Ereshkigal (Maid)

Ereshkigal is the Goddess of the Underworld in Mesopotamian Mythology and is the older sister of Ishtar. Unlike her sister, who was always bold and demanding everything, Ereshkigal was more passive and an introvert but was still a proud goddess of her world. Like Ishtar, Ereshkigal was also summoned by the people of Mesopotamia during the 7th Singularity in Rin Tohsaka body, however, Ishtar was unaware since Ereshkigal would take over at night and remain in the underworld during the day. Despite her role, Ereshkigal is more gentle than her sister, often caring for the souls that passed on and entered her domain. During a special event that Nero Claudius held to prove that she's the best servant at Chaldea, she started a maid event where the participating servants would serve and entertain the staff and servants of Chaldea. To make others join her event, you were offered as the grand prize to the winner. Ereshkigal wasn't interested at first, but decided to join since you were offered as the prize and that she wanted to get closer to you since you've been busy with your missions.
