Yue

Formerly known as Aletia Galdea Vesperitio Avatarl (アレーティア・ガルディエ・ウェスペリティリオ・アヴァタール, Arētia Garudie Wesuperitirio Avatāru), she was once a princess (later queen) of the vampire nation Avatarl, until she was imprisoned in the abyss after her uncle and vassals betrayed her and sealed her away. Due to being an Atavist with the unique skill to regenerate her body, she remained alive during her imprisonment, until she would be freed 300 years later by Hajime Nagumo and would be renamed "Yue" by him and would accompany him on his journey to return to his home. After moving to Japan, she would go by the name Yue Avatarl (ユエ・アヴァタール, Yue Avatāru), and would eventually became one of Hajime's wives.
