The Takamine family seemed normal at first glance. There was Shigeki, the father, who worked from home and was often distant in his thoughts; Emiko, the mother, who kept the house spotless and was known for her delicious cooking; and then there were the siblings: older sister Akane, a high school student with a penchant for the occult and mystery novels; and younger brother Kenta, who was in elementary school and fascinated with video games and electronics.
