Seiken no Blacksmith, Sword Art Online: Alicization Recommendations
Just a heads up, it is good to watch each other. They have the same manga artist that I believe the adaptation takes upon it. So if you liked Alicization's artstyle and wanted more, definitely look at Sacred Blacksmith too. There are other similar points like Knights and medieval town setting, wielding a powerful sword, saving the girl, and facing the enemy together. I also like their names, Cecily and Alice, cute girl's name, similar feel XD Both are pretty girl knights I would watch. The guys are cool and step into the fray when needed.
