Aetheria Akasha - The leader of the Arbitrators, and the one with the most authority to lead to. Murakumo obeys her orders like all other Arbitrators. She finds her interesting to talk to. She was also personally selected by her to train the newcomers (Murakumo chose Akio though). They are both in good terms, and hence her being the leader she obeys her every command which benefits them both. Though she rarely talks, and give only necessary comments.

Master Biblia - She is acquainted with Biblia who has been away from heaven for a long time, and she casually call him "Biblia brother". Even though they aren't related by blood, she simply finds him interesting, and is very interested and joyed when he brought the new candidates to become Heavenly Arbitrators.
