Admirath

Admirath is a wind demon. He appears in Episode 8 of Season 2 (Burst) for a match against Kurumi Nonaka and shows her one of Basara's coat button, telling her that Basara's fate lies in her hands to reduce her confidence and prevent her from going all out. During their match, it was commented by Leohart & co. that though they were fighting fiercly, were not fighting with full strength. He still defeated Kurumi. When Admirath was about to kill off Kurumi, Zest interfered to protect Kurumi. Admirath is a cool, calm and collective demon, willing to show kindness when needed. But in reality, he is a deceitful and sadistic person that cons people into underestimating them. When in battle, Admirath becomes brutal and shows no mercy to his opponents.
