Yuri(VUBM018) was born on September 27, 2009 in the mob known as the Umbra. His mother was Crystal and Spectra was his father. Genesis(VUBM015), Rengoku(VUBF016) and DIO(VUBM017 were his litter-mates. His parents were the dominant pair and so the four pups were the mina foruc of the mob. Yuri and this three siblings made it to their first year. Yuri started to babysit and take sentry post but he was a bit of a goof around the mob, always wanting to playfight. Yuri is still in the Umbra today.
