That is a lost history. Senju Hashirama and Uchiha once teamed up to defend against the enemy. That was a period of time that disappeared, Sarutobi was the darkness and Danzo was the light. It was an unforgettable time and a friendship that was hard to embrace. It was a journey of rising, from a genin to the strongest jounin, a time traveler burned his life. It was a lost memory, buried among the mountains and rivers.
