Izana Kurokawa was the former 8th leader of Black Dragon. He is a young man of average height, with large purple eyes and a tan complexion.
Izana grew up in an orphanage. Despite desperately craving a family, he treats his subordinates like disposable tools and rules over them like a tyrant. He is dismissive of others and will make it clear that he looks down on them, regardless of friend or foe.
Due to his complex family history, Izana thought he was related to Shinichiro, Manjiro, and Emma. He loved and looked up to Shinichiro, and often sent him letters. Izana is jealous of his "younger half-brother" Manjiro because Shinichiro decided to pass on the Black Dragons to Manjiro, instead of Izana. After Shin died, there was nobody to help Izana stay on the right path. He had the possibility of being the kind, compassionate elder brother to Emma, but due to his years away, became ruthless and cruel. Not only has he become mentally unstable but, he strives for absolute power due to being helpless as a child.
Being alone made him susceptible to betrayal. He created Tenjiku and lead with a stern hand while being manipulated by his subordinate.
By his orders, Tetta Kisaki murdered his sister Emma.
Izana died by Kisaki's gun protecting his childhood friend Kakucho. Izana then proceeded to explain that he is not blood related to the Sanos at all—he was a child of Karen Kurokawa's ex-husband, who had Izana with a Filipino woman. He finally accepts that he isn't alone because of Kakucho, and accepts the defeat in his dying moments.
