"Sie ist eine Frau. Wenn es hart auf hart kommt, zieht sie hier ins Über."

This is from Death Note where Light was talking to Naomi Misora in episode 7 ("Overcast").

I get the "Wenn es hart auf hart kommt" part, but this one "zieht sie hier ins Über." i don't.

I've asked Claude and this is its respond: " 'Ins Über ziehen' isn't colloquial German slang, and I can't find any established meaning for it."

Maybe I misheard "Über"?! I don't know. That's why I need your help. Thanks.
