Haunting and vivid imagery. The repetition of the color red mentioned at various points stands out so starkly. Reminds me of a monochrome film or picture with splashes of red drawing the viewer's attention in. Your characterization of Itachi is pitch-perfect. The fact that we find out that he's almost turning thirteen later on, only makes this more disturbing and compelling to read as a POV. I quite liked the scene where he places Shisui's body on the Sandaime's head. It seems like an accuation of sorts, concealed in symbolism. Well done with this.
