In the last few years, anime has skyrocketed in both popularity and quantity, with every season featuring at least one title the community latches onto as a definitive smash hit. From massive shonen anime franchises like Demon Slayer to gems that unexpectedly break into the mainstream like Dungeon Meshi, some of the best titles in modern anime either debuted or peaked in popularity in the 2020s.
However, their astronomical success often overshadows equally incredible series that, alas, enjoy much more moderate popularity. Put on the back burner and buried in fans’ ever-expanding to-watch lists, some of the best anime to premiere in the last 5 years are underrated gems most regrettably overlook. There’s no time like the present to give these fantastic series the attention they deserve.

10 The Heike Story Presents Real-Life History as Gripping and Full-Hearted
Streaming on Crunchyroll
Historical fiction – particularly works that prioritize realism – has always been an underrated genre within anime, but some of the most compelling epics happen to lurk in tales of the past, as proven by The Heike Story’s rendition of the Taira clan’s rise and fall.
A fictionalized retelling of a principal 13th-century historical text, The Heike Story’s brings the past to life in a wonderfully artistic manner, as to be expected from a collaboration between studio Science Saru and director Naoko Yamada (A Silent Voice, K-On!). Being Yamada’s first work after departing from Kyoto Animation, The Heike Story excels at combining the director’s naturalistic style with Science Saru’s famously experimental aesthetics, resulting in a fantastic anime that feels both magical and true to life.
9 Malevolent Spirits: Mononogatari Is a Regrettably Overlooked Entry in Anime’s Ever-Growing Supernatural Genre
Streaming on Crunchyroll

From Jujutsu Kaisen to Dandadan, tales of spirits have been on the rise in mainstream anime in the last few years. Yet, one of 2023’s best supernatural anime, Malevolent Spirits: Mononogatari happened to fly under the radar despite how excellently the series tackles the theme. The heir of the Saenome family, Hyoma Kunato, is set to inherit their craft of peacefully dealing with Tsukumogami – spirits that possess inanimate objects.

10 Best Supernatural Anime, Ranked
There are tons of supernatural anime out there, but Fruits Basket and Spirited Away still prove themselves among the genre's best.
Yet, a past traumatic experience led to Hyoma’s deep hatred of the Tsukumogami – something his grandfather wants to fix by placing Hyoma in the care of a Tsukumogami family. As far as supernatural anime go, Mononogatari is much less action-oriented than most, its focus favoring character-driven storytelling and nuanced exploration of folk mythology – a direction many would undoubtedly appreciate.
8 All Saints Street Is a Cozy Comedy About Mythical Creatures Coexisting in the Human World
Streaming on Crunchyroll

Urban fantasy and slice-of-life comedy are not two genres that intermingle often. In All Saints Street, they do so in more ways than one, resulting in one of the medium’s most peculiar yet endearing comedic experiments.
A Chinese ONA set in a world where humans and all sorts of mythological creatures – from vampires and werewolves to angels and demons – peacefully coexist, All Saints Street follows the daily hijinks of Apartment 1031 residents, all of whom happen to be unearthly beings. The unique art style and an even more out-there sense of humor make All Saints Street a comedy which, while not particularly daring, attracts audiences with everything that sets it apart from your run-of-the-mill gag anime.

5 Link Click Tackles Time Travel from a Profoundly Genre-Bending Perspective
Streaming on Crunchyroll
While having an incredibly devoted cult following, the Chinese animated series Link Click never quite made it to mainstream levels of popularity – despite being one of this decade’s most stellarly written and compelling titles. An unorthodox take on time travel, the anime uses photos as a means to influence the present through snapshots of the past.
Lu Guang can see 12 hours into a photograph’s future, and his partner, Cheng Xiaoshi, can dive into pictures by possessing the photographer – albeit they agree to never interfere with past events in ways that might disturb the flow of time. Combining episodic storytelling focused on various people’s poignant tales of regret with a gradually unraveling mystery-thriller plot, Link Click crafts a phenomenally engaging narrative that never fails to surprise the viewers with both its emotional depth and unpredictable developments.

4 Backflip!! Is a Must-Watch for All Sports Anime Enthusiasts
Streaming on Crunchyroll

The sports genre is a rare category of anime where the quality is decided less by the broad strokes of uniqueness or conceptual appeal and more by the nuances that go into crafting a compelling, relatable narrative. Backflip!! – a 2022 anime about Shoutarou Futaba, who, on a whim, decides to join a competitive gymnastic team – doesn’t break new ground when it comes to the sports anime formula.
Backflip!!’s stellar execution of the fundamentals – with just enough personalized flair – makes it a standout exemplar of the genre. Filled to the brim with lovable characters, compelling development, and visual excellence, Backflip!! has a strong grasp on what makes the sports genre such a fan-favorite within the anime community - which makes its lack of popularity that much more damning.

2 The Tatami Time Machine Blues Was Unfairly Overlooked Even by Fans of Its Prequel
Streaming on Hulu

The original Tatami Galaxy anime directed by then-little-known auteur Masaaki Yuasa has a cult following within the anime fandom, the series still relevant despite being released 15 years ago. Its 2022 sequel produced by Yuasa’s studio Science Saru managed to sneak by both modern audiences and some long-time fans of the series.
The Tatami Time Machine Blues reunites the viewers with the familiar characters, who once again are thrust into eccentric, reality-bending antics – this time concerning the unpredictable consequences of meddling with the past. A rare modern spin-off of a cult-classic anime that is just as good as the original, The Tatami Time Machine Blues is not just a must-watch for fans of The Tatami Galaxy but also an excellent incentive for new fans to give both series a shot.
1 Sonny Boy Takes an Experimental Approach to Breaching Universal Coming-of-Age Themes
Streaming on Crunchyroll
One of the most unique anime of the 2020s, Sonny Boy entices the viewers with its mysteries from the very first moments. A class of regular children suddenly finds themselves – together with their school building – stuck in an endless void dimension. Moreover, some of them awaken peculiar superpowers, leading to an immediate spark of conflict.
A reality-bending series that follows the kids’ struggle to escape - and survive - this paranormal predicament, Sonny Boy is an incredible character-driven mystery that combines the appeal of its puzzling plot with insightful commentary on interpersonal conflicts and turmoils of adolescence. A beautifully executed, thought-provoking fulfillment of a clever isekai premise, Sonny Boy is a modern classic that definitely deserves more attention.
