Yuri is the leader of the Ashen Wolves. He was a student of the Officers Academy, but was expelled due to circumstances, and moved to live in the Abyss. Underneath his crude speech, it can be vaguely seen that he holds a strong desire to protect the residents of Abyss.
The name "Yuri" exists in many languages and has differing origins. Yuri is the Russian and Ukrainian form of George. In Hebrew, Yuri or Uri means "the light of God". It is also the Japanese vocabulary word for lily.
