Under major revision, the following is the revised text:
Haruno Sakura has a secret. She will enter a dungeon (another world) every other week to practice for many years to improve her abilities.
He also bound his teammates Uchiha Sasuke and Uzumaki Naruto before the night of genocide.
After the night of genocide, Uchiha Sasuke, who didn't know how old he was in his shell and had seen through everything, fell into deep thought: Is my brother really stupid? Why does he want me to hate him?
Uzumaki Naruto, who has been accompanied and taught by his friends since childhood, said that he would always accompany him, while Haruno Sakura couldn't help laughing next to him.
The years are quiet and good, and Class Seven will last forever.
