Ukina (憂那, Ukina) was the human lover of Yoshimura, and Eto's mother. She worked as a waitress in a cafe, but was secretly an undercover Investigative Journalist chasing the Ghoul organization V. Eventually, she was found out and murdered to safeguard their secrets. Ukina was an attractive young woman of slight build, with a warm demeanor. She wore her sandy blonde hair in a chin-length bob, with short bangs and sidepieces that framed her face. Ukina was a kind, outgoing woman who had a unique sensibility and curiosity. Despite her cheerful persona, she also possessed a sharp intuition which allowed her to see through other people and their facade. During her time with Yoshimura, she showed strong maternal instincts as she forced herself to eat human meat in order for their child to stay alive when she was pregnant. However, according to Eto through reading her mother's journal, Ukina was duplicitous in her undertakings since she apparently became Kuzen's lover to discover the secrets of the Ghoul secret society V. She apparently chose to birth Eto considering her only a necessity to her permanent love affair to Kuzen.
Tokyo Ghoul
Tokyo has become a cruel and merciless city—a place where vicious creatures called “ghouls” exist alongside humans. The citizens of this once great metropolis live in constant fear of these bloodthirsty savages and their thirst for human flesh. However, the greatest threat these ghouls pose is their dangerous ability to masquerade as humans and blend in with society. Based on the best-selling supernatural horror manga by Sui Ishida, Tokyo Ghoul follows Ken Kaneki, a shy, bookish college student, who is instantly drawn to Rize Kamishiro, an avid reader like himself. However, Rize is not exactly who she seems, and this unfortunate meeting pushes Kaneki into the dark depths of the ghouls' inhuman world. In a twist of fate, Kaneki is saved by the enigmatic waitress Touka Kirishima, and thus begins his new, secret life as a half-ghoul/half-human who must find a way to integrate into both societies.

Ken Kaneki has finally come to accept the monstrous, flesh-craving part of himself that he has feared and despised for so long.

As tension between the government and the ghouls continues to rise, the Commission of Counter Ghoul, the government's specialized anti-ghoul agency, has intensified their efforts to completely purge Tokyo of ghouls. This threatens the transient peace of Kaneki's friends and former comrades—the ghouls at the Anteiku coffee shop. Aware of the dangerous situation, Kaneki faces several battles that puts his precious fleeting humanity on the line.

The creation of a special team, known as the Quinx Squad, may provide the CCG with the push they need to exterminate Tokyo's unwanted residents. As humans who have undergone surgery in order to make use of the special abilities of ghouls, they participate in operations to eradicate the dangerous creatures. The leader of this group, Haise Sasaki, is a half-ghoul, half-human who has been trained by famed special class investigator, Kishou Arima. However, there's more to this young man than meets the eye, as unknown memories claw at his mind, slowly reminding him of the person he used to be.
