Yuri is slightly below average in height and moderately fit, doing his best to remain unremarkable in appearance so that he can fit in anywhere he might need to go. He wears his black hair somewhat short and loose (but not shaggy) and remains clean-shaven most of the time.

His purple (violet) eyes are rather distinctive but easily concealed by contact lenses.

He's friendly, personable and well-mannered, gets along with just about everyone.

He spent 16 years working for an unnamed government alphabet agency before a corporate raider offered him a lot of money to work for them. He gave them 4 good years before retiring.
