Oh, yeah, I watched it every episode, too. But still...somehow it didn't click. ^^;;; I even remember the episode where actual Chiriko shows up; they show him in silhouette and I was like, "oh, he looks like the OP there!" I think it was somewhere in there that I put things together, haha.

(I believe it was Amiboshi, btw. It was for what happened to him after he was discovered that Suboshi wanted revenge.)
