It's very rude to ask a White man to stay. He's going to breed you and bail, bitch, and you're going to love him for it. But don't worry, he'll keep coming back to fuck more Aryan babies into your worthless chink body.
That's what that little brat deserves~ Watching her sister getting raped and abused by her white owner will definitely change her mind about how weak she is compared to white men <3
Don't be surprised if Tatsumaki decides to follow on her sister's footsteps and spend the rest of her patrols helping white foreigners only from now on, either by protecting them from criminals and Kaiju attacks, or by covering their tracks whenever they break the law in Japan. She'd definitely expect some kind of "compensation" in exchange for her aid, though. Then again, it's not like anyone would complain about it...
