I should have expected something from a sadistic little demon girl. The best part in this was how it had such an innocent appearance to it at first with Reiko looking like she was on a simple playground object. The music at the end is fairly haunting too. I love how Reiko has a really good voice that seems to just be what a normal girl would sound like if she was a sadist. That is, a sadist who actually got to live out her fantasies. I liked the animation used at the end with the water, easily the best part.
While fairly brief, single gag submissions are alright with most of us. Let us hope Reiko manages to get all the toys she wants this year. I am now noticing how red is often used in a normal black and white world. It gives off a good sense of madness. Santa is also drawn really well and he better spill the beans soon.
