Leia

Leia (レイア, Reia) is a one of the Thirteen Demon Lords and a demon created by Zeref about 400 years ago. She was released from her book by a member of Tartarus and escaped from their clutches since "the people are too annoying and loud". Leia wandered around Earthland for 400 years until she met Rizevim who was on an errand at that time. He invited her to move over to Occultus which she agreed since she became curious about the place. At some point, Leia was granted the position of one of the Thirteen Demon Lords. Her title is Gravity Ruler (重力 定規, Jūryoku Jōgi).
