Toki no Kizuna: Sekigahara Kitan is a visual novel on PSP developed by Otomate and published by Idea Factory and can be considered a prequel to Hakuouki. It was released in Japan in 2012. It follows an Oni girl named Yukina Suzumori who is the head of the Suzumori Oni clan and the servant guardian of Yase-Hime, the head of the council of the ten Oni Clans.
"It’s a year after Toyotomi Hideyoshi died (1599), and the human world is once more falling into war. The head of the ten oni clans, Yase-hime, becomes worried about the future of the oni people. She travels to each of the ten clans, now scattered across the land, and asks them to retreat from human contact. On the night that they obey her and all gather in the Yase village, she’s kidnapped and put into a deep sleep. The oni heroine, Suzumori Yukina, is the head of the Suzumori household and was also strong enough to be the ninja guardian of Yase-hime. She’s serious and respects the old ways, and has a hawk companion. Throughout the game, she must decide whether to look for a cure for her princess Yase-hime in the human world, in spite of Yase-hime’s request not to deal with humans."
Yase-Hime is the head of the Council of the Oni clans and has the ability to have visions of the future. She sees Yukina as her little sister. After seeing a vision, she assembles the council and warns them not to affiliate with humans anymore as a terrible war was about to start which was the Sekigahara War. Following the meeting, she gets attacked by a hooded figure who poisons her, making her succumb to a coma.
