ナギ・ス・ラガール

Nagi su Ragarl is one of Four Lords of Zeth, and the only daughter of the great magician Chenezale do Ragarl. Nagi was born between the magician Ragarl and Athmaze, mother of Shizuka Masou, making Nagi a half-sister to her.

She didn't have a normal childhood, the only things she had in her life were the study of magic and her Father. She holds a grudge against her half sister, Shizuka Masou, since for her entire life she was just raised by her father to beat Shizuka. This grudge has driven her half mad and she has made magical enhancements to her body in order to defeat her half sister, which have made her a half monster. Due to the training and all the twisted and wretched methods she's used over her life to strengthen her magical power, Nagi is one of the world's most powerful humans and mages, being easily stronger than her half-sister. However, the experiences and life she's gone through has led her to go completely insane to the point she lacks common sense or any self-care.
