Taisaishin is a cardinal god positioned in the direction of the current year in the Chinese Zodiac and is said to define whether actions performed at that angle will be lucky or unlucky.
Taisui Xingjun is also called by the names Yin Yuanshuai and Yin Tianjun and is said to be Yin JiaoWP, son of Emperor Zhou of ShangWP, turned into a god. In the scriptures, he displays many shared traits with Prince Nezha, such as being described as a child and also being born from a mass of flesh.
Yin Jiao was the son of the emperor's first wife, the one who was killed by Daji. In the Investiture of the GodsWP, he was Jiang Ziya's enemy, but in other scriptures, he is on the other side, helping King Wu. By the way, one of his Paopei is the Bell of Fallen Souls, a bell whose sound makes the enemies' souls fall off.
Note: FGO's Servant version of Taisui Xingjun is not confirmed to have any elements from The Investiture of the Gods.
The ribbon he carries is a gift from Meltryllis, originally given to one of the Cons that merged to create him.
Taisui mustn't be awakened (mustn't be unburied). This is his form active as a god of misfortune. An aloof god, an aloof adult. While his appearance fit the "cool beauty" image to perfection, the words he whispers are a bit goofy. He's quite the pessimist. Since he's more strongly aware that he is a punitive god, he believes that humans should bury him back as soon as possible. This form doesn't last for long due to its instability.
Taisui, the mass of flesh, spawned intelligent lifeforms. These lifeforms, the Cons, gathered together and displayed his divinity. The implication here is that they were summoned using Taisui himself as their vessel. An Alter-Ego defined as a fraction of the deity Taisui Xingjun, a piece of his divinity made independent by this Singularity's events. He takes the form of a small boy, and that's his default form as a Servant.
Sea Monster Crisis
Taisui utilizes otherworldly flames to attack his enemies.
He carries with him the Bell of Fallen Souls, a paopei which sound will make the enemies' souls fall off. He can ring it to cause damage, or he can make it grow super-sized and drop it onto his target.

- Shiròu (EX Rank): Taisui is syncretized with Shiròu, a buried flesh monster, known for moving underground in response to Jupiter's revolution. If he's, say, found during a construction, it's believed that those who unearth him or build a house on top of him will suffer terrifying divine punishment. However, other texts mention that eating him doesn't reduce his volume and that eating him grants eternal youth.
