arbas(CV:yūTaichi[5]？ )

The second heroine

Main magic skills: chapter of protection, chapter of hunting.

The real name is unknown. Moon Witch, granddaughter of Corna, member of Zero Magic Troupe. The first episode of novels and animations appeared. Because Corna was killed by human beings, he wanted a mercenary's head to improve his magic and get back at human beings. He is good at healing magic and divination, and once divined the position of zero detention. Finally, he became the chief magic messenger of Venhaas. I like to call the mercenary "Uncle", and I like to learn magic from scratch to maintain the magical boundary of the kingdom of Venias. Because of the assassination of the kingdom, the suspicion of 13' s kidnapping of the prince and the yearning for grandma Corna, Shanari used it to launch a holy war against the church, which led to zero's mother killing 13, and she regretted her childish behavior. After the death of 13th, it inherited the magic of 13th, and launched a guardian phalanx in the whole kingdom of Venhaas, making the kingdom of Venhaas a pure land in the northern region where demons were rampant.
