Shigeru Kurumiya

Shigeru Kurumiya is a student at Yūyami High School in the same class as her childhood friend Sumio Haiba.

She was chosen by her old childhood friend, Kirio Imizuka, under the alias of ǝnígmǝ, to attend the fifth e-test.

Kurumiya has the power to see the future (at points) and this ability is what gave Sumio his Dream Diary. Both Sumio and Kurumiya's powers combined make the dream diary.
