Kagami Yagami

As the second oldest sibling in the Yagami family, this classmate of Sasami is best known for her perpetually drowsy nature. Though she possesses a remarkably plain and unassuming appearance, she remains a key figure among the Yagami sisters. Her character is defined by a constant state of lethargy, often appearing as if she is on the verge of falling asleep during her daily school activities.
