Hikari Shinomiya

Kikoru's mother and Isao's wife. Deceased at the start of the story. Former leader of the 2nd Division. She was equipped with one of the Defense Force's strongest weapons, "Numbers 4," and was highly popular, being praised as a Valkyrie. She lost her life in a series of disasters caused by Kaiju No. 6. Hikari's death has greatly impacted both Kikoru and Isao's pride as Defense Force members, but not much has been said about her influence or Hikari herself.
