Description
Yoko Yuzuki publicly assumes the role of older sister to middle school student Kanako Yuzuki, concealing her true status as Kanako's biological mother. This deception originated from Kanako's birth following an incestuous relationship between Yoko and her father, Dr. Kōshirō Mimasaka. Kanako stands as the sole heir to her grandfather Yōkō Shibata's fortune, with Noritada Amemiya serving as her legal guardian. Previously a film actress using the stage name Kinuko Minami, Yoko's life is defined by familial secrecy.
After Kanako was pushed onto train tracks by her friend Yoriko Kusumoto, Yoko arranged her transfer from the hospital to Dr. Mimasaka's research facility. Mimasaka, known for wartime experiments involving mechanical replacement of body parts, performed procedures leaving only Kanako's head alive, sustained mechanically within a box. Mimasaka's assistant, Tarō Suzaki, uncovered Kanako's illegitimate claim to the Shibata inheritance. He blackmailed Yoko and staged Kanako's kidnapping to ransom Shibata. Yoko orchestrated Suzaki's murder in response. Severed limbs initially connected to the case were later identified as Kanako's. Amemiya killed Suzaki and fled with the box containing Kanako's living head.
Amemiya was later encountered on a train by writer Shunkō Kubo, who witnessed Kanako's preserved head. Inspired, Kubo pursued similar preservation attempts. Learning of Mimasaka's experiments from Yoriko, Kubo confronted the doctor, who subsequently performed the same mechanical procedure on Kubo, reducing him to a living head in a box. During the final confrontation at Mimasaka's facility, Kubo fatally attacked the doctor, prompting Yoko to kill Kubo to protect Kanako's preserved existence. Tokyo police detective Shutarō Kiba subsequently arrested Yoko for Kubo's murder.
Yoko's actions throughout—maintaining the deception about Kanako's parentage, safeguarding her daughter's inheritance, and enabling Mimasaka's extreme measures to preserve Kanako's life—drive a character arc progressing from manipulation to violence, culminating in her arrest.
