KonoSuba

Development

Akatsuki grew up reading fantasy novels like Record of Lodoss War, Slayers, and Sorcerous Stabber Orphen, with Lodoss War being the first book he ever picked up and a major spark for his love of the genre. He also enjoys the game Kantai Collection and has said that his pen name came to him while playing it. Before he wrote KonoSuba, he entered a draft in a light novel contest but was told he needed to improve his basic writing skills.

He kept practicing and eventually decided to take writing more seriously. His goal was to create a series that stood out from typical light novels, one that would deliberately defy common fantasy genre expectations. The fantasy elements in KonoSuba came from video games like Wizardry and Final Fantasy, as well as tabletop role-playing games.

When building the characters, Akatsuki made sure each one had unique quirks, no matter how small, pointing to Aqua’s fascination with odd rocks as an example. Some characters ended up different from his original plans; Mitsurugi, for instance, was supposed to be a rival to Kazuma’s party but instead turned into another goofy, eccentric figure. Akatsuki has said that his favorite supporting characters are Dust and Vanir. He first found out about the anime adaptation in January 2015.

Anime

At the time, he was living in Fukui Prefecture and was supposed to travel to Tokyo for a meeting, but his house was buried in snow, so he couldn’t go and learned about the anime over the phone. Koichi Kikuta and Momoka Komatsu were the chief animation directors for the series, with Kikuta handling odd-numbered episodes and Komatsu handling even-numbered ones. Komatsu’s character designs stayed close to the light novel art and made the characters look more attractive, while Kikuta took inspiration from children’s shows like Pokémon because he felt KonoSuba’s story had a similar feel.

Publication

The original web novel for KonoSuba was posted by Akatsuki, writing as Jitakukeibihei, on the Shōsetsuka ni Narō site between December 20, 2012, and October 21, 2013. After it was picked up for print publication, the web version was taken down on December 10, 2013.

Light novels

Akatsuki also wrote a side story centered on Wiz and Vanir. A light novel version, featuring art by Kurone Mishima, came out under Kadokawa Shoten's Kadokawa Sneaker Bunko label from October 1, 2013, to May 1, 2020. Starting with the sixth volume, the light novel plot differs a lot from the web novel, and the characters' ages were also adjusted. The seventeenth and final volume includes an afterword hinting at possible future content, specifically teasing what might appear in the "After Story" spin-offs.

A spin-off light novel series focused on Megumin, also written by Akatsuki and illustrated by Mishima, is set one year before the main story. It ran from July 1, 2014, to June 1, 2015, across three volumes. A two-volume sequel followed, released on December 28, 2016, and March 1, 2019.

Another spin-off, this one featuring Vanir, came out on April 1, 2016. A third spin-off series, written by Hirukuma with illustrations by Uihime Hagure and centered on the character Dust, started publication on August 1, 2017. A collection of short stories, titled KonoSuba: God's Blessing on this Wonderful World!

Reception

By January 2018, it topped BookWalker's worldwide ranking of the top 50 best-selling digital manga and light novels.

Print numbers grew to 6.5 million by February 2019 and reached a total circulation of 10 million by November 2021. The series also won BookWalker's 2016 Grand Prix Award. Critic Andy Hanley of UK Anime Network praised the first novel's comedy, noting how it played off a "tired genre," and found the cast appealing due to their distinct traits, though he criticized the volume's short length.

The anime adaptation also garnered recognition. In 2016, it placed tenth for best TV anime in the Newtype 2015–16 Awards and was runner-up for Best Comedy at the Crunchyroll Anime Awards 2016, losing to Haven't You Heard?

I'm Sakamoto. In 2019, Funimation's Decade of Anime poll, based on fan votes across categories, awarded KonoSuba "Isekai Series of the Decade." The anime received positive reviews for its comedy, its parody of the isekai genre, and its faithful adaptation of the light novels. Reviewing early episodes, Anime News Network's Theron Martin called the second episode "the funniest episode of anime I have seen since Monthly Girls' Nozaki-kun aired" and praised the musical score. Voice acting was also highlighted: Nick Creamer of ANN commended Sora Amamiya and Rie Takahashi for the energy they brought to Aqua and Megumin, while Martin noted Jun Fukushima's dry tone as Kazuma added to the humor.

Critical response

The film Legend of Crimson was reviewed by Daryl Harding of Crunchyroll News, who praised its story and comedy, stating the "classic humor of (the TV series) translates well to a film runtime." However, he criticized the film for looking "not too different than the TV series," despite "more effects placed over the animation during scenes of explosive magic."
