Dah-In Hyun, a normal everyday schoolgirl, discovers that she and the other students at Saint Marie have become pawns in a proverbial chess game.

(Seung-Hae even played a violin solo during a choir performance.) His specialty is teleporting, being the fastest among the white chess pieces, and his after school activity is the English club. White Knight.
Suh-Rin "Fabian" Kim
Freshman in middle school, "Matthew" Class. He's the younger brother of Seung-Hae, and he's two years younger than most middle school students, being a child prodigy.

He extremely dislikes glamorous girls (like Hyun-Jin). His hobby is assembling plastic models and his talent is fixing electronics. He has great fighting skills, and his after school club is the Geology club. White chess piece.
Critical reception for Saint Marie was positive, with Mania.com calling the book "confusing" and an "intriguing piece of work".Anime News Network wrote that the first volume was "A diamond in the rough; Saint Marie is as beautiful to look at as it is intriguing to read."
Saint Marie was originally published in the United States by ADV Manga but was put on hold due to budget cuts. ADV has since announced that they have no plans on finishing the series.
