text: Soichiro seems to be a sword expert: he prefers to use the sword instead of his wife's Luger P08 pistol and has trained with Saeko Busujima's father. Later he entrusts Saeko with a katana made with military-grade steel at an industrial weapons factory. When the zombies breach the estate, he and his troops fight them off. He tells Takashi Komuro to go save Rei's parents, and entrusts Kouta Hirano with protecting Saya. While the Takagis and the rest of the estate survivors fight against the horde, Soichiro comments that they are proud of their daughter and the friends she has made.
  Yuriko Takagi
  is Saya's mother. She worked in New York City as a Wall Street stock broker until she met and married Soichiro Takagi. The Takagi family fortune rose significantly due to her business connections. When the zombies breach the estate, she gives Saya her Luger P08 pistol, and then proceeds to assist her husband in fighting the horde.
  Miku Yuuki
  is a second-year Fujimi High student, who schoolmate Morita says is one of the sexiest girls in school. She sides with Koichi Shido when he takes over the bus, and participates in their debauchery. When Yamada questions Shido, Yuuki suggests they kick him off the bus. She also helps Shido enter the Takagi estate by flirting with one of the guards, but is forced to leave after Shido is expelled from the estate. She later appears alongside Shido at the entrance to Shintoko Third Elementary School.
