Seraph Eden

Seraph Eden is the first Hierarchy of Angels and is thus the leader of the entire angel army and is one of Goddess Ilias’ right-hands. She distrusts Promestein, a lower ranking with her own motives, and Black Alice, the 8th Monster Lord. She also hates being called the "Third Great Seraph", since Micaela and Lucifina became fallen seraphs and departed.

Biography
Eden is first mentioned during the siege of the Monster Lord’s Castle, having sent Archangel Ariel to assist. However, after the Archangel is defeated, Promestein calls Eden a failure. Luka can't help but wonder who Promestein is talking to, but she doesn't say.

After Promestein retreats, Eden urges Ilias to punish her, but Ilias decides to let it go.

While Luka rests in Enrika, Archangel Mariel reports that the invasion is going as planned, and Cupid reports of Promestein's Drain Lab. After Mariel accidentally labels Eden as the "Third Great Seraph" and leaves, Eden angrily declares that she is the First.

As Luka advances from Noah to Gold regions, Promestein calls Eden a failure when Throne Eggiel fails to provide enough cover for Amphisbaena to defeat Erubetie. Cupid overhears her talking "bad things" about Eden and leaves to report.

As Luka makes his way back to the Monster Lord's Castle from Gold, Promestein and Black Alice insult Eden, calling her "useless, incompetent, fool, obtuse, and third" and tell her that Ilias would be angry for her four failures. Eden tries to shout back, stating that Promestein and Black Alice also failed. Promestein then leaves, not wanting to gain a grudge from the seraph. Black Alice then wonders about inviting Ilias to their "tea party" before Cupid arrives to deliver a report and Black Alice takes her leave. Eden angrily scowls at her departed comrades.
