Hinami Fueguchi (笛口 雛実, Fueguchi Hinami) is a ghoul whose parents were killed by ghoul investigators. After the event she began to share strong pseudo-sibling relationships with both Kanekiand Touka. The CCG held insufficient information about Hinami, and therefore failed in eliminating her. She was known as subject Number 745 or Daughterin 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).
As a young teen with a strong resemblance to her late mother, Hinami had short, straight, brown hair, brown eyes, and often wore a hairband decorated with two four-leaf clovers, a common motif for her.
She was identified as the 'Daughter' ghoul when she was wearing her butterfly dress and coat. Therefore, she disguised herself while moving around the 20th ward.
After the time skip, Hinami has grown into a beautiful young woman, with her hair arranged into a bob cut with her fringe parted towards the right side of her face. She first appears in the opening montage wearing a long black hooded cloak. Later on, she wears a plain white shirt, along with a dark-colored long skirt.
