While there are no improvement for the world of Knights and Magic, the introduction to Gundam wasn't too bad for someone like me who never watched/read it. Ernesti seems to stay similar although the addition of family for theme makes him more grounded. As for the MC, he quickly is shown to be a genius and while I don't fear him becoming a Gary Stu, I wonder how he will grow in this world.
Overall, I recommend reading it.
