First of all, it’s been some time since I’ve seen Kazuma, Aqua, Megumin, and Darkness in their original non-chibified form, so it’s a rare pleasure to see them in their regular proportions and setting. KonoSuba’s twenty episodes proved you can make an often over-the-top isekai comedy with genuine heart.
If you liked the TV show, you’ll love the movie (as I did), which delivers more of everything. Though it contains roughly a half-cour’s worth of story, the ninety minutes just breeze by. Officially a sequel to KonoSuba 2, we return to Kazuma’s party’s mansion, where notoriously involuntary loner Yunyun has an unusual request: she wants—nay, must—make a baby with Kazuma. She comes to this belief upon receiving a letter from her father, Chief of the Crimson Demon Village.
While that letter turns out to be a work of fiction written by one of her academy classmates, Yunyun is nevertheless compelled to return to her hometown to help fight the forces of the Demon King. Megumin and the others decide to follow her, and rely on Iz to teleport them there.
Unfortunately, they end up far from the village, and in the midst of a stampede of rabidly horny she-orcs (there are no more male orcs) after Kazuma. After Yunyun’s request, this marks the second instance of Kazuma being entangled in romance (for good or ill) which he comes to call his “popular phase.”
What better way to learn more about Megumin than to visit her home? Turns out she’s hardly an anomoly, the town is nothing but overly-dramatic chuuni dressed in cool outfits with an emphasis on reds and blacks. The orcs are scattered by their overwhelming offensive magical power, a quality Megumin also shares with her clan.
Megumin’s parents are each eccentric in their own ways, while her little sister Komekko is adorable as all-get-out. Her family is poor, so the moment her parents smell money on Kazuma (he’s in the process of a 300m-Eris deal with Vanir to sell his memoirs), Kazuma finds himself at the mercy of a mother who wants to pair him with Megumin with all due haste.
To this end, she locks Kazuma and Megumin (sleeping due to a recent Explosion) in a room together. She comes to when he’s about to kiss her after much hand-wringing about how to proceed, and she escapes through the window to spend the night at Yunyun’s, fearing further lecherous advances.
The next day, Megumin shows her friends around the village, including to her and Yunyun’s (very Hogwarts-y) magical academy. We learn that when goblins attacked Komekko, Yunyun sacrificed her amassed skill points to repel the enemy. Because Megumin hesitated, that meant she was able to preserve her points and attain Explosion magic she cultivates to this day.
Megumin finds herself locked in her room with Kazuma again, this time by ice. Kazuma assures her that he won’t do anything, and offers his apologies as well as thanks for all the things she and the others have gone through with and for him.
It’s a very nice heartfelt scene, and Megumin even ends up clinging to Kazuma under the covers, commenting on how he’s really a “wimp” when it comes to making a move. Unfortunately, their tender moment is interrupted by the return of Sylvia, the voluptuous Demon King who leads the attack on the village.
Kazuma managed to scare her and her goblin army off with bluster earlier, but when she learns he’s not really Mitsurugi of the Cursed Sword, she takes him hostage…and Kazuma lets it happen. First, because it’s more proof of his Popular Phase; second, because it’s comfy between Sylvia’s boobs; and third, he has an ax to grind with his comrades regarding his treatment.
Kazuma accompanies Sylvia to the Crimson Demon Village’s underground storage facility, and inadvertently unlocks the chamber where Mage Killer, the one weapon he can’t let a demon king get ahold of, is stored. While he doesn’t intend to make things worse for the village, Kazuma’s so out of it he doesn’t realize punching in the classic cheat code on the Nintendo-style control pad would unlock the weapon.
He manages to lock Sylvia in the chamber, but once she has the Mage Killer and absorbs it into her artificial body, she blows the entire facility to kingdom come, then heads to the village to start blowing it up. Megumin leads Kazuma & Co. to more underground caverns, where they find Japanese carvings that explain the origin of the Crimson Demons, and why they’re so “pretentious yet nerdy”
Turns out their culture was basically created by another Japanese man sent there by the goddesses. He also built the Mage Killer, but also created a countermeasure for it: something he tentatively called “Railgun” that Kazuma previously noticed being used as a backyard clothesline in the village.
When Crimson Demons march out to defend their town, Sylvia engulfs them in an “Ancient Dispel” field that nullifies all of their magical power. They’re “saved” by a suddenly cool and confident Yunyun, finally taking up the mantle of her father the chief and luring Sylvia away.
Turns out she’s acting as a lure to bring Sylvia in firing range of the Railgun. Aqua fills it with magial energy, but it still fails to fire. That’s when Megumin unleashes an Explosion meant to his Sylvia directly, but is instead shunted into the rifle, which her little sister Komekko then fires.
Sylvia is killed, and ends up in the same place as fellow defeated Demon Kings Verdia and Hans. She merges with them an is resurrected into a huge, bizarre four-legged beast. Turns out her old comrades Wiz and Vanir have arrived in the village on an unrelated errand, and join in the fight, but even they are barely able to keep Sylvia at bay.
That’s when Kazuma decides to use his Popular Phase for good; by appealing to Sylvia’s innate need to be loved and wanted by somebody other than her adoring hordes of goblins. Kazuma, his luck boosted by Aqua’s blessings, is that person, and stands before her unarmed and ready to be taken into her arms…or tentacles…or whatever.
I never thought I’d empathize with a Konosuba villain so much, but Sylvia turns out to be one of the most dynamic and sympathetic of Demon Kings KonoSuba has served up. Her feelings, and specifically her romantic longing, isn’t entirely played for jokes, but portrayed as a very human side of her that turns out to be the Achilles Heel Kazuma must betray her heart to exploit.
He succeeds in gaining her trust and becomes one with her as Wiz gathers the magical energy from all of the villagers and transfers it to Megumin and Yunyun, who combine their powers to unleash a gargantuan Explosion beam that, combined with Kazuma breaking her heart, destroys Sylvia and ends the threat to the village for good.
Back home in Axel, Kazuma receives a hero’s welcome, proving his Popular Phase still has a bit left in the tank. While having a picnic with Aqua and Darkness, Megumin asks Kazuma to allow her to learn advanced magic, setting aside her Explosion magic so she can be of greater use to the party.
Kazuma may have long railed against her utter lack of versatility and durability in battle, but spending so much time in close quarters with her and meeting both her family and the villagers who shaped her, Kazuma suddenly isn’t so quick to deprive her of her “Explosiveness”. Whatever he does to her skill card, she’s still able to cast a beautiful Explosion that creates a heart-shaped cloud. And for that, Megumin is happy.
Did Aqua and Darkness get the short end of the stick in this movie? Perhaps, but that meant a lot of great development for Megumin, Kazuma, and their unique bond. They may get on each others nerves at times, but at the end of the day they’ll always be there for each other: Megumin blowing up something that needs blowing up, and Kazuma carrying her home on his back.
It’s quite simply KonoSuba at its absolute best, firing on all cylinders with confidence, comedy, and chemistry. My main gripe with this movie is that it makes me long that much more for KonoSuba 3!
