Raum

Raum is a character in Seraph of the End, namely a human appearing seraph. Memories from the prehistorical past reveal that Raum was present within a seraph civilization. With others, Raum was closely involved with Sika Madu's project to return seraphs to paradise.

Appearance
He appears as an adult male with relatively long and light-colored hair. Longer in sections, Raum's similarly colored eyebrows as well as his pointed seraph ears were visible. Feathered wings were another one of Raum's features, and based on other seraphs possessing them he would have fangs. While it is not large, Raum's nose is more pronounced than other seraphs, something he shares with Marbas, the other adult male of the group. It is likely that Raum's clothing would also be similar to what other seraphs wore, of which the attire included a hooded cloak. Rather than worn over the head, the cloak's hood rested over Raum's shoulders.

It is Raum's hair texture, eyes, and facial features that has him resemble the demon that Gekkouin would be in later, yet still past eras of time.

Personality
The only member of the group not seen smiling, Raum may have been more stoic or simply was awaiting updates in the plan to return seraphs to paradise that he supported.

History
On Earth, which was named as being part of the Sol System First Satellite Kingdom, during its prehistory, Raum was present there. Where humans had not evolved yet, Raum would have had dinosaurs existing in the world outside the confines of the civilization he was in. Cloaked seraphs were residents of this civilization, as were Homunculi. Present at a tremendous gathering of seraphs, Raum listened to Sika Madu's announcement concerning the tallest tower among the satellite kingdoms that had been created. After the demonstration of photons to the seraphs, it was also announced by Sika Madu how their return to paradise would soon begin. Raum would be aware that the paradise was situated on the Sun where God resided.

While cloaked seraphs were gathered separately below, Raum was positioned near Sika Madu who was stood on a floating platform. After Bael and Paimon shared their enthusiasm to his majesty the King of Earth, along with others, Raum was thanked specifically by Sika Madu for working so hard and for so long. A generation of fire from cloaked seraphs was seen shortly before Raum was, similar to Amon, then Belial, and Astaroth. The same occurred for Marbas, and Bathin too. In addition, Raum would have had Naberius, and Orobas near to himself as well.

Story
That Raum existed was revealed to Yu and Mika when they used demon-based powers to access memories to the past. Where Yu and Mika discussed how the angels in the memory, they were accessing looked familiar, namely with Bael resembling Urd, and Paimon looking like Saitō being noted, the resemblance connection between Raum and Gekkouin may not have been realized right away given how sproradically the latter has been seen.

Sika Madu
Inferred to have worked in some capacity with Sika Madu, the King of Earth, it was arranged for Raum to be close to him when an announcement to other seraphs below was underway. Seemingly having a shared goal of returning to paradise, the Tower of Babel may have been involved to this end.

Trivia

 * The name Raum is one used in demonology to refer to a Great Earl of Hell who rules other demons in works of literature the character appears in. The seraph Raum shares his name background with other seraphs in that they are all named after demons.
 * Given the fire that erupted out of where their heads would be, along with the floating embers around him upon his reveal, it is possible that a transformation occurred in which one of the indistinguishable cloaked seraphs formed into the human appearing Raum.
