Ah, well, there's a couple of reasons.
Firstly, I wasn't aware of Kill Il, so I thought I was being entirely original.
Secondly, the video has a story that's similar to Kill Bill, except with the lighthearted style of Excel Saga. As in:
Excel's leader repeatedly attempts to assassinate her, so she must receive training and equipment from an old friend ("Nabeshin") to fight back and defeat him.
Basically, in both, you have a blonde exacting revenge on a mysterious and shadowy dictator. But, unlike the Bride, Excel is immortal and fanatically loyal... so her retribution is a bit different.
Thirdly, and probably most importantly, I liked the word play and figured it'd make my vid stand out a little more.
