Vania

Vania (ヴァーニア) is a side character of the Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita series. She is a Leviathan demon and the air-headed, absent-minded younger sister of Fatla, and serves as Beelzebub's assistant in the Ministry of Agriculture in the Demon Kingdom. Though a natural air head and rather unrefined character, Vania proves to be a hard, energetic worker in spite of this quality, servicing Azusa and company diligently during the trip to the Demon Kingdom. She's also very loyal to Beelzebub as she and her sister accompanied her and a childish Azusa to the World Tree. Unlike her sister, she's not one for formalities or strict adherence to protocol, instead speaking to many guests rather casually and confidently, as well as indulging in the restaurants and facilities while on the mission to the World Tree.
