Volga

Volga is a minor demon antagonist from the light novel, manga, and anime series The Testament of Sister New Devil (Shinmai Maō no Testament). In The Testament of Sister New Devil, Volga shares an identical personality with his older brother, Valga. Volga possesses extreme confidence in his demonic powers. He openly mocks his opponents and looks down on humans and the Hero clan, completely underestimating their tactical capabilities. Much like his brother, he firmly believes that raw power and physical supremacy solve everything. He lacks strategic depth, relying entirely on his reinforced muscular body and brute strength to overwhelm enemies rather than using complex magic or intellect. His arrogance ultimately leads to his immediate downfall. During his fight against Yuki Nonaka in the tournament arc, his inability to comprehend that an opponent could match or surpass his physical durability leaves him wide open, resulting in his instant defeat.
