Karen Ichijo is one of the quieter girls of 2-C, but her appearance is deceiving. She is one of the strongest girls in School Rumble, rivaling both Mikoto Suo and Lala Gonzalez in strength and athleticism. Ichijou's story focuses mainly on the relationship between her and Kyosuke Imadori, and her major contribution to 2-C's victory in the Sports Festival. Ichijou first debuts in Chapter 47 of the manga and episode 14 of the TV series (she had a very minor role in Ep. 7). She appears on the cover of manga Volume 5. She has her own image album at no.6, and is the lead singer for Class 2-C's band.
