I'm a bit puzzled about the Mc's class in the story. Initially, he was tagged as F class, but after regression, he kept his D class skills. Yet, in Chapter 10-11, they mention him as a "D class." It's a bit unclear with the switching between F and D classes, and the modern martial arts concept and the families, in my opinion isn't really explained properly.
