I, Itachi Uchiha, Turned Black on the Eve of the Genocide

It was just a little little devil who died in the Blue Star battlefield, but was accidentally reborn into Uchiha Itachi. Kakashi's inner demon: You are a waste for killing Rin and Obito. You are a waste of air when you are alive, and a waste of land when you are dead! Naruto's inner demon: The whole world rejects you, the whole world hates you, just die, there is no point in living! Uchiha Fugaku's inner demon: What happened to Uchiha today was caused by you. You can't save the family or the clan! Danzo's inner demon: He knows you are better than Hiruzen Sarutobi, but he won't let you become Hokage. Go ahead and get your Hokage back! Obito's inner demon: Lin was killed by you! You can obviously reincarnate her, why don't you do it? Senju Hashirama's inner demon: You are a hypocrite! Do whatever it takes to achieve your goal! You can even commit suicide, what else is there that you can't do? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
