God Slaying Emperor Blade is a sword that belongs to Cocytus.


Originally the God Slaying Emperor Blade belonged to Warrior Takemikazuchi but later gifted to his creation Cocytus before he retired from YGGDRASIL.


The blade is an odachi with the length exceeding 180cm.


Among the twenty-one weapons Cocytus has in his possession, it is the sharpest. Its edge is so sharp that it can cleave through magical armor or even physical enhancement. It has very high durability even being used to cut down the lizardmen's hardest armor.[1]


  • Cocytus only unsheathes this weapon to those he has the greatest respect for.
  • This weapon looks very different in both the manga and anime. It looks like a normal katana.
  • In the English publication of the Light Novel, the God Slaying Emperor Blade name was translated as Imperial Sword Zashin.
