Yes, Shugo Chara. You should watch the anime, it's an anime that is actually good with fillers. <3 Although it's better to watch it in high quality, the episodes I find don't usually turn out that way. D: Only about two or three, but for the episodes that are high quality, it's just so easy to be amazed. Even if the episodes aren't high quality, the anime still looks really beautiful.
I've been meaning to try Fairy Tail, but lately I've been obsessed with Shugo Chara. ; I'll be sure to get to it eventually. Along with Kanon, Haruhi, Sailor Moon...*rambles on about the different animes she promised to watch*
