Astaroth (アスタロト Asutaroto), also known as The King of Rot (腐の王 Kusa no Ō), is one of the Eight Demon Kings. In a bid to return Rin Okumura back to Gehenna, he possessed Reiji Shiratori, the leader of a delinquent gang.
Astaroth looks like a possessed human with the additional features of goat-like spiral horns, longer and sharper nails, canine like teeth, red eyes, a Demon tail, and a longer tongue.
In his full form, Astaroth's appearance becomes much likely a stereotypical Demon (with goat like characteristics like having rounded horns and standing on two goat-like lower limbs). He becomes bigger, his skin turns a dark red colour, possesses claws, his horns become much bigger, his eyes turn completely red, and his teeth become battered. This form only appears in the anime.
True Cross Academy arcAstaroth, possessing the student Reiji Shiratori, appears to Rin and goads the young man into a fight. His companions (who are unaware of Reiji's possession) immobilize and suppress Rin. Despite his companions’ uneasiness, the Demon-possessed boy draws a knife and threatens to mutilate Rin's face. Fearing for his life, Rin subconciously releases an aura of blue flames for the first time, proving to the Demon that he was the son of Satan whom he sought. However, before he is able to bring the son of Satan back to Gehenna, Father Fujimoto appears and swiftly defeats the Demon via a chant, thus freeing Reiji from Astaroth's possession.
In the anime, the Demon introduces himself as Astaroth, the King of Rot. After his quick defeat at the hands of Rin’s foster father, Astaroth manages to repossess the body of Reiji, leading to a second engagement, this time inside the church. Despite the use of his "major" form, the second battle also fails to go in his favour. After a brief skirmish with the Paladin, Rin and several other Exorcist that resided in the church, Astaroth is once again banished from Reiji Shiratori’s body.
