Definitely Powerpuff Girls Z! Yeah, I know their eyes don't look like アニメ eyes, but their based of the American Powerpuff Girls, so their eyes look similar! Japanese poster to prove its Japanese:
No matter what my お気に入り will always be Card Captor Sakura :) . This アニメ gave me so many happy memories and it never grows old for me . My 秒 choice would be Puella Magi Madoka Magica and a third choice would be Shugo Chara .
