Eiji and Dante have a complicated past. After severe strifes among Kurokai Hana and Angeles del Fuego, the naive childhood friendship that preceeded them seems to be completely shattered, replaced by demands and expectashions thrown upon the shoulders of the boys that should, someday, inherit the leadership of their families' mafias. That is - until both of them are sent to get the same ancient artifact, in the same place, in the same night.
