by The hit isekai comedy KonoSuba: God’s Blessing on This Wonderful World! is celebrating the 10th anniversary of its television anime with a special streaming campaign on ABEMA. To mark the milestone, the Japanese streaming platform launched the “KonoSuba: God’s Blessing on This Wonderful World! ABEMA Channel” on October 9, 2026, offering fans a chance to revisit the series’ main anime seasons, its Megumin-focused spin-off, and its theatrical film.
The five-day event ran through October 13, bringing together all 33 episodes from the first three seasons of the TV anime, all 12 episodes of the spin-off KonoSuba: An Explosion on This Wonderful World!, and the movie KonoSuba: God’s Blessing on This Wonderful World! Legend of Crimson. ABEMA also announced that each title would remain available to watch for free for two weeks after its broadcast or streaming presentation.
The campaign forms part of the broader KADOKAWA/ABEMA Anniversary Anime Selection, a special initiative celebrating KADOKAWA anime properties reaching important anniversaries in 2026.
For longtime fans, the event offers a chance to revisit Kazuma and his unpredictable party. New viewers can also use the available episodes to discover why the franchise has become one of the best-known comedy series in the isekai genre.

What Is KonoSuba About?
KonoSuba: God’s Blessing on This Wonderful World! is an isekai comedy based on the light novel series written by Natsume Akatsuki and illustrated by Kurone Mishima.
The story follows Kazuma Satou, a video game-loving shut-in who dies unexpectedly and finds himself facing a choice about what to do next. He encounters Aqua, a goddess who offers him the opportunity to be reborn in another world. Instead of choosing a conventional advantage, Kazuma decides to bring Aqua along with him.
His new life quickly becomes more chaotic than he expects. Kazuma and Aqua are joined by Megumin, an eccentric young mage obsessed with powerful Explosion magic, and Darkness, a crusader whose unusual personality makes her a source of constant trouble.
Together, the four form an adventuring party that is rarely short of problems. They accept quests, battle monsters, encounter powerful enemies, and try to earn enough money to survive. Yet their greatest difficulties often come from their own personalities and questionable decisions rather than from the dangers of the fantasy world.
This mix of fantasy adventure, parody, slapstick comedy, and character-driven humor is central to the series’ appeal. Rather than presenting a perfect hero and a dependable group of companions, KonoSuba follows a team whose members are powerful in their own ways but frequently create problems for one another.
All Three TV Anime Seasons Are Included
ABEMA’s anniversary lineup includes all 33 episodes from the first three seasons of KonoSuba. This makes the campaign a useful opportunity for viewers who want to revisit the main story or catch up before the upcoming fourth season.
Season 1: Kazuma’s Unfortunate New Life
The first season introduces Kazuma, Aqua, Megumin, and Darkness as they begin their lives as adventurers.
Kazuma hopes to enjoy a more exciting existence in a fantasy world, but his plans are quickly complicated by Aqua’s behavior, Megumin’s obsession with Explosion magic, and Darkness’s unusual approach to combat. The group’s financial struggles and frequent misadventures become a major source of comedy.
The season establishes the relationships and comedic style that define the franchise. It also introduces the fantasy setting, its adventurer guild, and the challenges Kazuma’s party must face.
Season 2: More Quests, More Chaos
The second season continues the group’s adventures, expanding the story with new quests, unusual characters, and increasingly ridiculous situations.
Kazuma and his companions face new challenges while continuing to struggle with money, responsibility, and their own shortcomings. Their relationships become more familiar to viewers, and the series builds on the humor established in the first season.
For fans, Season 2 offers more of the unpredictable interactions that make the party so entertaining.
Season 3: The Party’s Adventures Continue
The third season continues the story of Kazuma and his companions as their adventures bring them into contact with new situations and characters.
Although the group occasionally demonstrates genuine courage and teamwork, their personalities remain a constant source of trouble. Kazuma’s pragmatic attitude, Aqua’s dramatic behavior, Megumin’s single-minded dedication to Explosion magic, and Darkness’s peculiar interests continue to drive much of the comedy.
Watching all three seasons together allows fans to follow the party’s development and enjoy the recurring jokes, relationships, and running gags that connect the series.
The 33-episode lineup also gives new viewers a straightforward way to experience the main TV anime before exploring its spin-off and movie.
KonoSuba: An Explosion on This Wonderful World! Focuses on Megumin
The anniversary campaign also includes KonoSuba: An Explosion on This Wonderful World!, a 12-episode spin-off centered on Megumin.
Unlike the main series, which primarily follows Kazuma and his party, the spin-off explores Megumin’s earlier life and her fascination with Explosion magic. It follows her experiences before the events of the main story and offers a closer look at the background behind her distinctive personality.
Megumin belongs to the Crimson Magic Clan, a group known for its powerful magical abilities and dramatic mannerisms. From an early age, she becomes fascinated with Explosion magic, a spell with enormous destructive power that also comes with a significant limitation: after casting it, she loses the ability to move and must recover.
Despite this drawback, Megumin remains determined to master the spell. Her single-minded dedication becomes one of her most recognizable character traits in the main series.
The spin-off provides additional context for her ambitions, relationships, and magical training. It is especially appealing to viewers who enjoy Megumin’s comedic personality and want to learn more about her life before meeting Kazuma, Aqua, and Darkness.
For newcomers, the spin-off is best appreciated after becoming familiar with Megumin through the main anime, although its earlier timeline offers a different perspective on the character.
The Movie: Legend of Crimson Is Also Part of the Lineup
ABEMA’s special programming also includes the theatrical film KonoSuba: God’s Blessing on This Wonderful World! Legend of Crimson.
The film continues the adventures of Kazuma’s party and places particular emphasis on Megumin’s homeland and the Crimson Magic Clan. The group travels to the village where Megumin and Yunyun grew up, leading to new revelations, dangerous encounters, and the franchise’s familiar combination of action and absurd comedy.
The movie expands the world of the TV series while giving Megumin’s background and connections greater importance. It also delivers the large-scale magical confrontations that are difficult to present on the same scale in an ordinary episode.
For viewers following the main series, the film is an important part of the anime lineup. It is generally best watched after Season 2 and before Season 3 to follow the story in release order.
By including the movie alongside all three TV seasons and the Megumin spin-off, ABEMA’s campaign brings together the franchise’s main animated releases in one anniversary promotion.
KonoSuba Season 4 Is Scheduled for 2027
The anniversary celebrations arrive as the franchise prepares for its next major television installment. Season 4 of KonoSuba is scheduled to air in 2027. The broadcast year and key production details were announced in July 2026 as part of the anime’s 10th-anniversary project.
The upcoming season will feature a production team that includes:
- Chief director: Takaomi Kanasaki
- Director: Manabu Kurihara
- Series composition: Makoto Uezu
- Character design: Koichi Kikuta
- Animation production: ENGI
The main voice cast is also set to return, including Jun Fukushima as Kazuma, Sora Amamiya as Aqua, Rie Takahashi as Megumin, and Ai Kayano as Darkness. Additional returning cast members have also been announced.
The move to a new animation production company is one of the notable changes for the fourth season. However, the announced key staff and returning cast provide continuity with the franchise’s established creative identity.
The cited announcement has not confirmed a specific premiere date within 2027. Fans should therefore treat 2027 as the announced broadcast year rather than assuming a particular month or season.
KADOKAWA and ABEMA’s Anniversary Anime Selection
The KonoSuba channel is part of the wider KADOKAWA/ABEMA Anniversary Anime Selection, which highlights anime properties reaching significant anniversaries in 2026.
The initiative includes a range of works, with special channels or free marathon streams arranged for selected titles. Other announced properties include Steins; Gate, Re: Zero − Starting Life in Another World, The Melancholy of Haruhi Suzumiya, and Bungo Stray Dogs. The wider anniversary selection also features works such as The Familiar of Zero, Aria the Scarlet Ammo, I Don’t Have Many Friends, Joker Game, and Pompo the Cinephile.
The program gives viewers a chance to revisit older anime and discover titles they may have missed when they originally aired. It also highlights the continued popularity of established franchises, many of which remain relevant through sequels, spin-offs, anniversary events, and streaming availability.
For KonoSuba, the timing is particularly appropriate. Its 10th anniversary celebrates a decade since the television anime first introduced Kazuma and his chaotic party to viewers in 2016.
Why KonoSuba’s 10th Anniversary Matters
A decade after its anime debut, KonoSuba remains recognizable for its unusual approach to the isekai genre.
Many isekai stories focus on protagonists who become powerful in another world and gradually build successful lives. KonoSuba uses that familiar setup as the foundation for comedy. Kazuma may be the protagonist, but he is often forced to deal with companions whose abilities are impressive and whose behavior is deeply impractical.
Aqua is a goddess but frequently causes trouble. Megumin can unleash devastating magic but insists on using a spell that leaves her unable to move afterward. Darkness is a skilled crusader, yet her unusual preferences complicate even simple encounters. Kazuma’s own selfish and sarcastic personality adds another layer of chaos.
The result is a fantasy adventure where victory is not always the most important outcome. Many of the series’ most memorable moments come from arguments, misunderstandings, failed plans, and the party’s inability to behave like a conventional team.
The anime’s continued popularity has also allowed the franchise to expand beyond its original three seasons. The Megumin spin-off explores an important character in greater depth, the movie offers a larger-scale story, and the upcoming fourth season promises another chapter in the party’s adventures.
The anniversary streaming campaign celebrates that history by bringing the major animated installments together for fans to revisit.
KonoSuba: God’s Blessing on This Wonderful World! marked its TV anime’s 10th anniversary in 2026 with a special ABEMA streaming campaign featuring all 33 episodes from Seasons 1–3, the 12-episode Megumin spin-off, and the movie Legend of Crimson.
The dedicated channel ran from October 9 to October 13, 2026, and each title was announced as remaining free to watch for two weeks after its stream. Since the scheduled channel event has ended, viewers should check ABEMA’s individual program pages to confirm whether a title is still available at no cost.
The celebration also arrives ahead of Season 4, which is scheduled for 2027 and will be animated by ENGI under a newly announced production team.
Whether viewers are returning for Kazuma’s sarcastic humor, Aqua’s chaotic behavior, Megumin’s explosive magic, or Darkness’s unpredictable personality, the anniversary offers a reminder of why the series has remained a favorite among fans of fantasy comedy.
With the next season on the way, the 10th-anniversary celebration is both a look back at the franchise’s history and a chance to prepare for the party’s next adventure.
