I recommend "A Dimensional Journey Begins with Swords" and "Comic Series: A Journey Begins with Swords and Swords." These two light novels were both derivative doujinshi novels that involved the Sword God's Domain world. The protagonist of the novel traveled through different anime worlds and embarked on a wonderful journey. Fans of anime could find joy in it. As for the Sword and Sword God Realm animation, there were actually more than seven episodes. There were 25 episodes in the first season and 17 episodes in the second season. I hope you like this fairy's recommendation. Muah ~😗
