Astaroth

Astaroth (アスタロト) is one of the humanoid appearing seraphs revealed in the Seraph of the End series. Observed alive in the prehistorical past, Astaroth was within a seraph civilization. Along with others, Astaroth was involved with Sika Madu's project to return seraphs to a paradise.

Appearance
Appearing as an adolescent male, Astaroth has seraph traits such as pointed ears and large feathery wings. Although not seen, based on other seraphs possessing them, Astaroth would have fangs. For clothing, Astaroth has a cloak around him of which the hood is positioned over his shoulders.

Where his eyebrows are each the same dark color, the heterochromia of Astaroth's hair has it in two different colors. On his left, Astaroth's hair is light, then dark on his right. In both cases, the positioning of Astaroth's hair places it behind his ears. The centre, and right of his bangs is dark in coloration. Astaroth has less lighter colored hair overall, even not counting areas of the back that may be dark on his left side.

Distinct among the seraphs, his heterochromia is a trait Astaroth shares with a vampire, namely third progenitor Lest Karr who would come into existence in later eras. Where the group of ten humanoid seraphs do look similar to vampires and demons of future, yet still ancient past ages, it is likely not a coincidental resemblance. Given that, it may be the case that the right side of Astaroth's hair is a deep red in color, where on his left it is completely white.

Personality
Appearing happy, Astaroth was content to be a part of Sika Madu's plan to raise seraphs to paradise. For this, Astaroth shared the desire for them to be the first to reach the location.

History
Located on the Sol System First Satellite Kingdom, Earth, he was present there during prehistorical times. The native beings were dinosaurs where humans had not evolved yet, and within a seraph civilization Astaroth was with cloaked members of his kind, with Homunculi also present. At a gathering of seraphs, Astaroth would have been aware of Sika Madu announcing that the tallest tower among the satellite kingdoms had been formed. Once Sika Madu had displayed photons, it was declared that they were return to paradise. This was said to be on the Sun where God resided.

Unlike cloaked seraphs on the ground, Astaroth was physically close to Sika Madu where he was positioned on a floating screen. After Bael and Paimon had addressed his majesty the King of Earth, Astaroth was a member of the group that were thanked for working so hard for so long. A blast of fire from a cloaked seraph was seen shortly before Astaroth was, along with Amon, and Belial. Additionally, Marbas, then Bathin, with Naberius would be near him, as well as Raum, and Orobas too.

With Bael and Paimon having passed away, Astaroth joins the remaining group of angels in heading to their graves where Sika Madu was. He listens as Amon communicates to Sika Madu that the tower is ready with the power to return them to paradise.

Once Sika Madu appeared discouraged on the idea of returning given the many who had died, after Naberius spoke, Astaroth supported his view. Also in favor of them returning, Astaroth stated if it just for the sake of the fallen then Sika Madu should let them be the first ones to return to paradise.

"Yes. Let's return, Majesty. If just for the sake of the fallen. Let us be the first ones to return to paradise!"

- Expressing his keenness to Sika Madu on returning to paradise.

Astaroth is nearby to Amon as he hears from Sika Madu that he is right and they are to pass the word onto everyone as they are to return tomorrow.

Walking at the back of the group behind Amon some distance from the seraph city, Astaroth notices a scene above in Space. Where an gigantic homunculus was darkening the rings of light, Astaroth joined Amon to ask what was happening.

Story
Astaroth's existence was uncovered by Yu and Mika who viewed memories beginning in the ancient past. It was mentioned by Yu and Mika how the angels in the memory they were accessing looked familiar. Where Bael resembling Urd, and Paimon looking like Saitō was noted, Astaroth's resemblance to Lest Karr was not specifically mentioned at the time.

Sika Madu
Positioned close to the King of Earth, he had apparently worked with Sika Madu in a collective campaign to return all to paradise. Such projects may have included those connected to the Tower of Babel. Addressing him as Majesty, he addressed Sika Madu's concern on returning to paradise without others by stating they should do so for the sake of the fallen.

Amon
Near Amon, he also walks behind him when they are heading back to the seraph city.

Naberius
Once Naberius raised how they had worked hard to reach paradise, Astaroth spoke up in favor of returning too.

Bathin
A human appearing angel who is involved with Sika Madu's plan.

Raum
Another humanoid angel who is a part of the same group Astaroth is.

Trivia

 * Astaroth is a demon name in other works of literature, often a Great Duke of Hell. Like other seraphs, Astaroth has his name in common with them in that they are all named after demons.
 * On account of the fire that blew out of their heads, and the floating embers around him upon his reveal, it is possible that a transformation occurred where one of the indistinguishable cloaked seraphs formed into the human appearing Astaroth.
