Dynasty Warriors MV: Unparalleled

Arrows dance and fly in the sky
Unexpectedly they cover up the sunrise on the city wall
是誰 在哭
Who is crying?

“Unparalleled” Lyrics and Translation by
Jay Chou Studio

This is probably old news, but I've only recently heard about Jay Chou, and I'm surprised to find one of his music videos to be a Cosplay MV for Dynasty Warriors Online! He looks so cool as a warrior, doesn’t he? But I wonder if Jay Chou’s cosplaying a character in particular? Do you guys know?
