A must-see

People change, and no one is completely unchanging. The protagonist chooses the ancient sword as a weapon because of the influence of his previous life, and because of the change in the environment, he gives up his swordsmanship and goes out of his own way. That's what I wanted to write. In the first chapter, the protagonist uses an ancient sword. I also use some sword skills. Although a bit of a discord in front. But I don't want to change. If, you can't fit in. Then please click on the horn fork again. Thank you. Also, in addition to a world with a complete system. I'll add some other anime to some of the chapters. These anime will be mixed together by the author-kun. So, if you can't adapt, forget it. And these plus into the anime. It will usually be anomalous. Of course, individual cases are not excluded.
