Re: Miri's girls
Tanuki's luck power only extends to places of business (ie. his favorite bar, his favorite restaurant) and very rarely can he extend it to actual people - he would have to really want to. They could, or at least GET ANYTHING THEY'VE EVER WANTED AND GET AWAY WITH MURDER. Thankfully, neither seem like the murdering type.
She wouldn't have to because they're friends and he'd refuse it. He likes abusing his powers on strangers.
