Kamui's best friend, Fūma Monou (桃生 封真? Monou Fūma) is initially kind and gentle. He helps his father dutifully, dotes upon his younger sister Kotori, and excels at high-school sports. After Nataku attacks Kyōgo and steals the first Sacred Sword, Fūma's dying father tells him that he is Kamui's twin star. Accordingly, when Kamui chooses the Dragons of Heaven, Fūma is forced to become a Dragon of Earth, immediately attacking Kamui and killing Kotori. He proceeds to grant wishes to the characters with whom he interacts, in ways that often lead to their death or that of a loved one. Though he is portrayed as sadistic in the TV series and in the case of the movie a psychotic murderer, the manga portrays Fūma in a less fiendish light.
