It's pretty great. The skill variation going on inside that "game" are a lot, so it's pretty enjoyable to see every people is unique and it's not that much of a repetitive sword swing every time there's a battle scene. The MC personality is great too in my opinion. I loved the MC that different from the generic wimp Japanese character that can't do shit when violence involve. Love to see him pull us along into the story. Too bad it's a short anime, and now I have to suffer wanting to know more on what is about to happen inside that "game".
