Sima Yi (Reines)

Sima Yi (Reines) is a Rider-class Pseudo-Servant appearing in the game *Fate/Grand Order*. She is summoned into the body of Reines El-Melloi Archisorte, and possesses the spirit of Sima Yi, a famous general and strategist from the Three Kingdoms period of China. Reines, the original vessel, is the head of the El-Melloi faction of the Clock Tower’s Twelve Houses, but relinquished her position to Lord El-Melloi II. She has a mischievous and malicious personality, enjoying the misfortune of others, yet she can be a reliable ally when needed. Sima Yi, on the other hand, is a calm and strategic military leader, whose persona is not fully merged with Reines, resulting in glimpses of his own personality. Their Noble Phantasm is “Unspoken Formation,” which exposes opponents' weaknesses. Reines also wields the El-Melloi family's Supreme Mystic Code, "Volumen Hydrargyrum", capable of transforming into various forms and enhancing her abilities, including becoming a mercury maid. Their summoning is a chain reaction triggered by Kongming's Noble Phantasm, "Chu Shi Biao". Overall, Sima Yi (Reines) is a unique Servant who combines intellect, mischief, and considerable power.
