Entertaining and definitely put a smile on my face!
Animation is smooth, and sound effects are well used.
I would recommend trying to keep the length of these animations down to under 5 minutes or so, as stick figure animation starts to (in my opinion) lose its appeal if it drags own for more than a few minutes. i don't really like the use of text either; some stick shorts use grunts or just keep the characters silent, but if you wish to continue with text be my guest.
While the animation is fluid and entertaining, the story is admittedly a bit boring and childish (though, perhaps you were going for a child-like feel, i dunno.) I would recommend putting out more flashy fight scenes than animations based on a story, especially because, in my mind, stick figures just don't seem compatible with more complex story stuff. Even if this was a sort of parody of anime's (which I got from the opening segment), I feel your talents would be better spent making short and bad@$$ fighting scenes than longer, more childish stuff like this.
