A magical cartoon I saw a long time ago.

Chinese name: Magic Partner, Magic J×R, English name: (Magic j×R) is a girl cartoon drawn by Korean cartoonist kine.

I remember this is also a cartoon I read in the bookstore a long time ago. At the beginning, I talked about two young heroes, one with short curly hair and the other with long hair. Later, when they grew up, they went to the human world to complete the upgrade task, and as a result, they met a girl who knew kung fu. . . Unfortunately, I only read one book, and the rest of the comics were not found. Good story, I like it very much. ?

This is the cover of an English cartoon.
