anime never achieved widespread fame.

The show's premiere reignited interest in all seven light novels, with increased sales highlighting the series' intricate world-building and compelling narrative.

With its masterful blend of magical realism and supernatural fantasy, "The 12 Kingdoms" stands out as a thrilling experience. Despite high praise from critics, it remains largely overlooked, often garnering far fewer reviews than it deserves.

This lack of mainstream attention suggests that the anime hasn't reached as broad an audience as it merits. The story centers on Youko, a young woman longing for normalcy but drawn into extraordinary events.

The plot evolves into a reverse isekai when a mysterious figure appears, leading Youko into untold challenges and opportunities for growth. The anime excels in portraying Youko’s inner journey, highlighting her struggles and the obstacles she must overcome.

Driven by curiosity, Rikuo discovers mysterious activity logs related to Sammy and embarks on a quest to uncover the hidden secrets behind her existence. This intriguing investigation forms the heart of the anime's narrative.

Following its initial release, "Time of Eve" was adapted into a movie. Although neither the series nor the film initially received widespread attention, their compelling storytelling garnered recognition when the anime won the 2010 Tokyo Anime Award.

D.Gray-man has become increasingly popular in recent years, yet its initial run struggled to capture mainstream attention due to limited publicity and exposure. At the time of its original release, this held the series back from reaching the wider audience it richly deserved.

Much like many anime that aired before 2010, D.Gray-man faced obstacles in gaining traction. Although a sequel was later produced, it didn't manage to achieve the same recognition or buzz as the first series.

Notably, the D.Gray-man manga boasted a passionate following long before the anime adaptation was announced. This dedicated community helped maintain interest in the story even when the anime struggled to make waves.

While the anime did not dramatically boost sales of the manga, it played a role in expanding interest and drawing more fans into the D.Gray-man universe overall.

Spanning 103 episodes, the series reached a turning point in 2016 when Funimation secured rights to the latter half, previously held by Dentsu. This new chapter helped revive the franchise, significantly boosting its popularity and bringing it to a broader international audience.

Gunbuster was another sad case of a classic anime that went unnoticed. It’s a space travel-related anime that has “aliens” in it.

They are insectoids who call themselves Space Monsters. They were dangerous aliens who wanted to eliminate mankind.

The story focuses on how Noriko Takaya and Kazumi Amano fight to save the planet.

The anime also shows the internal struggles these two characters go through. The anime was released via OVA in 1988.

It was a time when a lot of alien sci-fi movies came out.

Maybe this was the reason why it did not get the expected response. However, it got popular in the late 2000s.

Soul Eater is a long anime (51 episodes) that was released in 2008. It had run for close to a year on TV.

This anime got a decent ranking and enough votes on myanimelist. It gathered a lot of fans through its source material – manga.

They train Death Scythes who fight the evil forces. The story shows the struggles of these fighters and mankind in fighting evil.

Though the anime became popular later on, it was not known initially. There could be multiple reasons for it.

The series is an adaptation of the original manga, blending humor with the world of baking.

Though it didn't manage to build a massive fanbase, it has consistently held respectable ratings and a loyal following.

Limited reviews make it somewhat under the radar, but that just adds to its status as a hidden gem worth discovering.

The story follows Azuma, a passionate young boy with a unique goal: to create Japan’s very own signature bread, known as "Ja-pan," inspired by countries famous for their breads.

Driven by his dream, Azuma moves to Tokyo, where the series delivers an enthusiastic mix of food, competition, and heartwarming moments.

"Kaleido Star" is a captivating shoujo anime that enjoyed a broad appeal among younger audiences, thanks to its unique blend of sports, drama, and heartfelt storytelling.

With 51 episodes aired over a single year, the series stands out for its vibrant depiction of acrobatics and circus performances—genres rarely explored in anime. Notably, one of the main characters is inspired by a real-life figure, Dio, adding an interesting layer of authenticity to the show.

While the dynamic performances and character development delighted teens and younger viewers, it didn’t strongly resonate with older audiences, which may explain its underrated status.

Despite its safety and suitability for teenagers, "Kaleido Star" struggled to attract significant attention or widespread acclaim, resulting in lower rankings. Nevertheless, this series remains a hidden gem for those seeking inspiring themes and vibrant artistry.

Do you enjoy romance stories that feature love triangles and complicated relationships? If so, School Rumble is an anime you shouldn't miss. The story centers on Tenma and Kenji, who seem destined to be together, yet face a series of humorous and heartfelt obstacles.

As the characters navigate misunderstandings and comedic twists, the anime steadily draws viewers in with its charm and engaging plot. If you're searching for an overlooked gem filled with laughter and heartfelt moments, this is one anime worth watching to the end.

When They Cry is a horror anime that did fairly well, commercially. It was also a success in the reviews.

Critics gave it a reasonable rating. There were a lot of reviews and therefore the ratings were credible.

It was released in 2006 and had 26 episodes. Geneon later gave Funimation the license to distribute it as the performance was not as much as they expected.

Funimation dropped it in 2011 and it was only in 2015 that it found a distributor.

It was Sentai Filmworks. They rebranded and distributed it better. As a result, the sales went up and the anime got justice.

Drifters is a 2016 anime that has 12 episodes. It is an adaptation of its manga.

It is predominantly a Seinen anime with a historical backdrop. Perhaps this was the reason it went unnoticed overseas, for a long.

The protagonist – Toyohisa gets teleported after he is wounded in a battle. He finds the new world strange and tries to blend in.

This assimilation leads him to a warlord – Oda. The rest of it is about the events in the other world.

Paranoia Agent was a 2004 anime that received the Silver prize in animation in the same year.

It has been ranked fairly high and has a decent share of reviews. It had 13 episodes in total.

It was hard to fit it into a single genre. This is because it’s a mix of Supernatural and Dramatic events.

There’s also an element of psychological thrill to it. The tale revolves around 2 detectives – Ikari and Maniwa.

They are on a mission to identify a strange killer. This anime went unnoticed due to poor publicity and a few controversies.

Its source material was also controversial.

Released in 2009, Eden of the East quickly garnered acclaim, winning both the Animation Kobe award and the Best TV Series award that same year.

Despite its early recognition, the anime was initially misunderstood by many viewers, leading to its underrated status in the anime community.

With only 11 episodes and limited resources behind its production, the series might have faded into obscurity if not for the dedicated publicity efforts that gave it a chance to shine.

The story revolves around Akira Takizawa and Saki Morimi, exploring themes of memory loss, identity, and personal responsibility in a uniquely thrilling way.

Though it sparked controversy for its depictions of violence, mature themes, terrorism, and psychological "death games," these bold choices contributed to its depth and appeal for more mature audiences.

Balancing elements of romance, action, science fiction, and mystery, Eden of the East delivers a compelling narrative that continues to attract new fans and deserves greater recognition.

Tsuritama is a unique series originally adapted from its own manga, consisting of just 12 engaging episodes that wrap up swiftly and satisfyingly.

Although often labeled a sports anime, Tsuritama also falls into the shoujo genre and is filled with lighthearted and comedic moments that make it stand out.

While it was initially promoted as a sci-fi series, the story places greater emphasis on the slice of life elements, with science fiction serving more as a subtle backdrop.

This blend of genres may have led to some confusion among viewers, resulting in limited reviews and only moderate ratings.

With wider exposure on OTT platforms, Tsuritama might have gained the popularity and recognition it truly deserves.

"Saenai Heroine no Sodatekata," also known as "Saekano: How to Raise a Boring Girlfriend," is an anime adaptation of a popular light novel series. The story stands out for blending elements of romance, comedy, and slight ecchi themes.

While "Saekano" didn't achieve widespread fame immediately, it eventually gained a dedicated fan base for its relatable characters and unique storytelling. Despite its short run of just 12 episodes, it remains a hidden gem that deserves more recognition.

Hell Girl is a captivating psychological thriller that explores the darker side of human emotions. At the core of this anime lies the mysterious "Hell Correspondence" website, which grants people the ability to unleash their grudges on others.

Overseeing this process is Ai Enma, a stoic girl accompanied by three enigmatic dolls who help her carry out her grim assignments. Users who seek vengeance through the site must pay a heavy price: they too are condemned to Hell after their wish is fulfilled.

This chilling concept of retribution and moral ambiguity sets Hell Girl apart from other anime. The unique narrative has not been explored in similar shows, making it a standout, albeit underrated, experience.

Although Hell Girl received mixed reviews and moderate attention, its originality and unsettling atmosphere remain noteworthy. The anime, adapted from its manga, ran for 26 episodes with a recommended rating of R – 17+ due to intense scenes and dark themes.

A sequel series followed with similar reception, and a movie adaptation garnered criticism for depicting violence and occult rituals. For those seeking a condensed experience, a summary version is also available.

As a mecha anime, it did well. It came out in 2013 when mecha had become an old genre.

The reviews were mixed and the ratings were positive. However, the anime fared poorly, at the box office.

It is a plot that is engulfed in conflict. There is a slow but consistent drag of events in the anime.

Apart from a few directorial and conceptual errors, it was a standard anime.

Later, it got a sequel and some side stories that fared worse than the original anime.

This was a 2014 anime that had just 10 episodes. It was the time when producers were releasing anime on TV rather than OVA.

It received only 19,000 votes on Myanimelist. This is a very less number for such a historical-themed anime.

The plot revolves around a carefree lad named Saburou. He is thrown back into the historical Sengoku era.

Here, he meets General Nobunaga Oda. The anime shows these two people resemble each other.

He is then forced by the General to be a proxy for him. It then goes on to show the difficulties he faces.

This anime also showed the life of the legendary Japanese General. Perhaps the historical niche anime could not impress overseas viewers.

Most of the anime’s commercial success and popularity depends on them. However, anime performed well in Japan.

The mecha anime Infinite Ryvius thrilled the viewers with its epic concept. It was one of the first mecha anime and had released back in 2000.

This was a time when the world had just started to know automation. Though it’s rated at 7.4 on myanimelist, it has very few reviews.

The greater the review, the better its ranking is. You may find 9.0 and above anime with very few reviews.

This is not a reliable indicator. The one with 7.0 having twice or thrice the former’s reviews is more reliable.

This anime also had a touch of spice and military conflicts in it.

The 2005 anime Kamichu! had only 12 episodes. It aired on TV and maybe this led to the lower reach.

It was an era of transition from OVA to TV. Producers during this time had a tough decision to make whether it should be released in OVA format or on tv.

Yurie Hitotsubashi, the protagonist is a simple girl. Her naivety is exposed when she got desperate to make a boy notice her.

There are hilarious scenes when Yurie tries to become the local God. Some of these involve Yurie blessing and cursing people, and attending meetings with other Gods, and even aliens.

This plot contains some slice of life with supernaturalism.

Afro Samurai is an action anime. The adventure element in it complements the action scenes.

It first aired in 2007 in 5 episodes. Later the creators joined hands with some others and made it a movie.

This did well. Afro Samurai has got a decent rank and moderate reviews. Most of it was mixed but never disapproved of the concept.

The protagonist – Afro must find a way to reach number 1. This is to seek revenge for his father’s unfortunate death.

It became more popular as a video game than a manga/anime. This overshadow did not affect the net earnings, much.

"Noir" is a classic anime series from 2001, consisting of 26 gripping episodes. The series was an impressive achievement for its creators, especially since it was an original work without an established fan base.

Following "Noir," two more similarly themed anime were produced: "Madlax," and later "El Cazador de la Bruja" in 2007. Together, these three titles are often referred to as a thematic trilogy.

Within the world of the anime, the name "Noir" becomes synonymous with fear. The show masterfully blends action, drama, and a sense of realism, offering viewers a thrilling experience. Despite its strong qualities, however, "Noir" struggled to find a wide audience and remains an underrated gem.

"Hamatora" is a unique anime series that first aired in 2014, featuring 12 main episodes, along with a sequel and a spin-off adaptation. Despite its creative beginnings, the series struggled to achieve widespread recognition or commercial success.

Originally conceived as a manga, "Hamatora" transitioned into an anime that blends detective elements with mystery and supernatural themes. The title itself is a combination of 'Yokohama' and the Japanese word for 'trouble-shooter,' perfectly capturing its investigative spirit.

Though not officially categorized as a Seinen, the show incorporates mature undertones reminiscent of the genre. Over time, "Hamatora" has garnered a modest but dedicated following, earning its place among underrated anime series.

The Mystic Archives of Dantalian is an adaptation of its light novel. It was released in 2011 with 12 episodes and a side story.

This side story found very few takers. This was also a historical-themed anime. The tale talks about Huey and his grandfather Disward.

Book lovers would love this anime as it’s based on libraries and books. It was one of the best portrayals of supernaturalism in a historical context.

Despite its impressive design work and characterization, it couldn’t get enough views. This can be attributed to poor distribution channels and publicity.

Birdy the Mighty is an adaptation of the manga Tetsuwan Birdy. The anime had 13 episodes and aired in 2008.

It belongs to the category which got decent rankings but a low view count.

It has a reverse Isekai theme which is overshadowed by action. You can call it sci-fi but that would be only a little right.

Cephon Altera, the protagonist is birdy. Birdys are people from the Space Federation. The anime documents Cephon’s life on Earth.

Many light moments went unnoticed in the plot. This anime in one way tried to show us our true selves like a mirror.

Gegege no Kitaro has been largely forgotten and obscure. It could gather only a few reviews and made little commercially.

It was a 2018 anime that concluded in 2020. Maybe it’ll take more time to peak in popularity.

It was a Shounen anime that had a high scope for success. It had the right blend of humor and supernaturalism.

The existence of a “Gegege no Kitaro” makes the plot interesting. It is about a fictional world in the 21st century.

It had a lot of adaptations that were taken from the source material. The manga itself was not popular.

It can still become popular with the right distribution.

Despite his initial skepticism, Tatsuya becomes intrigued by the intensity and camaraderie of Kabaddi. Gradually, he finds himself drawn into the game, eventually becoming a skilled player who comes to deeply respect its traditions and significance.

This concept sold over 14 million copies of its light novels. These novels were the source material for its later manga and anime adaptations.

It was conceptualized in 1996 while the anime came out 3 years later. It had 23 episodes which ran till 2003.

The story is about a young lad named Orphen. He’s a money lender and a financial whiz that operates a cartel in Totokanta.

The anime shows how he got into a series of conflicting issues. These led him to be dragged into a lot of catastrophes.

It went unnoticed because of the poor marketing campaign. Another reason why this was left out was due to the differences that cropped up in the manga and novels.

This spin-off was not a success and left viewers confused.

Princess Principal is a captivating anime series set in a steampunk-inspired version of 19th-century London. The story revolves around a group of five exceptional young girls who are spies for the Commonwealth.

Parody anime often achieve mainstream success, but Samurai Flamenco stands out for walking a different path. Unlike most, it did not receive the attention it deserved during its original run.

Though the anime later inspired a game adaptation, its true charm lies in its unique storytelling and creative take on heroism.

As the series progresses, Masayoshi finds an unlikely ally in Gotou. Spanning 22 episodes released over a year, the anime explores their evolving partnership and the obstacles they face.

Although some critics took issue with the violence and strong language, Samurai Flamenco has been praised for its supernatural humor and clever parody elements that make it genuinely entertaining.

Fractale is an adaptation of the manga of the same name. It was engulfed in controversy soon after its release in 2011.

Mutsumi, the designer of the manga wrote a blog saying the work was “uninteresting”.

Though it was removed soon, it had stirred a hornet’s nest. The director then told the production committee to discontinue the manga.

Though Mutsumi apologized later, the damage was done. It was a simple plot that showed the events on an island and its secret.

One of the main reasons it went underrated was this controversy. The creators had lost their morale.
