Blending in the crowdas a background character, he is the strongest boss of a shadow organization fighting to fulfill his fantasies.

Hardly any anime fans have yet to watchThe Eminence in Shadow. It is one of the most interesting takes on the isekai genre, with a detailed world setting and lore. Some can compare it toOne Punch Man, where the protagonist is not the center of attention but the other characters surrounding him. As the strongest character, he uses magic and slime to create protective clothing, swords, and crowbars for combat. He also has the magical power to “nuke” an enemy by splitting an atom. Moreover, his control over magic is so exceptional that he can even use it if the surrounding magic is suppressed. Plus, he is very calculative in his battles and can even use his body to close in on an enemy to launch a decisive counterattack.

Enraged, God sends him toa war-ridden worldas an orphaned little girl named Tanya Degurechaff. He (now she) takes up the challenge and, initially being a cold, calculating person, dominates the battlefield despite God’s efforts to make it difficult for her.

With a fresh and unique concept,The Saga of Tanya the Eviloffers more than it showcases on the surface. The story explores Tanya’s journey as she progresses in her military career and helps the Empire become undefeatable. Hence, it is an interesting and engaging plot that will glue the viewers to the screen as they anticipate the next episode. Although magic exists in the new world, it is integrated with modern weapons and tools. Hence, Tanya uses the same tools to help fight the war. She uses a rifle for short- and long-distance enemies and a box-like tool to fly around for aerial warfare. Moreover, the entire anime holds up solely due to its highly likable protagonist with her strategic mind and expert decision-making skills. It has only one season and a movie with season 2 in the works.

However, he deals a bad hand when he becomes the “Shield Hero.” The other people become the heroes of a sword, bow, and spear. His fate worsens when he is wrongly accused of SA by the cunning Malty Melromarc, who backstabs him. Eventually, he is expelled from the kingdom and starts his journey of strengthening himself and regaining his reputation.

Despite being stuck to only using a shield, Naofumi learns about the truth of his role and uncovers the secret of the ‘Monster Waves.’ He also explores his skills and knows how to use his shield for defense and offense. He can continually upgrade his shield by feeding it remnants of the monsters, which helps him unlock new skills and functions.

Eventually, Naofumi grows to become overpowered, which the other heroes can no longer refuse to deny. The fourth season ofThe Rising Of The Shield Herois due for release soon.

As he enters the mysterious world, he makes powerful allies and prepares himself to vow revenge on the Goddess.

Like Cid Kagenou fromThe Eminence In Shadow, Makoto Misumi has also undergone some training in combat and archery skills. As a result, it makes him exceptionally powerful from the get-go. With his love for archery, he uses a bow and arrow made from magic with different elements. He also uses creativity to use the fireball spell as a Gatling gun. In season 2, he learns to use his mana to envelope himself with a shield. With that, he became unparalleled in close combat as well. Still, his most potent strike is when he pours his mana into his magical arrow, which can decimate an entire area.

It allows him to create powerful modern weaponry with the help of materials found in the deepest regions of the labyrinth.

Taking it as a fresh opportunity to live a new life of freedom, he accepts the request and reincarnates as Lugh Tuatha Dé. From a young age, he starts honing his skills as an assassin by incorporating his previous world knowledge and Magic.

Lugh is one of the few genius protagonists who is well-versed in many subjects when he was working as an assassin and relatedexperiences from his previous life. It is handy as he navigates his new life while tackling the mission of growing strong enough to defeat the hero. He creatively uses Magic by combining his skills and knowledge to create modern weaponry like sniper rifles, bombs, canons, and ‘Rod from God.’ The last item is an overpowered weapon similar to a nuke involving a rod launched from space to hit a designated target. Moreover, he is proficient in close combat due to his previous life experience as the best assassin. In such fights, he relies on daggers and metal gloves. The second season ofThe World’s Finest Assassinis underway, and there is no release date yet.

Unable to accept his ill fate, he goes on an adventure to find the item he spent his money on. After seeing and claiming the item as his own, he must navigate the unforgiving society.

Regarding weapons, Leon relies entirely on items purchased in his previous life. He gains ownership over the AI assistant Luxion, who oversees futuristic robots, airships, and a base. Leon uses a giant robot to fight with other robots and uses the airship to get around. Although he has little combat experience, his unique items make up for it due to its difference in power from the existing items in the world. There is also a little foreshadowing where Luxion tells Leon that Leon has the blood of the ancient humans, who developed all the technology he inherited. Throughout the series, he uses his gaming knowledge to gain other items and help the original protagonist get her powers. The second season of the series is currently underway.

Sentouin Roku-gou is a chief operative of the villainous Kisaragi Corporation. He is assigned to infiltrate the kingdom of Grace to help alter the world’s fate. Although he believes himself overpowered, the reality is far from his expectations. Moreover, he has to perform minor evil deeds to gain points and power in his combat suit. The anime explores his journey of infiltrating the kingdom and helping them win against the Demon Lord’s army.

Although the anime has a simple premise, it makes up for the hilarious personality and skills of Sentouin Roku-gou. With a focus on comedy, his combat skills entirely depend on the combat suit he brings with him from the future. However, he goes on to find certain artifacts and weapons with the help of his futuristic robot companion, Alice. He can use his suit to note down weapons or items he needs, and the HQ provides them. As a result, he can use most items from the future in a fantasy setting.

Fans of Gundam and giant robot fights will loveKnights & Magicfor its unique premise. It explores the story of Tsubasa Kurata, a programmer and an otaku who meets an untimely death and reincarnates into a medieval world.

As a programmer, Tsubasa can navigate the intricate workings of Magic and mechs to create unique Silhouette Knights. Although he helps the kingdom protect themselves with his Knights, his ultimate goal is to build the best mech no one has ever seen before.

Knights & Magicdoes an exemplary job by showing Tsubasa’s journey in building his mech. UnlikeArifuretaandIn Another World With My Smartphone, Tsubasa is more knowledgeable in the intricate workings of giant robots. As an otaku, he spent his free time building models of fighter robots, from which most of his ideas stem. His skills as a programmer also help him ‘program’ magic, as he wants to help the mechs work the way he wishes. As a result, he can make the existing mech perform beyond its capabilities. He also uses it to create new machines that perform much better and faster than older robots. Although the anime has decent CGI fights, fans love it more for the building phase of the mechs.

He also finds the two of them already familiar with the new world, who help him learn the ropes. As they traverse the new world, they must complete quests, gain experience, and grow stronger for unknown reasons.

I’m Standing on a Million Livesis one of the few isekai anime where the protagonist and the other characters can traverse the modern and fantasy worlds. The new world also shares some concepts of a video game where one can revive in 30 seconds as long as one party member is alive. When it comes to combat, Yuusuke struggles to fight due to his class restrictions, as he is a villager. However, it doesn’t stop him from engaging in fights, as he will use anything apart from weapons to defeat his enemies. Throughout his journey, he used a frying pan, a sickle, a wooden stick, and other random items to fight. Still, there is much to be desired, since he does not have the relevant stats for combat. Hence, he must rely on special non-combat items and his wits to shine.
