Summary
Inmany isekai anime,characters don’t just rely on magic and swords to survive. Sometimes, they bring the power of modern weaponry into medieval battles. Whether it’s firearms, battle armor, or high-tech gadgets, these characters are equipped to turn the tide of war with their heavy artillery. This blend of futuristic firepower and fantasy worlds creates an exciting mix of strategy and chaos, where the underdog can easily become the most powerful force on the battlefield.
For instance, inArifureta: From Commonplace to World’s Strongest, Hajime uses his engineering skills toforge deadly weapons,including his twin revolvers, Donner and Schlag. InGate, Itami, an off-duty JSDF officer, brings a whole arsenal to a medieval world, using the Panzerfaust-3 to take down dragons. Even inTrapped in a Dating Sim: The World of Otome Games is Tough for Mobs,Leon uses a powerful suit of armor and a shotgun to fight back against his game world’s social hierarchy.
Combat Agent Six, a glorified henchman of the villainous Kisaragi Corporation, gets booted off Earth to help conquer arandom alien planet.While most locals think he’s throwing around magic, the reality is a lot more high-tech. Decked out in clunky First Gen Power Armor that boosts his strength and camouflages on command, Six bulldozes through enemies with a mix of old and new gear. His arsenal includes a standard-issue pistol, a trusty combat knife, and the brutal R-Buzzsaw, a vibrating bat-sword that slices through armored vehicles like butter.
Thanks to a Miniature Teleporter strapped to his wrist, reinforcements and supplies from Kisaragi arrive at the push of a button. When the going gets tough, Six does not hesitate to whip out an Anti-Material Rifle or even lob an enhanced tear gas grenade.
Ryota Sato found himself thrown into a strange new world after a sudden transportation event. Unfortunately for him, he was weak, with his stats and abilities locked at the lowest possible level. However, Ryota’s unique “Drop Skill, All S” allowed him to collect rare drops from monsters, transforming him into a powerhouse in a place where every item could mean survival. Among his arsenal, Ryota wields a trusty revolver, initially obtained from a defeated Stray monster.
In fact, his high drop stats allow him to receive multiple revolvers, which leads to his ability to dual-wield. Plus, his bullets range from normal to freeze, flame, recovery, homing, restraint, and strength-enhancing varieties, all depending on the monsters he defeats. Even more fascinating, he can combine bullets for unique effects—whether it’s a piercing bullet or an inferno round, Ryota’s shooting skills make him a force to be reckoned with.
Mitsuha Yamano, a high schooler from Japan, unexpectedly falls off a cliff and is transported to a medieval world after gaining the ability to teleport between Earth and this new realm. With her family’s tragic loss and a failed college application, she uses her newfound powers tosecure a future, trading Earth goods for currency and treasures. Skilled with firearms, Mitsuha’s weapon of choice includes the Walther PPS, a small yet effective 9mm pistol, and the Beretta 93R, a machine pistol with a burst-fire mode.
She also uses a .38 caliber revolver for close encounters and carries a submachine gun. Whether it’s a stun gun for non-lethal action or a Gerber folding knife for utility, Mitsuha is always prepared for whatever challenges her unique situation throws her way. With these weapons in hand, she tackles both her mission for wealth acquisition and her survival in the strange new world.
Touya Mochizuki’sreincarnated life kicks offwhen God, feeling a little guilty after accidentally killing him, offers a second shot at life, complete with a souped-up smartphone. Reincarnated into a medieval fantasy world, Touya wastes no time blending magic with modern tech. His real flex, though, comes in the form of Brunhild, a custom-made gunblade forged from dragon horn and metal, combining a six-shooter’s bite with a sword’s edge. Before Brunhild, he dabbled with a revolver modeled after the Remington New Model Army, showing early signs of serious marksmanship skills.
Powered up with enchanted spells, Brunhild lets Touya switch between blasting enemies from a distance and slicing them up close, making him a total nightmare on the battlefield.
Hajime Nagumo was just an average high school otaku until a brutal betrayal hurled him into the abyss ofa fantasy worldcalled Tortus. No longer the meek boy he once was, Hajime mutates into a ruthless warrior armed with brutal ingenuity. With a knack for engineering modern weapons from fantasy resources, he forges an impressive arsenal. His signature sidearms, Donner and Schlag, are revolvers that pack enough punch to tear through divine armor and magical barriers.
Beyond that, Hajime builds the Schlagen, a monstrous anti-materiel rifle, and its bigger, badder sibling, the Schlagen Acht Acht. He scales up even further with the Metzelei minigun and the absurdly overkill Metzelei Disaster Gatling cannon. Throw in rocket launchers like the Orkan and Agni Orkan, a devastating Pile Bunker, a Gatling Pile Bunker, the needle-firing shotgun Alvus, and Hajime becomes a one-man modern military force in a medieval fantasy warzone.
Leon Fou Bartfort, a reincarnated office worker, finds himselftrapped in the worldof an otome game he once played. Now in the body of Leon, a background character in the Holfort Kingdom, survival is a challenge, especially since women hold the power and mobs like him are overlooked. Armed with his vast knowledge of the game, Leon sets out to alter the course of this world by using the cheat item Luxion. One of his primary assets is the powerful battle armor, Arroganz, designed specifically for him by Luxion.
This massive black armor boasts speed, power, and numerous weapons, including drones and missile launchers. Leon’s favorite firearm is a semi-automatic shotgun, often loaded with rubber slugs for human targets and electrified buckshot for monsters. His battlesuit also provides flexible protection, and his Schwert airbike, modified into a hybrid aircraft, merges seamlessly with Arroganz for enhanced combat.
Yōji Itami, an off-duty JSDF officer and hardcore otaku, stumbles into heroism when amysterious portalspits out knights and monsters into Tokyo. After helping fend off the chaos, he gets drafted into a mission to explore the other side, a medieval-style world stuck centuries behind modern Earth. But Itami does not travel light. Packing serious heat, he and his unit unleash the might of modern firepower, from the hard-hitting Howa Type 64 battle rifles to the sleek Minebea P-9 handguns.
Heavy weaponry like the Panzerfaust-3 rocket launcher makes mincemeat of dragons and castle walls alike. Clad in Type II body armor, Itami’s crew becomes a walking nightmare for any sword-wielding army that dares stand in their way, turning ancient battlefields into very one-sided affairs.

Hailing from Japan’s warring states era, he lands among other historical misfits known as Drifters, ready to carve his way through chaos. While Toyohisa prefers old-fashioned swordplay, he packs a brutal ace in his arsenal — a short-barreled Tanegashima, modeled after a sawed-off shotgun, perfect for devastating point-blank shots.
Guns also blaze across this world thanks to figures like Butch Cassidy, who flaunts Colt 1851 Navy revolvers, and soldiers brandishing Ithaca 37 shotguns and Arisaka Type 38 rifles. Oda Nobunaga, ever the innovator, wields his own Tanegashima with deadly flair. On top of that, the anime also mixes in some Gatling Guns, Browning M2s, and Type 92 light machine guns, making the entire thing a mad clash of steel, powder, and lead.
Tanya von Degurechaff once lived the dull life of a salaryman before being reborn as a ruthless girl ina war-torn worldeerily similar to Europe during World War I. Armed with more than just magic, Tanya often carries a Mondragón rifle, a semi-automatic Mexican gun modified to fire magic rounds. Traditional weapons are no stranger either, with Tanya seen using a Luger P08 and Mauser C96, both iconic German pistols. Infantry soldiers around her wield Gewehr 98 rifles, while heavier firepower includes the MG 08 machine gun and brutal 10 cm Kanone 14 field artillery.
The Imperial Army also brings out Stielhandgranate stick grenades, Wechselapparat flamethrowers, and Model 39 “egg” grenades during heated battles. Even Flak 18 cannons, legendary for their deadly precision, show up in the chaos. So, it’s safe to say that in Tanya’s world, it’s not just magic tearing the skies apart, but brutal old-world firepower.
Lugh Tuatha Dé, once the world’s most legendary assassin, finds himself reborn into a noble family of killers, courtesy of a deal with a goddess. Swapping cold modern streets for amagic-rich medieval worlddoes not mean abandoning his old tricks.

His lineup includes everything from standard knives and rifles to heavy-duty cannons capable of erasing armies.
Spells like Gun Summoning and Cannonfire let him unleash volleys of bullets and rounds the size of milk bottles, while the Railgun, packing the punch of a tank cannon, turns battlefield tactics into pure destruction. Powered by fahr stones and deadly precision, Lugh’s modern weaponry gives old-school magic users a very painful crash course in 21st-century warfare.
