Yen Press teased an announcement that would “BLOW. YOUR. MIND.” and that announcement turned out to be the acquisition for the Konosuba: An Explosion on This Wonderful World spinoff series. The Konosuba spinoff is set to receive its first release on June 18, 2019.
Yen Press summarizes the spinoff as follows:
In Konosuba: An Explosion On This Wonderful World!, everyone’s favorite explosion-obsessed spellcaster Megumin and her Crimson Magic Clan are back in this spinoff of the hit comedy!
The parent story, Konosuba: God’s Blessing on this Wonderful World, received an anime adaptation that aired in January 2016 which spanned 10 episodes. A second season aired in January 2017 and also spanned for 10 episodes. In addition to the original light novels, there is also a manga adaptation which are both licensed by Yen Press for publication in North America.
MyAnimeList.net describes the parent story of Konosuba as follows:
After dying a laughable and pathetic death on his way back from buying a game, high school student and recluse Kazuma Satou finds himself sitting before a beautiful but obnoxious goddess named Aqua. She provides the NEET with two options: continue on to heaven or reincarnate in every gamer’s dream—a real fantasy world! Choosing to start a new life, Kazuma is quickly tasked with defeating a Demon King who is terrorizing villages. But before he goes, he can choose one item of any kind to aid him in his quest, and the future hero selects Aqua. But Kazuma has made a grave mistake—Aqua is completely useless!
Unfortunately, their troubles don’t end here; it turns out that living in such a world is far different from how it plays out in a game. Instead of going on a thrilling adventure, the duo must first work to pay for their living expenses. Indeed, their misfortunes have only just begun!
