Personality & CharacteristicsEdit
As a government official, works extremely hard, despite his advanced age.
After requesting leave from the Hyou clan from Ruka, they have agreed to "meet again at Twilight".
The Blue Immortal remarks that Uu Uu does not have much time left and asks him if he would want to change something in his past. However, while Uu Uu does think that he has many things that he would want to see changed, he refuses. This refusal seems to make the Blue Immortal very happy and the Immortal proceeds to say that "they" will not help him as they will only watch from the background as usual. Uu Uu along with Ruka worked hard to keep the 'Gate' from opening after the destruction of the sacred artifacts. Uu Uu weakened himself by using up his life to eradicate the locust plague. Right after, he was coldly killed by a fanatical official of the Cave of Immortals.
