Summon the Devil

He was once one of the strongest men in the ninja world. Together with his friends, he created a new era in the ninja world! I originally thought that peace would come and ideals would come true, but I didn't expect that the reality was not as beautiful as I thought! In order to realize his dream, he broke up with his friends and took a different path! Uchiha Madara felt that he had found a kid who could barely use it, and then walked into the underworld with peace of mind and waited to be resurrected to practice the Eye of the Moon. However, he did not expect that he would come to a world more dangerous than the ninja world, the demon world! As a demon, Uchiha Madara has lived in the demon world for thousands of years. One day, he was thrown back to the ninja world at the whim of the demon king. His strength was sealed and he became a brat. He was also given a task to increase the demon's reputation in the ninja world. What the hell! PS: It said that it was too troublesome to switch between several accounts, so I moved it to this account. This is an infinite series of imagination, so be careful when consuming it! Then, the update time is uncertain! PPS: It is not easy for the author to write an article. Those who do not accept it can come and leave quietly. This article accepts reasonable suggestions but does not accept malicious comments. PPPS: This article is really a pure spoof, so the character's personality is broken. Please consider whether you want to read it before reading it. Intent: A different kind of encounter may develop in a better direction and change your destiny.
