That was really great. Like you say, the visual expression was at full-force for the 25 minutes. I watched it RAW the first time, and it's amazing how well the storyboard and animation convey the characters and situations without the need for understanding any of the dialogue. The short is so transparent in its acting and FX you just can't help but love it.
Props to Yoh Yoshinari and the animators who worked on this! Now waiting until I can see Death Billiards...
