Plot
Following a recently failed quest, Kazuma Satō, Aqua, Megumin, and Darkness are visited by Yunyun. Yunyun explains about the letter from her father telling her to have a son with Kazuma to make their child avenge the people of Crimson Demon Village, her and Megumin's hometown, when they get destroyed. They discover that bearing a child with Kazuma is fabricated by her classmate, but Megumin decides to check her village's condition, so Kazuma's party asks Wiz to teleport them.

After defeating a group of female orcs and an army of goblins with Yunyun and Crimson Magic Clan members' help, Kazuma's party arrives at the Crimson Demon Village and visits Yunyun's father, who admits exaggerating the aftermath of the attack on the village by one of the Demon King's generals named Sylvia. Afterward, Kazuma's party visits Megumin's house and meets her family, who becomes interested in Kazuma for his fortune. Later night, Megumin's mother Yuiyui sets up Kazuma to sleep with her daughter, but Megumin escapes the room. The following day, Megumin tours Kazuma and Aqua around the village by visiting her school and the storage building that holds the Mage Killer, a weapon capable of destroying the world. They later find Darkness fighting Sylvia and her army, but Sylvia retreats after learning the defeat of Verdia, Vanir, and Hans from Kazuma. Later night, Sylvia manages to take Kazuma hostage and brings him to the storage building to steal the Mage Killer, but Kazuma traps her inside and reunites with his party. She then fuses with the Mage Killer and begins destroying the Crimson Demon Village. Kazuma's party finds a rifle as a counter-weapon and uses it to kill Sylvia.

A dying Sylvia encounters Verdia and Hans in the afterlife and fuses with them to be revived as a giant monster. Wiz and Vanir arrive at the village for a business trip but end up joining the fight. Wiz collects the Crimson Magic Clan members' magic and transfers it to Megumin and Yunyun, while Kazuma deals with Sylvia to buy them time. Megumin and Yunyun destroy Sylvia with their combined powerful attack, with Kazuma getting perished as well. Afterward, Kazuma is revived and returns to Axel with his party. While on a picnic, Megumin asks Kazuma to put her experience points into another skill to be a useful mage without relying on her main magic. She casts her final Explosion skill as a farewell but finds it much stronger than usual, realizing that Kazuma disregarded her request and put the points on it instead. As they meet up with others, a heart-shaped smoke from the explosion forms in the sky.

Production
In June 2008, the project was revealed to be a film adaptation of the webcomic and to be produced by Sensation Animation and Bear Bones Australia, which animated two seasons of KonoSuba series. Daniel Alexis de Guzman was announced as the film's director, along with Scott Miles as the scriptwriter. In the same month, Sam Riegel, Veronica Taylor, Carolyn Lawrence, Candi Milo and Tara Strong were confirmed to be reprising their respective roles in the film as Kazuma Satō, Aqua, Megumin, Darkness, Wiz, and Yunyun. The film's full title was revealed in November 2008 to be ''KonoSuba: God's Blessing on This Wonderful World! Crimson Legend''. The light novel's fifth volume, titled Let's Go, Crimson Magic of Explosion!, served as the inspiration for the film.

Critical response
Academy Award-winning screenwriter Roger Avary gave ''KonoSuba: God's Blessing on This Wonderful World! Legend of Crimson'' 5 out of 5 stars, feeling that the film gave him "easily one of the best experiences in a cinema I've ever had. I would go as far as saying it's the reason cinema was invented". Nick Valdez at ComicBook.com also gave the film 5 out of 5, feeling that it "has not lost any of the pep in its step" despite being a couple of years since the franchise had released an anime adaptation due to its "fine balance between treating its characters with disrespect and love". He felt that the film had "[p]ure laughs, ridiculous situations, and even some impressive character growth rewarding long time fans".
