It Starts As A Game

They have a special game, Yaboku and Hiiro, and they're really good at it. Practice makes perfect, after all, and they practice loads. It's really fun, not really because of the blood that sprays in pretty crimson arcs, but because it makes Hiiro smile and father praise them, and those two things make up Yaboku's whole world. Then Yaboku meets Sakura, and everything changes.
