Hidden thrusts?

                                                                        

In Saiyuki Gaiden vol.2 Tenpou said about Ritoten that his family was in the Earth and that’s why in Tenkai he is discriminated. 
Tenpou said also that he guesses that Ritoten has created the ways that have request the figure of the god of war.
So Ritoten has created Nataku to grow his position. How Ritoten could created the ways? 
Maybe thanks his family that is in the Earth? Maybe his family makes a pact with demons? 
Maybe his family is joined with the race of demons?
So we can think that there is a descent of the family of Ritoten?
We don’t know yet what will be the destiny of Ritoten. If he should die his connection with the Gaiden’s characters should finished? 
And now there isn’t any connection? Maybe Ritoten could be connected with Kenyu/Nii/Ukoku? Maybe Ukoku could be a half god? 
Maybe also Genjo Sanzo is an half god too? Maybe is that the similarity of which Koumyou Sanzo was talking about in the Ukoku’s Burial?
Is Ukoku an human being? If he should be an human being as he looks it’s strange his connection with those ravens that always surrounding him.
Is Ukoku a demon? If he should be a demon he must wearing some limiters but seems that he hasn’t them. 
And why he should hide his demoniac nature within the castle of Houtou in which there are only demons? 
Besides the female doctor that works with Nii talks about him saying that he is a mere human being and Dokugakuji in Against the Stream said to Sanzo that the only human being within the castle is Nii.
So I thought that probably Ukoku could has a connection with gods.
In the Kamisama’s saga the Ukoku’s pupil said many times the word “god”. The same name “Kamisama” means that. 
He said that his master always saying that “all lives are god’s toys”.
Then, when Kamisama is dying, he said to Sanzo party that the player is Ukoku. When he meets Nii the last time said that he knew that he was just one of Ukoku’s toys…
So if all the lives are god’s toys and the player is Ukoku = Ukoku is a god?
When Ukoku met for the first time child Kamisama didn’t want take the child with him but after asks to him “Do you believe in god?” We don’t know the Kamisama’s answer but maybe this answer was important because Ukoku took him as his pupil. Before the death, Kamisama, asks to Ukoku: “Does “god” exist?” and Ukoku responds “He probably doesn’t exist”.
The same name “Kamisama” is important. Kamisama said that he wanted became like his sensei but that is impossible. 
When Kinkaku and Ginkaku guessed that Kamisama was a god called him “Kamisama”. 
Maybe Kamisama hasn’t never said them his real name because with the name “Kamisama” he should be similar to his sensei.
Maybe Ukoku isn’t a pure god but has in his veins the blood of demons too (maybe the demons that was joined with the family of Ritoten?)
I have thought that also Genjo Sanzo could be an half god (with the blood of demons and gods but he hasn’t any connection with the Ritoten’s family) because:
In Saiyuki 1 the spider woman looking at Sanzo’s eyes said: “You have beautiful eyes. Such a waste for use on a human.”
In Saiyuki 2 Sanzo remembers his past when he lived to the Kinzan’s temple. A day a bear enters in the temple and the warriors monks aren’t able to move away it. So Koryu intervenes and manages to move away the bear. In this occasion the monks talk about Koryu and say that his eyes are like those of shura or rasetsu.
In the evening Shuei comes in the chamber of Koryu and looking at him said that: “This afternoon everybody was calling you like a shura or rasetsu but…I think you look like something else” and he thinks: “God-like gold strands of hair, deep dark purple eyes…the full moon is there to act like the light that’s given out as an aura…”. So Shuei sees in Koryu the imagine of a god.
Also in Sanzo’s Burial a monk remembers the same words of the monks of Kinzan’s temple.
In the last part of this Burial the Sanbutsushin said: “Let’s just see…what this ‘enlightened devil’ is capable of…”
Maybe it is no accident that Sanzo is the protector of the Maten and Seiten Kyoumon.
In Saiyuki 9 Ukoku met for the first time Koryu and maybe he remembers the time in the Ukoku’s Burial in which Koumyou Sanzo said that Kenyu and Koryu are similar. So Ukoku said: “Oh, I see…you are both saint and devil.”
Another hypothesis about Ukoku is…is that he is dead. And someone (a god maybe Ritoten?) controls his body. 
I have thought that because:
Ukoku is always near ravens that are symbol of death.
Ukoku is the protector of Muten kyoumon that controls the death.
In Even a Worm 15 Gato said to Hazel that Ukoku is like a dead.
In Even a Worm 16 Genjo Sanzo didn’t feels the presence neither of a human being or a demon. Maybe because Ukoku is a god or Ukoku is dead?
