I recommend "Twelve Movements of the Gods." This novel combined beautiful melodies and fantasy plots from another world. It told the story of a musical genius from Earth singing the songs of the gods in a musical continent full of mysterious power. At the same time,"I Can Summon the Weapon Girl" was also a fantasy novel that combined anime and music. The protagonist had various abilities by summoning the weapon girl and transforming, fighting with others to protect world peace. I hope you like my recommendation. Muah ~
