think reverse isekai, instead of a normal dude from earth going to an isekai, someone from a world with magic comes to an earth like (more advanced is fine) world. CN KR or JP is fine. manga is fine too if there's no novel like that. edit: I meant to say magic in a world where everyone else relies on tech rather than magic. the kind where the MC and maybe a very very small group other than him use magic, but everyone else is doing tech shit (maybe mechs?)
I should have been more specific I meant to say magic in a world where everyone else relies on tech rather than magic. the kind where the MC and maybe a very very small group other than him use magic, but everyone else is doing tech shit (maybe mechs?)
http://www.novelupdates.com/series/knights-magic/ = Knights & Magic - i think that's what you're looking for...
Jikuu Mahou de Isekai to Chikyuu wo Ittarikitari mc goes to another world and brings back harem to this one
Awakening would work if you define "magic" broadly. The main character is basically a cultivator with remote sensing, some martial arts and super strength. s Novel is set in contemporary Japan Now, on Kindle Unlimited there are some other novels that might fit and I highly recommend. Then, with the idea of "sufficiently advanced technology is magic" you could try out Perilous Waif (one of my favorites) which is set in a sci-fi setting with personal enhancement running rampart and the main-char got enhancements nobody else got - basically telekinesis and the ability to multitask at an incredibly high level. Depending which "magic" parts you like, it might fit. But again, I just love the book. Another good book is Gods of Blood and Bone (Seeds of Chaos Book 1) which is in a slightly fantasy setting with a "death game" template and the powers some of the players get are magic. Also, due to the nature of the death game they more or less continue the player are more or less forced to continue their life so it might fit for you
Maybe this perhaps http://www.novelupdates.com/series/rokujouma-no-shinryakusha/ Not an isekai but it has magic, over techs, spirit arts, time traveling and a nicely build harem with all members characters are well develoed and MC is not densed, but a badass instead.
