Manga question

has anyone heard of a series called clover?

 

Yes. It's by CLAMP.

Sue is a Four Leaf Clover, the only one in existence. Ran is a Three Leaf, one of two. Gingetsu is Two Leaf and Oruha is One Leaf. Each book tells a different tale of these tragic children, backtracking from when Kazuhiko takes Sue to Fairy Park to when Ran becomes Gingetsu's ward.
