Hidden Kirito: Kill 99 Classmates at the Beginning

During Kirigakure's graduation ceremony, Zabuza Momochi killed 99 of his classmates and led the demons from hell to seize their homes. While others practice chakra, I practice the soul-eating way. Chase the troops to practice swordsmanship in purgatory, and devour the souls of geniuses to become stronger. At the bridge of the Land of Waves, Hatake Wuwukai came over with his Sharingan, only to see a ghostly figure holding a sword and sneering: "Kakashi, in this fog today, you are the only one allowed to see hell." "Kogakure Demon: Kill 99 classmates at the beginning" ——The ghost is just the title of the book. The one with the knife is the one who cannot even be locked up in hell.
