Coraline

Coraline (ボタンの魔女, botan no majo) is one of the very first Etherious, created by the black wizard Zeref, with the purpose of finally killing him. However, like the rest of Tartaros members, they developed a different idea than that of which Zeref had planned; which of course, involved the eradication of all magic, and bringing forth a world were demons ruled. As commonly known, this plan failed, leaving Coraline and the rest of the Tartaros Etherious in shambles. However, the fairly recent reformation of the guild, under Kraken Bones, has gained the opportunity for Coraline to bring out even more of her satanic fury.
