My Summoned Beast is Uchiha Madara

“What is the Will of Fire? Peace? Bonds? No... it’s my will now.”
Reincarnated into the Naruto world as Itō Hirofumi, the young heir of a forgotten Konoha clan, our protagonist was just trying to stay low… until he accidentally summoned a monster.
Not a beast.
Not a frog.
But Uchiha Madara himself.
With an ancient summoning contract no one remembers, a mysterious system with delayed activation, and Konoha on the verge of chaos, Hirofumi has only one answer for the Shinobi World:
“In the name of Konoha… I, Itō Hirofumi, declare war upon the Five Great Nations!”
