Persona: Tsumi to Batsu
Yuri is a member of the Reapers, a group working under Yakumo Kusaka of the Nymphéa Group. Yuri participates in the group's collection of Personas by use of the Grim Reaper, which steals Personas from innocent people, leaving them with something akin to Apathy Syndrome. On top of that, Yuri is actually one of the lead developers of the Schwarz System, alongside Yakumo Kusaka and B.B.. Taking after his father, Doctor Nicholai, from Megami Ibunroku Persona.

Yuri has a very expressive and delinquent-like personality. He is rather carefree and enjoys fighting. Despite his seemingly childish appearance, Yuri is a scientist of some sort, and is devoted to both Yakumo and his father.

Yuri's role in the story is relatively small, he acts as an obstacle for Kazumi and his friends, and participates in the final battle in the other Sumaru City. During the fight, much like the other remaining members of the Reapers, the Black Book's hold on Yuri begins to mutate him, spikes and veins protruding from his body, and the back of his head doubling in length. His self consciousness slowly waning. Yuri, along with Rhea, are defeated by Narui and Keito after Rinne and J-F weaken the Schwarz System, and Narui and Keito awaken to their ultimate Personas. Yuri and Rhea collapse, and speak their final words alluding to Yakumo's even greater strength, still believing in Yakumo's ideals. After this, Yuri is not shown again.

Yuri's motivation throughout the story has been to avenge his father's treatment by SEBEC and Takahisa Kandori, having been used and then discarded when he outlived his usefulness. Yuri somehow seeks revenge and to further develop his father's research in aiding Yakumo and B.B. develop the Schwarz system. Although Nicholai is not referred to by name in the manga, the author Naotsugu Matsueda later confirms in notes that Yuri was meant to be a secret tie-in to the first game, and that his father was Dr Nicholai. He also explains that the research used to develop the Schwarz System is then used to develop the Joker Separation Machine after being sold to a Nanjo Group agent, as seen in the manga's epilogue.
