I Said, I'm Leaving Konoha

Toji cleaned up all traces of the underground laboratory.

After the burns on his body had healed and no one could detect anything unusual, he took a bath, changed clothes, and headed for the Hokage Building.

He carried the last set of research materials on Impure World Reincarnation in his hand. Its contents concerned improving the precision of the Summoning Jutsu. He had previously delayed handing over these materials to Tobirama for two months on the grounds that his "talent was insufficient."
