笛口 雛実

Hinami Fueguchi is a ghoul whose parents, Asaki and Ryouko Fueguchi, were killed by ghoul investigators. After the event she began to share strong pseudo-sibling relationships with both Ken Kaneki and Touka Kirishima. The CCG held insufficient information about Hinami, and therefore failed in eliminating her. She was known as subject Number 745 or Daughter in their files. Later, she joined Kaneki's group of ghouls.

After the time skip, she became a member of Aogiri Tree. While her primary duties concern information gathering, she also serves as a strategist and commander when necessary. She became known there under the alias Yotsume (ヨツメ, Yotsume).
