Someone that can please two girls with head pats is someone that can do anything.

Beware their power, for they are unstoppable.

And, somewhat unrelated, for some reason, seeing a wolf-girl with those tattoos just makes me think that maybe San got a little too frisky with her brothers…

There's the difficult way, of having two close friends to ask for their help.
And there's the illegal way. You need two little girls to start earning headpat exps. And you know how to get them.

Either way, it's not easy.
