Class 2-D is one of the six classes for second year students at Yagami High School. Due to hostilities between some of their students and even their homeroom teachers, Classes 2-C and 2-D became rivals during the school Sports Festival. Later in the series, some of the 2-D students befriend some of those in Class 2-C and start to hang out with them. 2-D is not shown to really interact with the other four classes in their year. The class' homeroom teacher is Kato.
