In kiva, Tomoyo Asu and Makoto (the Queen) both love Kurenai Otoya deeply. Kurenai Otoya is Kurenai Wataru's father. Kurenai Otoya only gave birth to Kurenai Wataru with Ye Zhen. Ye Zhen and Kim have too many teeth.
Aso was the first woman that Kurenai Otoya really fell in love with. However, Kurenai Otoya finally had a child with Makoto.
Because, as soon as Shenyang died, Kurenai Wataru tried to change history. So kiva's world should be two parallel worlds, the world before the change and the world after the change.
Before the change, it was obvious that Kurenai Otoya fell in love with Ye Zhen and made her a blood rose. But when Kim found out, Ye Zhen really fell in love with Kurenai Otoya. So, kill Kurenai Otoya. Before that, the Queen really stayed up late and sent Kurenai Wataru to the big villa. Then I gave Taiya to Shimao. But in the end, she lost to Kim, who deprived her of her queen's ability. Among Aso's friends, IXA continues to be used against Fang Youbang. I live with a stranger. His father is also a researcher. This explains why Aso was a member of the Blue Sky Club at the beginning of the first episode.
The past that Kurenai Wataru is trying to change is a bit confusing. I went back once and got a new shape of IXA, which seems to be a burst shape. In order to save yang shen, Kurenai Wataru went back to stop Kurenai Otoya from falling in love with Ye Zhen. Of course, this is futile. Finally, Kurenai Wataru and Kurenai Otoya jointly killed Kiva, who made the king dark.
In this way, it is even more impossible to separate Kurenai Otoya and Makoto. There is still no hope for Yukiko Iwai. Kurenai Wataru brought Kibat II back from the past. Gave it to taiya. However, the priest (one of check mate 4) is not reconciled. Trying to kill Kurenai Wataru. Seems to want to kill Taiya, too. In order to protect his brother, Kurenai Wataru himself became emperor.
After the last fight, Taiya suddenly woke up. And the priest also melted himself into Kiva's body in the dark. The two brothers killed the dark Kiva together. Finally, Aso married Hu Ming. Kurenai Wataru likes who is not pointed out at the end. The overall kiva will be over.
