The Thousand Blades, Yanagi Shina.
In the game, there were six god-level powerhouses who had this title. And Yanagi was one of them, and she was also the youngest among them.
Blade Dancer, Serene Sword, Blade Lotus, Sword Eater, Divine Blade, and Venerable Sun Sword were all the gods that have the title "Thousand Blades."
Blade Dancer was Yanagi, and this name resounded throughout the whole continent when she slew one of the demon pillars. She was just a newly born god, and yet the power she possessed and her eccentric personality terrified a lot of people.
Despite just reaching godhood, Yanagi quickly improved her abilities to the point that she surpassed those of the gods that were protecting the Hebrei Kingdom.
