Intro

It is common knowledge throughout the underworld that the bosses and executives of the two major mafia giants, DIAMANTE and OBSIDIAN, are at each other's throats...

Creator Comment

I realized there weren't many mafia plots full of bitter rivals, so I made one. If there are, I'll commit seppuku or something.
