The year 2000 brings a new opening to Excel Saga, and it's anything but innocent. Excel and Riko, in their skimpy attire, perform a dance that's equal parts cute and provocative. They twist and turn, their bodies swaying in sync, but it's their gaze that's most telling. It's not just about the dance; it's about the promise of something more, something forbidden, something only hinted at in this animated opening. It's a dance that's as much about what's not shown as what is.
