Although some of the most popular anime of all time span hundreds of episodes, it’s another kind of delight to start a good series that you can finish on the same day. For viewers with little time or patience who don’t want to risk watching a series that drags on too long without an ending in sight, the most accessible option is single-season anime, as they present a completed story over a few episodes. Especially when many of these animes are short masterpieces that don’t sacrifice quality for quantity.

An anime cour consists of 13 episodes, which is more than enough to tell all kinds of stories. From sports that bring out the most competitive side of viewers and epic journeys with sci-fi elements to thrillers and emotional slice-of-life stories that offer new perspectives on the world, these single-season anime are near-perfect and won’t take too much time to finish.

• Episodes: 13
• Studio: NAZ
• Streaming Platform: Crunchyroll, Prime Video

Taking the best elements from works like Paprika, Inception, and Hannibal, ID:INVADED follows a brilliant detective with a dark past who delves into subconscious worlds that represent the deep minds of heinous criminals to solve real-life mysteries.

91 Days

• Year: 2016
• Episodes: 12
• Studio: Shuka
• Streaming Platform: Apple TV

Although 91 Days may seem like a boring historical drama set during the Prohibition Era, it has deservedly earned its place among the best anime of the last decade for being a true revenge frenzy. The anime follows Avilio, whose family was murdered by the mafia and who is willing to do anything to punish those responsible. Yet, 91 Days unveils a complex web of human relationships that transforms it from a story of betrayal into a profound exploration of whether it’s possible to find meaning in existence through hatred and anger.

Like great anime such as Baccano and Gungrave, 91 Days shares the essence of a Western mafia film. With each episode, the plot becomes increasingly dense and oppressive, filling viewers with the despair of knowing there’s no turning back on Avilio’s revenge and keeping them on the edge of their seats. 91 Days offers refined entertainment and is a mature story perfect for adult fans to binge-watch late at night.

ASTRA LOST IN SPACE

• Year: 2019
• Episodes: 12
• Studio: Lerche
• Streaming Platform: Crunchyroll

Astra Lost In Space is a criminally underrated shōnen anime that starts very similarly to Digimon Adventure but is set in space instead of a digital world. The anime takes place in a technologically advanced future where a group of high school boys and girls, gathered for a school camp, become stranded in outer space and must work together to survive while trying to return to their home planet.

While the fact that it comes from the creator of Sket Dance and Witch Watch suggests viewers can expect plenty of gags, Astra Lost In Space truly shines thanks to its mysteries. With major plot twists and cliffhangers at the end of each episode that leave the audience wanting more, the anime gradually unravels the truth about each character and the reason behind their predicament. Although Astra Lost In Space has a couple of longer episodes, it’s an incredibly entertaining story that’s impossible to stop watching, especially for space lovers.

Death Parade

• Year: 2015
• Episodes: 12
• Studio: Madhouse

Considered one of the best high-stakes anime, Death Parade tells the story of a series of life-or-death games in a mysterious bar called Quindecim, where guests are forced to participate and reveal their true nature to the arbiter in order to be judged. As the guests’ fates are revealed, the themes of death and judgment make Death Parade a much darker story than it initially appears.

The best thing about Death Parade is how it explores the multifaceted nature of humanity in each episode, from the ugliness that emerges when pushed to the limit to the kindness and love that arise in the most hopeless moments, making it a thought-provoking anime. Death Parade has an addictive atmosphere, with a tone that can shift from episode to episode, ranging from depressing to comical, making it easy to watch in one go.

Yuri!!! on Ice is also masterfully crafted on a technical level, with each skating routine feeling dynamic and fluid, delivering viewers a sense of realism on par with an authentic Grand Prix competition. These qualities not only explain why Yuri!!! on Ice deservedly won the award for best anime of the year, but it also explains why fans continue to clamor for a sequel a decade after its premiere.

Instead, the anime is a rather simple slice-of-life following a novelist who takes her niece under her wing after the death of her parents.

From love and struggling against social expectations to cultivating personal relationships, grief, and cohabitation, each episode of Journal with a Witch is filled with metaphors and situations that viewers can easily relate to.

Ping Pong the Animation is a 21st-century anime masterpiece that transcends a simple sports series.

Demonstrating why table tennis is a two-person game, the anime follows two friends, Peco and Smile, as they confront self-deception, overcome anxiety, and break through their limitations.

Ping Pong the Animation focuses on setbacks and growth, delving into the protagonists’ motivations and becoming a perfect coming-of-age story about being passionate about something.
