Sugar Sugar Rune, Ran to Haiiro no Sekai Recommendations
Both about magic and little girls . Have aslo very similiar feeling with amazing magical world.
They are both magic related and in both of them the heroine is not very popular unless they use magic. Also, both manga revolves around a young heroine (in ran to haiiro no sekai, the heroine can grow up, but she is in fact only ten.)
