Age: died at 22 years old.
Non-existent in Kurumada's original manga, and said to be neither Specter nor Saint, Owl Partita (オウルのパルティータ, Ouru no Parutīta?) was in life, a young woman, servant of Pandora's family, wife of the Specter Mephistopheles Yōma and mother of Pegasus Tenma. She was abandoned by Yōma during Tenma's early childhood. The memory of holding her rough hand lies deep within Tenma's heart. She was killed by the Skeleton soldiers sent by Pandora. She is revealed by Yōma to have been revived by Hades, and gravely wounds Pandora in revenge for her murder. Partita is then introduced to Tenma wearing her armor, which resembled a Surplice, as guardian of the Uranus Demon Temple (天王星の魔宮, Tennō-sei no Makyū?). She forces a reluctant Tenma to engage her in battle. Partita projects memories of her and Tenma's past in her sons' mind to further weaken his will, and vows to kill the Saint, as she considers him the greatest sinner against heavens, and states she needs the soul of her son to help her and her husband in the uprising of humans against the gods of Olympus, and breed a new mankind. Then she is surprised by Pandora, who survived her assault. Partita attacks Pandora with a powerful Cosmo burst, leaving her in a critical state. She then turns against her son, with a second attack, which is absorbed by Tenma to protect Pandora. Then, astonished, Partita witnesses her son's Pegasus Cloth acquire a golden hue. Her Surplice is partially shattered by Tenma, and in turn she manages to mostly destroy the revitalized Pegasus Cloth. She extracts Tenma's soul, which is then retrieved by the Saint. The soul then causes the Pegasus Cloth to resurrect as the Pegasus God Cloth. She and Tenma clash in a final effort, and she is mortally wounded. Before dying, she reminisces about her past in Olympus as the messenger of Athena, before both reincarnated as humans, and the night Yōma tried to kidnap Tenma. Truth is finally revealed that after her revival, she disguised herself as Hades' guardian to spur Tenma's full potential and bestow the Pegasus God Cloth on him through battle, thus fulfilling the promise she made as Athena's emissary.
