Sheren, Renfa and Shaoren's thought deceased mother.
After her assumed death, her conquered territories broke apart, forcing the remaining Sonken family to serve under Miu's rule.
She appears in the append where one more Kazuto(Gi's route Kazuto is at Gi's castle working normally) appears just after Seki Heki's(Red Cliff's) battle. While the second Kazuto is traveling with Kada, Chousen and Himiko they encouter her camping besides Sai's body, Kada says that her life lifgt is dim but certainly there still some left and revives Sai. After Kazuto's party leaving, Sai wakes up and after confirming that Yenren is alive, asks her to help Renfa and the others. Yenren refuses saying that if they lose to Karin that was the limit for Sonken's Line, after that Sai asks to accompany Yenren wich she permits saying that if Sai becomes a burden she will abbandon her. At the append's story ending, Yenren says that "The continent isn't for Sousou alone. I will show you Son Go's true's power!" and then the Shin Koihime † Musou -Kakumei- Son Go no Kechimyaku is annouced for 2018's summer, making the viewer believe this time she will participate through the storyline.
Yenren first appears watching the sky and catches sight of a falling star near her city. She sends her daughter Sheren to scout it, who brings back Hongou Kazuto with her. When Kazuto is introduced to her, Yenren demands Kazuto proves who he says he is, a person from the future, which he does by using his smart phone and informing her of the 'Yellow turban' rebellion. Yenren than accepts Kazuto's story and decides to re adjust his story to make him out to be a 'messenger of heaven' to improve the moral and position of the Go family. While she intends to use Kazuto's knowledge about future battles, she instructs him to never tell her of the death of significant figures in them. She then commands that Kazuto spread his 'spiritual seed' to the woman of the Go army to strengthen the impression that the Go had the heavens on their side and in exchange she will place him under her protection and feed him, to which he accepts.
Yenren proceeds to lead the Go army to several victories, and even proceeds to have a sexual relationship with Kazuto in order to have more children. She continues to train Sheren in ruling and combat but admits that she's concerned as to if Sheren has the right mentality for Ruling.
