The 5 Isekai Anime With Guns Or Firearms

Isekai is a very popular anime genre. It involves a particular setting where the main character is suddenly transported to another world or dimension. This genre gives off a fantasy vibe but some titles are more grounded than others.

In this article we list a few Isekai anime that feature guns, making them more realistic than other titles in the same genre.

You wouldn’t expect guns in a fantasy world but there are edge cases where firearms make sense in the context of the series.

This ranking is based on our opinions and personal experience.

5. Arifureta

A class of high school students is transported to a parallel fantasy world as a group of heroes who must save it from destruction.

All the students are found to possess excellent skills except Nagumo Hajime, who becomes a weak crafter with very low statistics.

One day, while exploring a dungeon, Nagumo falls into a seemingly bottomless abyss. At the bottom, he finds a blonde vampire over three hundred years old, despite appearing much younger, imprisoned there.

The two will fall in love, kicking off a romance in a few episodes. The use of CGI, bad animations, and awkward moments are what make Arifureta mediocre but extremely funny to watch because it’s just bad.

Arifureta displays many huge and over-the-top weapons throughout the entire series. They are fun to see in action but they’re not realistic in any way.

4. The Familiar of Zero

Louise Françoise Le Blanc de La Vallière is a mage who studies at Tristain Academy. She is unable to cast magic spells properly so she is mocked and called Louise the Zero.

One day in class one of Louise’s spells results in an explosion that results in the summoning of a boy named Saito Hiraga from the real world of Japan.

He will be treated like a slave but Louise will quickly realize that Saito is special as he starts to acquire many new abilities that will be helpful throughout the whole show.

Eventually, the fantasy world will suffer geo-political turmoil so, despite the pretty regular premises, the plot will develop in the following seasons. There will be many warlike events during which firearms and war equipment will be shown regularly.

3. The Twelve Kingdoms

Twelve Kingdoms is an anime released in 2002, based on the light novel by Fuyumi Ono.

Yoko Nakajima is a high school student, bored with her life. This will change when a man, who claims to be from another world, breaks into her classroom, kneeling in front of her.

This elegant character, named Keiki, claims to be her servant and guardian, as she would be his queen.

Thus begins Yoko’s adventure into a fantasy world inhabited by all kinds of creatures, while the girl must figure out in a role-playing game what her role is in that realm.

The setting of this anime wouldn’t allow for any guns to appear but the titular Twelve Kingdoms are different dimensions that can communicate with the real world.

The only firearm appearing during the 45 episodes is a Nambu Model 60, a revolver provided to the Japanese police that will be used many times throughout the show.

The Twelve Kingdom is an Isekai with a historical setting and you would enjoy it if you’re a fan of the genre.

2. Saga of Tanya the Evil

Saga of Tanya the Evil is a 12-episode anime based on the light novel written by Carlo Zen. The protagonist of the story is a cynical salaryman who, after firing one of his employees, will be killed by the latter.

Finding himself facing God and not believing in it, the man gets punished by being catapulted into a parallel world at war in the guise of Tanya Degurechaff. He will have to redeem himself here to have his sins forgiven. Thus begins his military career.

A real breath of fresh air for the Isekai genre, that offers a whole new vision in a realistic war scenario and with a protagonist who is anything but heroic.

This is another Isekai set in a warlike scenario so guns and weapons are shown constantly.

Saga of Tanya the Evil has a very interesting premise and you should watch it if you’re looking for an Isekai with an original plot.

1. Gate

Gate is a 12-episode long Isekai that premiered in the summer of 2015.

Youji Itami is an off-duty Japan Self-Defense Forces officer and she’s about to attend a convention in Tokyo when a mysterious portal appears.

Many supernatural creatures and medieval warriors start to come out of the gate and charge through the Japanese capital to the dismay of those present to witness the scene.

Youji is tasked to lead a recon team beyond the gate into the so-called Special Region to learn more about what they are dealing with and attempt to befriend the locals to reach a peaceful solution.

This is done to avoid a war between the two sides of the gate.

Gate is a show with a very militaristic aesthetic so the weapons and the uniforms are quite accurate and very detailed.

If you’re into an Isekai with a plot that has war in the background you should not miss this.
