[HEY, LOOK AT ME, I'M A TARD WHO DOESN'T READ THE FORUM RULES]

They are unrelated except for the outlook of some of the characters (like Sakura and Syaoran from CCS and Mokona from Magic Knight Rayearth and some from xxxholic.)

obviously Jap anime. I think Animes are way better than american cartoons (especially with wut they air this days..it makes me sick). If the Jap anime is subbed in English then im happy.

i wanted to find the missing gap too but with no luck at all. I am beginning to wonder if they just decided to to leave the gap there. (hope not)
