Yoko Tsukiyo (Moonlight sisters father)

Yoko Tsukiyo was 10 when his parents were killed by a unknown demon ( Yumi, she wants to end a families bloodline to be ranked higher), he was welcomed in a new life meeting Jigoro Kuwajima and he became Yoko's master. He trained him to be a Hashira and raised him to be respectful and strong. When he was sent off as a Hashira, he met Kozuki Tsukiyo, they both fell in love and got married 24 years old. When he was 26 years old, his oldest daughter Mitsuki Tsukiyo was born, at 33 years old Yuzuki Tsukiyo was born, and at 39 his younger daughter Luna Tsukiyo was born. He was worried that if his injuries weren't healed he wouldn't be able to go on missions and protect his family. All he was able to do was get his children out of the burning house and then something fell in front of the door and he was trapped and couldn't climb out to help Kozuki because he was still injured. He was very happy that he could see his children all grown up during the afterlife. He was proud that his daughter Luna could avenge their family and his parents.
