Shihō Kimizuki/Relationships

Mirai Kimizuki
Kimizuki Shihō's younger sister and whom he loves deeply, Shihō has taken care of her since she became afflicted by the Apocalypse Virus in 2012; however, caring for Mirai was very hard for Kimizuki as he had to carry her due to the Virus inhibiting her ability to move on her own, to avoid both the Horsemen of John and the vampires. Even when Mirai told his friends she wanted to die and they tried to get Shiho to kill her, he refused.
