Shiroe is a young man who finds himself trapped in the game Elder Tale, just after it released it’s latest expansion. Winding up there alongside thousands of others on the same server, Shiroe has no way of escaping...and even death only causes him to reincarnate.
After the betrayal, he ends up dropped into an even more dangerous part of the dungeon they were exploring ...and gets his arm eaten by a giant monster. After that, Hajime resolves to become the strongest and make his way back to his world, no matter who he has to step on to get there.
5 KonoSuba. KonoSuba follows the story of Kazuma Satou who dies an early death and is reincarnated in a different world full of all sorts of crazy things like magic and Demon Kings. With the help of Aqua, Kazuma aims to defeat the Demon King, but he isn't quite cut out for the job.
It’s an addicting watch, and unsurprisingly it’s getting a second season in 2020. But in the meantime, here’s fifteen anime to try out while people wait.
3 Death March kara Hajimaru Isekai Kyousoukyoku. Death March follows the story of Ichirou Suzuki, a guy who spends most of his time debugging games. Surprisingly, when he goes to sleep, he's pulled into the world of the games that he often works on.
Tsubasa Kurata is a coder who dies being hit by a car after buying his favorite mecha. He’s reincarnated in another world as Ernesti Echevalier, or “Eru”, a young man born to a family of nobles. Thanks to his skill with engineering in the old world, he becomes skilled not just in the new world’s magic, but in building “Knights”, the giant robots used as a primary form of military might in this new world. Knight’s and Magic gives us a classic overpowered protagonist, as Eru shoots this world from “realistic” robots that are just giant hunks of metal to laser-firing Gundams in a matter of years.
Drifters just barely fits the definition of an isekai anime. While most series, including Reincarnated as a Slime, tend to take someone who was unimportant on our world and make them into worldbeaters on another world, Drifters takes people who were already great in our world and sets them against impossible odds on another.
