Belial

Belial (べりアル) is one of the two female seraphs seen in the Seraph of the End series. Existing in the prehistorical past, Belial lived within a seraph civilization. As with other humanoid appearing seraphs, Belial appeared committed to Sika Madu's project to return them to paradise.

Appearance
She appears as a young girl and is unique among the seraphs in this regard given that Bathin looks like an adult. Bathin has what are seraph features of pointed fangs, and even more notably her two large, feathered wings. Belial's medium length hair reaches down to her neck. A light-colored headband positions the back of her hair so as to keep her seraph pointed ears visible. The sides of Belial's hair reach her jawline, where bangs are across her forehead.

Belial wears cloak like attire where a hooded one would be around her. The light-colored hood is light-colored on the outside and dark within, and worn around Belial's shoulders. While her hair is much shorter, based on the seraphs' resemblance to vampires and demons that came into being in later ages, Belial closely matches Krul Tepes. Given this, Belial's hair color is probably a pinkish hue.

Personality
Appearing content, Belial apparently supported Sika Madu's campaign to return seraphs to paradise.

History
During Earth's prehistory, Belial was stationed on what was titled the Sol System First Satellite Kingdom. The native creatures at the time were dinosaurs where humans that she appears like had not evolved yet. Within a seraph civilization with cloaked members of her kind, Belial would have likely come into contact with Homunculi who existed in the city as well. During a gathering of seraphs, Belial may have heard Sika Madu's announcement that among the satellite kingdoms, a tower had been built taller than all others. After a display of photons by Sika Madu, the announcement detailed that they were return to paradise, a location on the Sun where a God awaited.

Unlike cloaked seraphs on the ground, Belial was physically close to Sika Madu from his raised viewpoint. After Bael and Paimon had spoken, Belial was a part of a group that were thanked for working so hard for so long. A raising of fire from the hood of a cloaked seraph coincided with Belial being shown, along with Amon, then Astaroth, and Marbas too. Belial would also have Bathin, with Naberius near her, as well as Raum, and Orobas too.

Concerning the project to return seraphs to paradise, Belial was beside Amon as he assured Sika Madu, they will follow him wherever he leads.

Story
Her existence learned about due to memory delving, Belial with other human appearing seraphs were seen by Yu and Mika. Since it was a memory of her being observed, Belial would likely have no idea that she was being viewed by individuals from future ages who were using demon-based powers to look into the past. It was mentioned by Yu and Mika how the angels in the memory including Belial looked familiar. Where Bael appearing like Urd, and Paimon looking like Saitō was addressed, Belial's resemblance to Krul was not specifically noted at the time.

Sika Madu
In close proximity to the King of Earth, Sika Madu, she may have been involved in the Tower of Babel that was to help return them to paradise.

Amon
As Belial resembles Krul, she is positioned next to Amon, the seraph who looks like Krul's brother Ashera Tepes.

Trivia

 * Belial is a name used by other characters in the real world, namely demon characters. Specifically, Belial is the name for the devil. As a seraph, Belial shares the fact that she has a demon name with others of her kind.
 * Where there was fire that appeared out of their heads, with the harmless embers around her upon Belial's introduction, it is possible that this indicated a transformation in which one of the cloaked seraphs formed into Belial.
