I'm more impressed with his use of magic. Min maxing what you can do in the most efficient way always looks the coolest over the biggest flashy techniques. They have their moments but nothing says competent like super fine control.Not a bad story. Reminds me a lot of that, except the stupidly-high level thing... well there's also the temporary isekai aspect(goes to another world, then returns for good), but really, its the "'legendary' adventure with 3 girls" aspect that reminds me the most. This story is also more grounded, with Igami teaching them about the rawness of life and death and things of that nature; the linked story doesn't have that same weight(even though it is just as dangerous).
