This is Rakshasa, a nine-tailed fox who likes to gamble and for work, arguably a mercenary.
Being blind, he relies heavily on his sense of smell and a kind of sixth sense that is given to him by his third eye (the one that is in a red stain on his forehead), combined these two senses give him the ability to identify who tell the truth or who is lying. And if you find someone who lies... he is torturedly burned by his blue flames.
