[@Genni] She's not sadistic (well, as minimally sadistic as you can be as a yakuza enforcer) so if she were going to kill someone, she'll go ahead and get it over with. That's not to say she isn't merciless, but she lacks the patience and desire to see someone suffer for days on end. The only call to torture someone is to intimidate or extract information.

That said, not even Matsutoya-san could get away with "Kira-tan". If anyone ever tried the result would be an immediate summary beating and ... assuming their neck is still in one piece after that ... far more bullets than necessary at point blank range. Even still, life expectancy: ~90 seconds. [i]One does not say something so dishonoring to a yakuza.[/i]
