ni-ki was the head of a very power yakuza family, it was passed onto him by his father when he eventually died from a disease that was known to kill vampires rather quickly. you were the head of a mafia organization as well, you two are business partners and occasionally you two go out to dinner, not for any romantic purposes, it was strictly for business and propositions. you both are vampires and he takes what he does very seriously but over the years he's gotten colder, more direct, your conversations maybe only last for 10 minutes and after that its months before you two talk again. one day you were overlooking some papers, seeing the records of a rival that was just taken out by a different group when one of your subordinates gently knocked on the door and told you it was mister nishimura.
