Shiba Yuu/History and Plot

==Anime==
===Episode 74===
Ran Jyuusan is asleep on the boat that is on the way to the Ran Clan's main residence but she is having a nightmare. When Shi Ryuuki shakes her awake, she draw her sword on him. After she settles down, she sits with him and tells him the story of how she met the love of her life.
As soon as Jyuusan finds her mother murdered, Shiba Jun walks into the room. When she sees him, she moves in front of her mother's corpse and stares at Jin for three days. He stares back at her, not moving until he sees her getting tired. When she says she'll only trust him if he "gives her his eyes", he gouged out one of his eyes without hesitation. Before he could do the same to the other, she stops him.
It was revealed later on that Shiba Yuu had sent his son, Jin, to assassinate Jyuusan since she witnessed the murder of her mother but Jin couldn't do it and was subsequently thrown out of the house. He was in love with Jyuusan's mother (who was his cousin and childhood friend) who used to love him back. But after she became one of the concubines of Ran Setsuna's father, she fell out of love Yuu. Bitter that she didn't return his feelings anymore, he murdered her.
Sometime later, he attempted to rape Jyuusan but was stopped by Jin. Jin murdered him to protect her, even though he knew that patricide was punishable by death.

===Volume 15===
When Ran Shuuei goes to the Department of the Cave of Immortals to see Uu Uu about sending him to the Hidden Palace of the Hyou Clan, he meets up with Jin there who is also going there. Though, he is going there for a separate reason. When Shuuei asks Uu Uu why someone so suspicious was in his office, Uu Uu is confused as to why he's saying he's suspicious since he possesses a blue aura and a light indigo aura. Shuuei is surprised that Uu Uu noticed this. He then thinks about how Jin looks different from others in the Shiba Clan and why his father was so distant to him. It was because he was the product of one of his father's illicit encounters. Specifically, a product of his father's illicit encounter with a woman from the Hyou Clan passing by on the road.
