Naruto: Eating Meat Unlocks the Mangekyo

In Konoha Year 54, following the Nine-Tails’ rampage, the Uchiha Clan was pushed to the brink of survival. Xuan transmigrated as an ordinary Uchiha and activated the Gluttony System. Food became his source of power, and devouring the flesh of ninja beasts made his ocular powers surge. Danzō’s assassins, Fugaku’s suppression, and the Third Hokage’s careful calculations all became stepping stones for his schemes. After surviving an ambush by elite Root operatives, he finally evolved his three-tomoe Sharingan into the Mangekyō Sharingan. Black flames incinerated his foes, and his ocular techniques tore through lies. With blood, Uchiha Xuan established his authority and became the true banner of his clan. “If Konoha sees us as enemies, then let these eyes become their eternal nightmare!” Uchiha Xuan stood atop Hokage Rock, with Susanoo blotting out the sky behind him.
