He stands for hours, sometimes, looking at the trees. Or, tree, the only one that matters. The tree that has been the cause of so many deaths. Hokuto, Seishirou, and Subaru's mother. And, for that matter, Seishirou's mother, and every Sakurazukamori before her.
He's uncertain why the tree needs death like it does, whether its blood magic, spiritual energy, or just an acquired taste. If foliage can acquire tastes. He wonders if it would die if it wasn't being fed, or if it would just become a normal cherry tree.
But mostly, he just looks.
Cherry blossoms are so pretty.
