Seishin High School, one of the top and richest schools in Tokyo, previously had only three floors until one more floor was added in the South Building, especially designed for Class D with only drop-outs in the family as students.

The once called “delinquents”, Class D have changed all because of a transfer student. Now everything around them revolves around Minako Tetsuji, the girl who accepts them for who they are.

But now that she had admitted to herself the feelings she has for Jin Akanishi, will it affect her relationship with everyone? Will she still be helping those around her who need it? And will Jin share mutual feelings or is it just one-sided love for her?

Join Minako and the gang for more trouble, pain and laughter in the Second Arc!
