Isekai is a rare genre of anime that gives its characters a chance to get stronger in another world. While they can’t do much on Earth, characters like Tanya von Degurechaff can be reincarnated into their new worlds with amazing magical abilities. Other characters, like Ghislaine Dedolida from Mushoku Tensei: Jobless Reincarnation, are already walking armies without the need for an after-death boost. No matter if they’re from Earth or the new world, there are some incredibly powerful women in isekai.
