A note on Kou, Kou, and Kou ^_-:
*Ahem* It should be noted that Kou is the first name for all of the Lights. They are not related in any way, they are just best friends. Someone asked Naoko-sensei this question at the SDCC, and that was the answer.

Comments:

Ya know what? Seiya used to be my favorite Starlight/Three Light. But after watching more of Stars, I've decided that I like Yaten more. [grin] Oh yeah. IMO, Usagi would have been better off with him rather than cape-boy. And that's all I've got to say about that.
