Uchiha Itachi-kun died after helping his stupid brother obtain the Mangekyo Sharingan, but what he expected was beyond his expectation - a beam of extremely dazzling light, and then there was an old face in front of him, and he spent two years in a daze. Months later, I gradually understood the structure of this world, and then... At the age of five... I gained the memory of my first life. From then on, Mr. Weasel, the face-paralyzed brother-controller, officially went to the path of no return in the magical world, becoming a ghost and a black-faced brother-controller... (?!)
In short, it is the growth process (= =) of a sinister man with a sinister face, a paralyzed man with a paralyzed face, and then a sinister and sinister man with a paralyzed face and a paralyzed face...
