Bathin

Bathin (バティン)' is one of the human appearing seraphs revealed in the Seraph of the End series, and one of the only two female ones shown. Viewed via memories in the prehistorical past, Bathin was within a seraph civilization. Along with others, Bathin was a part of Sika Madu's project to return seraphs to a paradise.

Appearance
She was the only adult female out of a group of eleven seraphs. While Sika Madu had long braided hair, Bathin joined him in being the only seraph with overly long and light-colored hair which she wore down her back. Her seraph traits included pointed ears and large feathery wings. While not seen, since other seraphs had them it is probable that Bathin would also have fangs. Bathin's clothing was in keeping with other seraphs, namely she wore a hooded cloak of which the hood rested around her shoulders.

Her hair length and style to some extent, in addition to her being an adult female of a group of seraphs who greatly resemble vampires and demons of later ages by default results in Bathin resembling Raimeiki.

Personality
Appearing satisfied, Bathin was apparently dedicated to Sika Madu's plan to bring seraphs to paradise.

History
On the Sol System First Satellite Kingdom, Earth, she was present there during prehistorical times. The beings alive at the time were dinosaurs where humans had not evolved yet. In a seraph civilization Bathin lived among cloaked members of her kind and Homunculi as well. At a gathering of seraphs, Bathin would have been aware of Sika Madu's update that the tallest tower among the satellite kingdoms had been created. After Sika Madu had displayed photons to those gathered, it was detailed that their return to paradise would soon be underway. This paradise was declared to be on the Sun where God resided.

Where cloaked seraphs were gathered on the ground below, Bathin was stationed close to Sika Madu where he was stood atop a floating platform. Once Bael and Paimon had addressed his majesty the King of Earth, Bathin was thanked along with other members of a group for working so hard and for so long. A blast of fire from a cloaked seraph was seen shortly before Bathin was, the same with Amon, then Belial, also Astaroth, then Marbas, and Naberius too. Bathin would have additionally had Raum, and Orobas around her as well.

Story
Bathin was first seen by Yu and Mika who were accessing memories to the ancient past. While Yu and Mika discussed how the angels in the memory they were accessing looked familiar, with Bael resembling Urd, and Paimon looking like Saitō noted, Bathin would likely not have been recognized at all. By the present time Yu would have just heard of Kureto Hīragi's demon, Raimeiki yet has not seen her physically. Accordingly, Bathin is like Marbas in that a future resemblance to herself has not been seen by Yu or Mika.

Sika Madu
Whatever the method Sika Madu, the King of Earth, chose for selecting a group of seraphs close to him, Bathin was one of only two female members. From Sika Madu's praise, Bathin had seemingly worked with him in a collective campaign to return all to paradise. The Tower of Babel may have been one such project.

Trivia

 * Bathin is a name appearing in demonological based grimoires. In other works of literature he is a duke or otherwise prominent demon. Bathin the seraph shares her demon based name with other seraph members of her group.
 * From the fire that blew out of their heads, and the floating embers around her upon reveal, it is possible that a transformation occurred where one of the indistinguishable cloaked seraphs formed into the human appearing Bathin.
