No, nothing that painless. [Well, it was for the assorted Wild Cards, but even then Naoki wouldn't call it a light decision. Or painless, on Minako's part; in comparison the various Inaba crews caught a huge break.]

Usually, how you get one is through the crap you've been repressing taking physical form, berating you for a while, and then trying to kill you if you don't accept it. I don't recommend it, and I recommend the other method I know of even less. So does the only person here who uses it.
