Alter Ego-class welfare Servant in [[Fate/Grand Order]]. A Chinese mythological god said to be the deified form of "Tai Sui":https://en.wikipedia.org/wiki/Tai_Sui, a planet that mirrors Jupiter. The [[Chinese zodiac]] is based on divisions of Jupiter's orbital cycle rather than the Sun's in the Western zodiac, so Taisui is able to define whether any given year will be lucky or unlucky by using the 12 zodiac signs multiplied by the five Chinese elements (fire, earth, metal, water, and wood), or 60 divisions.

Taisui has a child form voiced by [[Minami Omi]], and an adult form voiced by [[Kawanishi Kengo]].
