The Most Underrated Anime of 2025 — Why No One Talks About These Gems?

2025 has been a year overflowing with anime releases — sequels, adaptations, and brand-new originals are hitting screens faster than anyone can keep up with.

But while the hype often gravitates toward the loudest titles, there are hidden gems quietly redefining the anime landscape. These underrated series are not just “good”; they are revolutionary in storytelling, character development, and visual artistry, yet somehow remain in the shadows.

For anime fans seeking the next big thrill, the next mind-bending plot, or just a series that makes the heart race and the mind think, 2025 has delivered in subtle, unforgettable ways.

From action-packed thrillers to heartwarming magical adventures, these shows are quietly carving out their legacies, waiting for viewers to notice.

This article dives deep into nine underrated anime that deserve your attention — from Sakamoto Days to Lord of Mysteries — highlighting why these series are worth your watchlist this year.

Why 2025 Is a Year of Underrated Masterpieces

The anime industry today is more crowded than ever. Big-name franchises dominate social media trends, leaving smaller, niche, or experimental titles overlooked.

However, the overlooked titles often provide unique storytelling, innovative art, and compelling character growth that mainstream anime struggles to offer.

In 2025, this dynamic has never been more apparent. With new seasons, adaptations, and bold originals hitting the scene, several anime quietly deliver experiences that are as emotionally impactful as they are visually stunning — and yet, most of these gems remain largely unrecognized outside dedicated fan circles.

The Underrated Anime Gems of 2025

Sakamoto Days

Kicking off the year, Sakamoto Days surprised fans with its clever mix of action and humor. The story follows Taro Sakamoto, a once-feared hitman now living a peaceful life as a grocer.

The contrast between his violent past and mundane present allows the series to explore themes of redemption, family, and the value of everyday moments — all while delivering intense, visually stunning action sequences.

Unlike typical shonen protagonists chasing power, Sakamoto is an older, content man whose strength is inherent, not aspirational. Studio CloverWorks brings the narrative to life with dynamic fight scenes, crisp animation, and comedic timing that elevates the storytelling. Despite its brilliance, the anime has flown under the radar, overshadowed by bigger franchises, making it a must-watch hidden gem.

Solo Leveling Season 2

Also debuting in January, Solo Leveling Season 2 continues the saga of Sung Jin-Woo, the S-rank hunter navigating increasingly dangerous dungeons. The second season delves into darker territories, exploring both his growing powers and the geopolitical conflicts among hunters.

Studio A-1 Pictures maintains their signature visually rich animation style, turning each dungeon exploration into a cinematic thrill ride.

While fans of the manga eagerly awaited its adaptation, the sheer volume of releases in 2025 caused the season to be slightly underappreciated — despite its complex characters, breathtaking action, and world-building that rivals any blockbuster series.

Fire Force Season 3

The third season of Fire Force, slated for April, ups the stakes dramatically. Following the Great Cataclysm arc, Shinra Kusakabe’s journey intersects with religious conspiracies, supernatural phenomena, and internal conflicts within the Fire Force brigades.

David Production delivers fluid, high-octane battles with explosive pyrotechnics and seamless choreography. The season also emphasizes character development, exploring tensions within the 8th brigade and deepening Shinra’s role as a savior figure.

Despite its adrenaline-pumping narrative, the anime quietly slipped under mainstream attention due to overlapping releases in the same season.

Wind Breaker Season 2

Adapted from the Korean webtoon by Yongseok Jo, Wind Breaker Season 2 brings back Jo Ja-Hyun for more high-stakes cycling adventures.

The anime explores his growth as an athlete and a person, along with evolving friendships and rivalries among his team.

CloverWorks ensures the animation captures every heart-pounding race and emotional moment. While sports anime often gets niche recognition, this series blends adrenaline and heartfelt storytelling in a way that deserves wider acclaim, making it a quiet standout of 2025.

Gachiakuta

Gachiakuta is a daring adaptation of Kei Urana’s dark manga, presenting the story of Rudo, a boy condemned to the Abyss — a monstrous world where he must survive and seek vengeance. With its intense action, dark social commentary, and striking visuals, the series pushes shonen conventions while exploring mature themes.

Studio Bones brings Rudo’s chaotic journey to life with epic battles and meticulously crafted settings. Yet, its unique artistic style and dark narrative make it a slow-burner for mainstream viewers, contributing to its underrated status despite its immense potential.

Witch Hat Atelier

In stark contrast, Witch Hat Atelier offers serene, meticulously crafted magical storytelling. Coco, a young girl learning magic through runes and ink, explores a world where enchantment is hidden from most.

Studio BUG FILMS, under Ayumu Watanabe’s direction, translates Kamome Shirahama’s manga into a visually stunning, faithful adaptation. The series’ calm pacing, delicate artistry, and immersive world make it one of the year’s most underrated magical adventures, overshadowed by faster, flashier titles.

Omniscient Reader

Based on the Korean webtoon by Sing N Song and UMI, Omniscient Reader centers on Kim Dokja, a man who becomes a key figure in an apocalyptic world drawn from his favorite web novel. His knowledge of the plot gives him unique strategic advantages, blending fantasy, sci-fi, and survival game elements.

MAPPA’s animation captures high-stakes battles and pivotal twists with flair. Despite its complex narrative and intellectual depth, the anime has remained underrated, likely overshadowed by other Korean adaptations like Solo Leveling.

Undead Unluck

Returning for its second season, Undead Unluck explores the adventures of Andy and Fuuko as they challenge fate itself. The season dives deeper into the Union organization, expands the concept of unique negation powers, and pushes the boundaries of narrative creativity.

Yoshifumi Tozuka’s original manga is faithfully adapted, balancing dark humor, action, and philosophical musings on fate. Though Winter 2025 releases were crowded, this series remains a bold, underrated masterpiece.

Lord of Mysteries

Finally, Lord of Mysteries transports viewers into a Victorian-inspired universe filled with magic, danger, and secret societies. Klein Moretti, armed with modern knowledge and newly acquired supernatural powers, navigates an enigmatic world filled with occult rituals and mystical intrigue.

B.CMAY PICTURES animates the adaptation with a careful eye for detail, ensuring magic sequences and mystical entities feel both realistic and awe-inspiring. The complex lore and deliberate pacing make this one of 2025’s quietest but most intellectually rewarding anime experiences.
