A tall, pale young woman, September Decima is the seventeenth child of the fallen god Judge and his daemoness consort Runya. With red hair and purple eyes, she stands out in a crowd. Taking more after her mother than father, September is out for herself, first and foremost. With Timedeath and the appearance of counterparts from other worlds, September consumed her other self from Daeluin, and gained her memories.

A talented archer, September imbues her arrows with deadly spells. She also has visions occasionally, though these are uncontrolled. A gift from her other self that she is still learning to hone, she can also draw scenes past and present. September also occasionally sees the future in her drawings, though she has no control over this ability.

However, when her brother Mendean fell, September was murdered by Luzia in cold blood.
