Casandra Ronning is a staff writer for Screen Rant's anime section. Since mid-2024, she has dedicated herself to expanding her knowledge and experience in the entertainment industry. She is most proud of conducting an exclusive interview with popular voice actor Stephanie Nadolny.

Seinen anime are series that target adult males but often have universal appeal, drawing in global audiences with their mature storytelling and willingness to explore themes that range from dark and psychological to relaxing and heartfelt. Given its demographic, seinen has the ability to tell stories that aren’t restricted in ways that shōnen might be, often allowing its stories to take creative and narrative risks that resonate with older audiences on a deeper level.

While there are plenty of longer seinen anime series that are easily considered masterpieces, there are also many shorter series with fewer than 13 episodes that equally deliver unforgettable experiences. Through these shorter series, all of which are available to stream on Crunchyroll in most regions, anime fans can enjoy some of seinen’s finest works without having to commit to dozens of episodes while still enjoying unforgettable stories and strong characters.

Erased

Released in January 2016, Erased centers on a struggling manga artist named Satoru Fujinuma who has the unique ability to travel back moments in time to prevent fatal tragedies from striking. However, after the murder of someone close to him, he’s unexpectedly sent 18 years into the past, where he must solve a series of kidnappings and murders to rewrite his present and save those he cares about.

The series stands out for its suspense and tension, effectively keeping audiences glued to their seats from start to finish. With its mature themes, including childhood abuse and isolation, the story leaves behind a profound impact on viewers that’s impossible to forget. Paired with Erased’s fast-paced writing, the story never falters or drags while still respecting its heavy subject matter, making it a must-watch seinen thriller.

With only 12 episodes, the series can easily fit into busy schedules or a weekend binge. Audiences who enjoy psychological thrillers and mysteries will find that Erased provides a heavily rewarding experience. However, given that the anime slightly alters the manga’s conclusion, some fans admittedly have gripes about the ending, while others will find it fitting. That said, the story Erased tells is a can’t-miss anime that deserves every bit of recognition it gets.

Odd Taxi

Odd Taxi released in April 2021 and has a deceptively simple premise that gradually expands into one of anime’s strongest mysteries. The series follows Hiroshi Odokawa, a walrus taxi driver whose nightly fares introduce him to a range of people who all carry their own goals and burdens. What begins as a slice-of-life story of seemingly unconnected encounters then grows into a larger mystery surrounding the disappearance of a teenage girl who was last seen in Odokawa’s cab.

Every conversation in Odd Taxi, no matter how seemingly mundane they might be, serves a larger purpose, rewarding audiences for close attention to detail and making the series stand out for its masterful foreshadowing. While the series may seem lighthearted due to the charming animal designs, the story explores themes of obsession and loneliness as well as celebrity culture and the impact of social media.

With these mature themes and overarching mystery, Odd Taxi offers an incredibly satisfying payoff. Every revelation reframes how earlier scenes are interpreted, allowing each episode to build and grow stronger before reaching the well-executed ending. Audiences who enjoy slow-burn suspense and character-driven storytelling will find that Odd Taxi delivers an unforgettable mystery in just 13 episodes, making it a perfect short watch to add to any anime watchlist.

Mononoke

Mononoke takes place in feudal Japan, following the mysterious, nameless man who goes only by the Medicine Seller. He travels from one haunted location to the next, confronting vengeful supernatural entities who are born of unresolved suffering known as mononoke. Each case is a self-contained mystery that requires the Medicine Seller to figure out the mononoke’s Form, Truth, and Reason before he can draw his Exorcism Sword to banish the spirit.

The series was released in July 2007 and stands out most for its uniquely stylized animation, filled with eye-catching vibrant colors and gorgeous artwork. Paired with its atmospheric storytelling and thematic depth, Mononoke is a one-of-a-kind series that tackles themes of guilt, regret, trauma, and despair through the mononoke, who are the manifestations of these heavy emotions and experiences.

As a supernatural horror anime, Mononoke creates a sense of unease with every self-contained story. With only 12 episodes and three films, Mononoke can fit into nearly any schedule, especially given that its arcs are all self-contained and easily watched in two or three parts. Anime fans who enjoy slow-burning and thought-provoking stories will find the anime to be a visually extraordinary and worthwhile experience.

Yakuza Fiancé: Raise wa Tanin ga Ii

Yoshino Somei hugging Kirishima Miyama and pulling down the back of his shirt to reveal his tiger tattoo

Released in October 2024, Yakuza Fiancé centers on two rivaling yakuza families who negotiate an arranged marriage between the Osaka heiress Yoshino Somei and Tokyo’s Kirishima Miyama, the grandson of the Miyama Clan leader, in order to preserve peace. What starts out as little more than an uneasy political arrangement then develops into a tense psychological battle between two equally unpredictable personalities with a constantly shifting power dynamic.

Unlike traditional romances, the series explores the uneasy relationship between its two leads. On one hand, Yoshino is a strong-willed and ruthless young woman who refuses to be manipulated or controlled, despite living in an unfamiliar city, while on the other, Kirishima quickly drops his façade of politeness to reveal his unhinged behavior. Rather than leaning into fluffy affection, the series explores the shifting power between the two as well as their growing mutual respect for one another.

With only 12 episodes, Yakuza Fiancé stands out for its mature, dark romance that subverts seinen expectations. While the series appears to be set up for a season 2, nothing has been announced, and the manga is currently on an indefinite hiatus. That said, the series’ approach to complex, morally gray characters is thrilling and filled with tension, keeping viewers on their toes and constantly guessing what comes next.

Ping Pong the Animation

Some characters from the Ping Pong anime

Ping Pong the Animation came out in April 2014 and follows childhood friends Makoto “Smile” Tsukimoto and Yutaka “Peco” Hoshino. The series takes place in high school as the two navigate their own contrasting attitudes toward table tennis as they face other talented rivals and ever-growing expectations. As it becomes harder and harder to earn a victory, the two must rediscover their passion and embrace their unique strengths rather than trying to conform to the expectations of others.

Attack on Titan (Shingeki no Kyojin) became one of the most-watched anime on Crunchyroll. The story takes place in a world where humanity lives behind massive walls to protect themselves from giant humanoid creatures. What are these creatures called?

AKaiju BTitans CHollows DDemons

✓ Correct! The giant humanoid creatures are called Titans. In the original Japanese, they’re referred to as “Kyojin” (giants). Eren Yeager’s quest to destroy all Titans after they breach Wall Maria became one of the most gripping storylines in anime history.

✗ That answer needs more filler training! The answer is Titans. Kaiju are giant monsters from Japanese cinema like Godzilla, Hollows are the enemy creatures in Bleach, and Demons appear in series like Demon Slayer. In Attack on Titan, these towering humanoid creatures are specifically called Titans.

Studio MAPPA has become one of the most prominent anime studios in recent years, producing several massive hit series. Which of these popular anime was NOT produced by MAPPA?

AJujutsu Kaisen BAttack on Titan: The Final Season CChainsaw Man DDemon Slayer

✓ Correct! Demon Slayer (Kimetsu no Yaiba) is produced by ufotable, not MAPPA. Ufotable’s stunning animation quality — especially the breathtaking fight sequences — became a hallmark of the Demon Slayer franchise. MAPPA produced Jujutsu Kaisen, Attack on Titan: The Final Season, and Chainsaw Man.

✗ That answer needs more filler training! The answer is Demon Slayer. Demon Slayer is animated by studio ufotable, renowned for its gorgeous visual effects. MAPPA has produced Jujutsu Kaisen, took over Attack on Titan: The Final Season from WIT Studio, and animated Chainsaw Man.

Solo Leveling became a massive hit anime in 2024 after being one of the most popular manhwa (Korean comics) in the world. The story follows a weak hunter who gains the unique ability to level up. What is the protagonist’s name?

AJin-Woo Sung BSung Jin-Woo CKim Dokja DYoo Joonghyuk

✓ Correct! Sung Jin-Woo is the protagonist of Solo Leveling. Originally the weakest E-Rank hunter, he gains the power of the mysterious System, allowing him to level up infinitely. His transformation from the “World’s Weakest Hunter” to the most powerful Shadow Monarch captivated millions of readers and viewers.

✗ That answer needs more filler training! The answer is Sung Jin-Woo. Jin-Woo Sung reverses the name order (Korean names place the surname first). Kim Dokja and Yoo Joonghyuk are protagonists from Omniscient Reader’s Viewpoint, another popular Korean series. Sung Jin-Woo is the iconic Shadow Monarch of Solo Leveling.

The Crunchyroll Anime Awards celebrate the best in anime each year. Which anime won Anime of the Year at the 2024 Crunchyroll Anime Awards?

AJujutsu Kaisen Season 2 BFrieren: Beyond Journey’s End COshi no Ko DVinland Saga Season 2

✓ Correct! Frieren: Beyond Journey’s End won Anime of the Year at the 2024 Crunchyroll Anime Awards. This beautifully contemplative series about an elven mage reflecting on mortality and the passage of time after her hero party’s quest ends charmed audiences and critics alike with its unique, introspective storytelling.

✗ That answer needs more filler training! The answer is Frieren: Beyond Journey’s End. While Jujutsu Kaisen Season 2, Oshi no Ko, and Vinland Saga Season 2 were all critically acclaimed, it was Frieren’s meditative exploration of time, memory, and connection that captured the top prize at the 2024 ceremony.

Fullmetal Alchemist: Brotherhood is consistently rated as one of the greatest anime of all time. The story follows two brothers who attempted a forbidden alchemical technique. What taboo did Edward and Alphonse Elric commit?

ACreating gold BHuman transmutation (trying to revive their dead mother) CDestroying a Philosopher’s Stone DKilling a homunculus

✓ Correct! Edward and Alphonse attempted human transmutation to bring their deceased mother back to life. The attempt failed catastrophically — Edward lost his left leg and then sacrificed his right arm to bind Alphonse’s soul to a suit of armor. This event drives the entire series as they search for the Philosopher’s Stone to restore their bodies.

✗ That answer needs more filler training! The answer is human transmutation — specifically, attempting to resurrect their dead mother. In the world of FMA, human transmutation is the ultimate taboo in alchemy. The brothers’ failed attempt cost Edward his limbs and Alphonse his entire body, setting the stage for their epic journey.

Spy x Family became a worldwide phenomenon with its wholesome yet action-packed story of a found family. The father, Loid Forger, is secretly a spy. What is his spy codename?

AAgent Dusk BTwilight CShadow DNightfall

✓ Correct! Loid Forger’s spy codename is Twilight, and he’s considered the top agent of Westalis’s intelligence service, WISE. His mission, Operation Strix, requires him to build a fake family — leading him to adopt the telepathic Anya and marry the assassin Yor, creating one of anime’s most beloved found families.

✗ That answer needs more filler training! The answer is Twilight. Agent Dusk and Shadow are fictional names, while Nightfall is actually the codename of another WISE agent, Fiona Frost, who has a crush on Loid. Twilight is Westalis’s greatest spy and the heart of Spy x Family’s charming story.

Crunchyroll merged with another major anime streaming service to become the dominant platform for anime. Which streaming service was absorbed into Crunchyroll?

ANetflix Anime BFunimation CHIDIVE DAnimeLab

✓ Correct! Funimation was merged into Crunchyroll after Sony’s acquisition of Crunchyroll from AT&T in 2021. The merger consolidated the anime streaming market, bringing Funimation’s massive library of dubbed anime together with Crunchyroll’s simulcast catalog, making Crunchyroll the world’s largest dedicated anime platform.

✗ That answer needs more filler training! The answer is Funimation. Netflix Anime is part of Netflix and operates independently, HIDIVE is Sentai Filmworks’ streaming service, and AnimeLab was a smaller Australian service. Funimation — once Crunchyroll’s biggest rival — was fully absorbed into the Crunchyroll platform.

Hayao Miyazaki and Studio Ghibli are legendary in the anime world. Miyazaki’s final film was released in 2023 and won the Academy Award for Best Animated Feature. What is the title of this film?

ASpirited Away 2 BThe Wind Rises CThe Boy and the Heron DPonyo Returns

✓ Correct! The Boy and the Heron (Kimitachi wa Dō Ikiru ka) was released in 2023 and won the Academy Award for Best Animated Feature in 2024. The deeply personal, surrealist fantasy film was widely considered Miyazaki’s farewell masterpiece, exploring themes of grief, imagination, and the passage between worlds.

✗ That answer needs more filler training! The answer is The Boy and the Heron. Spirited Away 2 and Ponyo Returns don’t exist. The Wind Rises was Miyazaki’s previous “final” film from 2013. The Boy and the Heron marked his true farewell, winning the Oscar and cementing his legacy as anime’s greatest storyteller.
