this is going to be long

Nina was a average school girl until the 2 sourcers (Itchy and Zero) came to planet earth to find the crystal pearl but instead they found friendship.now they are starting a whole new year.And this year will be a year that they will never forget.

Its been 10 years since zero and iichi left and went back to the magic world. 22 year old Nina still remembers the day she swallowed the crystal pearl and the time she met zero and iichi. Will her normal life in the human world change when she meets an old friend?
