This was probably the best in the whole series. Well, I didn't like it that much, but it's still nice. I especially like the different art styles. The CGI looks off, but that's just fine. He probably is a baka. Even a fly can outdo him.
Maybe it could have had music. Well, it's fine the way it is. It's fine for something short, which it is. You should have ninja in the title. That always attracts more people.
