Crimson Magic Clan members Megumin and Yunyun are at the top of their class, but they still have a lot to learn. Yunyun's begun learning advanced magic, but Megumin has gone down a different path-the path of explosion magic! Despite being warned of its limited usefulness, Megumin believes explosion magic is the way for her to become a great, voluptuous wizard, and she won't be convinced otherwise!

The ultimate magic... explosion! Pushing aside her hometown's teachings, Megumin, the genius mage of Crimson Magic Village, sets her sights on the raw destructive power of explosion magic. But when she arrives home with Yunyun to find Komekko, her little sister, surrounded by monsters, she's faced with a tough choice. Will she give up on explosion magic and spend her precious skill points on advanced magic in order to save her sister? And what has that strange cat got to do with all this?

Megumin has arrived in Axel, and she's got a devil to defeat! Rumors abound of a powerful Arch-priest well versed in exorcism, and our resident Explosion expert intends to track her down! Meanwhile, Yunyun renews her desperate search for friends, but she's getting nowhere fast...It's the end of the beginning for these Crimson Magic adventurers as Konosuba: An Explosion on This Wonderful World comes to a fiery conclusion!

Megumin is off to Arcanletia, the city of water, hot springs...and the Axis Church! With no money and no connections, she soon finds herself helping its members in their efforts to secure new recruits! Along the way, she'll discover just how strange the Axis Church and its followers truly are...

Leaving Arcanletia and the Axis Church behind, Megumin and Yunyun hop on a wagon bound for Axel, where Megumin's role model awaits. It's going to be an even rougher ride than they expected, however, when monsters assault them at every turn! Is this just bad luck, or is there something more sinister at play...?

Someone's stolen Megumin's heart! Enamored with a supercool masked man from the Silver-Haired Thief Brigade and captivated by the group's outlaw lifestyle, the Arch-wizard resolves to form her own crew of bandits to support her newfound idols. Unfortunately, her "thieves" are problem children all around: a girl who can't make friends, a super-overpowered princess, and a priestess with questionable morals. Can the explosion-obsessed leader of this band of unlikely burglars pull things together when real trouble strikes?

After being transported to another world, Kazuma is joined by his allies Aqua the goddess, Megumin the magician, and Darkness the crusader. As they conduct more missions to fulfill quests, like purifying a lake while fending off monstrous alligators, they also progress as adventurers, receiving rewards from successful outings and skilling up. But one fateful day, one of the Demon King's terrifying dullahan generals approaches their sleepy beginner city. And somehow, Megumin gets his attention straight away, or should we say, earns his wrath... What are they going to do?!
