Synopsis |
Prologue[]
Aqua gets the party chased by a whole horde of Kobolds after she stupidly floods their nest, and gets bitten by one when the party is forced to make a stand. While Darkness is beleaguered to her delight, Kazuma tells Megumin to cast Explosion without worrying about the other two. Although she successfully blows away all of the Kobolds and saves the party, the surrounding farmlands are also ruined, deeming their quest a failure and dooming them to undergo a retraining session.
First Chapter[]
- Beauties and Swimwear for This Midsummer Sea!
- この真夏の海に美女と水着を!
Sent to the summer seaside where strong monsters dwell, Kazuma is delighted by Darkness' bikini while disappointed by Megumin's child swimsuit. Aqua then flees towards him with stinking zombies she had attracted hot on her heels, before she reigns in her disgust at their stench and purifies them. When the party attempts to go back home, they are stopped by Mitsurugi who serves as one of their lecturers. As Aqua who pesters him to play runs off to the sea, Kazuma is delighted to see the other lecturers Wiz and Yunyun approaching in swimsuits, though Megumin gets jealous and kicks sand at Yunyun as well as Darkness.
Second Chapter[]
- Sanctions for This Mr. Mitsu-something!
- このミツなんとかさんに制裁を!
While Mitsurugi is busy persuading Aqua to stop playing, Wiz and Yunyun talk about their reasons for taking the lecturing roles. Mitsurugi who is in charge of lecturing combat skills then tells the party to follow him on a jog, but is complained at by Kazuma for letting Aqua continue playing. Deciding to cut the jog short when Kazuma with low stats cannot keep up, Mitsurugi starts combat training by telling Kazuma and Darkness to attack him. After Darkness who cannot land even a surprise blow is set aside, Kazuma distracts Mitsurugi by lying about Aqua drowning, and successfully lands a blow. Despite Mitsurugi complaining about the dirty trick, under the pressure from Kazuma and the other girls over his flaws, he is forced to declare Kazuma passing the lecture.
Third Chapter[]
- Finally Proper Training with These Crimson Demons!
- この紅魔一族とついにまともな研修を!
Yunyun nervously begins her lecture on magic control, only to get repeatedly interrupted by an irate Megumin. She then demonstrates how to recover magical power through sucking air, but is brought to tears when the girls say it's useless for them, so Kazuma quickly cheers her up before enjoying the sight of Darkness' breasts when she sucks air. Next Yunyun teaches about controlling magic, at which Megumin brings up the disturbing topic of possibly blowing up Axel in case her control over Explosion fails.
Yunyun later brings out some emergency magical stones that change colour when magical power is stored, but when Aqua touches one, she overloads it with so much power that it glows before exploding after Kazuma tosses it into the sea. As Aqua runs into the sea to grab the floating fish killed by the blast, Megumin starts doing the same with the other stones while Yunyun tries to stop her, which results in Aqua getting blasted. After Aqua is rescued by Wiz and Mitsurugi, the dejected Yunyun suggests fishing with magic, though following a demonstration of blasting fish with Fireball, she has to stop Megumin from Exploding all the fish in the sea.
Kazuma subsequently builds a small lagoon with Create Earth so Darkness can chase fishes into it, but the vocabulary of their fishing banter is so lewdly suggestive that Megumin blows the lagoon up with an overloaded magical stone. He then has to stop Aqua who purifies the seawater to kill the fishes from destroying the ecosystem, at which Yunyun cries over the bungled lecture.
Fourth Chapter[]
- Perform Kraken Extermination with This Lich!
- このリッチーとクラーケン退治を!
In her lecture about adventurer attitude, Wiz asks about what is the most important for adventurers, and following Megumin and Darkness' answers of firepower and stamina, she proclaims that it is the bonds between companions, though as Megumin teases Darkness for engaging in childish dreams of adventuring, Kazuma points out the futility of bonding in his party. Moving onto the monster subjugation training, Wiz takes out a small vial from her cleavage to attract monsters, but loses heart at seeing the lack of bonding displayed by Kazuma and his party.
A huge Kraken accordingly emerges out of the sea, which Darkness voluntarily gets captured by, preventing Megumin and Yunyun from using their magic, while Aqua prepares a barbeque. As the Kraken's tentacles slither all over Darkness, Kazuma shows the bonds of their party by using his archery, though he hits Darkness before shooting out one of the Kraken's eyes, and excitedly tries to save her upon hearing that her bikini has come loose.
They then notice a ghost ship is also attracted towards them, yet Aqua is prevented from purifying it because of Wiz. The Kraken then tries to take Darkness away, at which Mitsurugi cuts her free and covers her up, to both her and Kazuma's disappointment. As the undead crew of the ghost ship that was actually attracted by Aqua hops ashore, everybody bonds together in preparation to fight the Kraken and the undead, except for Megumin who releases an uncontrolled Explosion.
Final Chapter[]
- Conclusion for This Good For Nothing Training!
- このろくでもない研修に終焉を!
While Aqua who dived into the sea to escape the Explosion tries looking for the Kraken's legs to replace her ruined barbeque, the others who are miraculously still alive lay around exhausted as they trade barbs. Mitsurugi then allows Aqua to go back much to Kazuma's chagrin, but is horrified when she starts taking out her iration by purifying the sea, which the immobile Megumin is swept into, prompting the infuriated Kazuma to yell that it is the lecturers themselves who need retraining.
