HP: the Age of Magic of the Uchiha

I, Madara Uchiha, Shura from the ninja world, originally wanted to reunite with my old friends in the pure land, but my soul was torn apart by an unknown force and thrown into another world. When I woke up again, I became a nine-year-old "Flamel" - the most cursed bloodline in the wizarding world. I had huge magic power, but was reduced to a squib due to stagnant meridians. I was regarded as a rare "magic potion material" by the entire wizarding world. The original person committed suicide by taking poison in despair, and I was reborn on his corpse. This world is full of natural energy, but no one knows how to use it. Those wizards waving their wands and chanting incantations seemed to me like children playing. My chakra is almost dry, and the power of the samsara eye has not yet awakened, but I have these natural scarlet eyes and the same bloodline as Otsutsuki! They saw me as prey and wanted to draw my blood, gouge out my eyes, and dismantle me for medicine. As everyone knows—— I am the hunter. When the dark wizard pointed his wand at my throat, when officials from the Ministry of Magic broke into my ancestral home, I just opened these eyes. "Do you want to dance too?" This is a story about Shura recasting reincarnation in the magical world and allowing wizards to see what real power is. "From today on, in the name of Uchiha, I will bring fear to the world."
