Leader of the Ashen Wolves. Lives under the Officers Academy in an underground society, which is called Abyss. He's also currently the only known bearer of the Crest of Aubin. Described as being of crass speech but extremely devoted to the protection of Abyssians, even when it is not easy to tell, it is clear that Yuri is quite sharp-tongued and reserved, dryly teasing his fellow classmates. However, he is also shown to be kind under his rough exterior, caring deeply for the safety of Abyss.
