Kyogo Shinazugawa

Kyogo Shinazugawa is the biological father of Sanemi and Genya Shinazugawa and is the abusive husband of Shizu Shinazugawa.

Appearance
Kyogo is shown to be an incredibly tall man, compared to Sanemi and Shizu. He has short jet black hair and a large scar over his left cheekbone. He possessed a large and muscular frame.

Kyogo wears a kimono with lavender and black irregular concave hexagons as its pattern, over a white juban.

Personality
Kyogo was a cruel, aggressive, and confrontational man. He would mercilessly beat his wife and kids, using his superior physical might to abuse his much weaker family, all while doing so seemingly without reason. Sanemi's description of him as pathetic implies that Kyogo would always be looking for a way to hurt someone. His harsh and violent personality also put him on the wrong side of people's opinions, which would eventually lead to his death.

Even when his spirit met with Sanemi's in the afterlife, as the latter was close to death, his personality stayed mostly the same, denying Sanemi and Shizu's reunion and forcing him away from the afterlife to regain consciousness. However, he had some proudness in passing on his genetic physical strength to his child, asking him to be proud in being his son as Sanemi would eventually survive the horrific wounds he had suffered in his battles and recover.

Swordsmith Village Arc
Kyogo was married to Shizu and the two would go on to have seven children; Sanemi, Genya, Shuya, Hiroshi, Koto, Teiko, and Sumi. However, Kyogo proved to be an incredibly abusive wife and husband, ruthlessly beating his family. Shuzi would often try to save her children from being hurt by putting herself in the path of the pain, despite being so much smaller than him. His vile nature earned not only the resentment of Sanemi and Genya, but to others as well.

Eventually, Kyogo would meet a violent end by getting stabbed to death, due to other people's resentment of him. His demise would free the Shinazugawa family from his torment.

Sunrise Countdown Arc
Following the battle with Muzan, Sanemi's life began to fade away from suffering numerous severe wounds, and he would reunite with his mother's spirit in the afterlife. When he offered to be with her in Hell, due to Shizu deeming herself unfit to be in Heaven, Kyogo appeared and stopped Sanemi from continuing with his wishes, pushing him away to fall from the afterlife. He told Sanemi to be proud that he is his son, as he's "extra tough". Eventually, Sanemi is able to regain consciousness and survive his wounds, though he curses Kyogo nonetheless.
