shi jin (fate)

Accompanies Eliza The Nine-tattooed Dragon as her draconic three-sectioned staff. He was a Servant summoned with Lancer Elizabeth Bathory, but they were defeated in battle. Shi Jin decided to impart his Spirit Origin to Elizabeth, fusing them together into the Nine-Tattoo Dragon Eliza.

Shi Jin is one of the 108 Stars of Destiny from Water Margin, specifically the Minute Star (#23 of the 36 Heavenly Stars), known as "Nine-Tattoo Dragon" for the many dragon tattoos on his body. Elizabeth Bathory herself is affiliated with dragons due to her family using the fang of a dragon as its family crest, so those aspects are fused together into their Pretender version.
