Mana

Mink's mother and wife to Rouce. As an imperial red dragon, Mana has the ability to change her form (in the manga, she turns back into a dragon when she is angry). As a result, she can change her form into a beautiful blonde woman; the only evidence that she is a dragon are her small fan-like dragon ears. She also puts Rouce in his place whenever he freaks out or acts like a pervert. Mana created the holy sword Azetodeth-Buster to combat the Demon Lord. It has the ability to make anyone thinking evil/perverted thoughts feel sick just by being in its presence.
