TL;DR:

Save her mind during the Heroic Route. Note: the relevant conversation happens before you cast the spell, but if you change her personality (by casting either Grapple or Confuse) the scene in the lake doesn't trigger.
Agree to turn her into a doll, then instead of fixing her right away, leave her inanimate and gain five levels.
Make her talk about her past while going on a date with her by choosing to talk either about the lake or the forest twice.
During her first conversation in the streets (when she teases you for being poor) cast Confusion on her at any time during the conversation. Sarah will lose her train of thought and the Protagonist will change the subject. Choose "Tell me about yourself" and she'll start ranting about how much she hates monsters.

Once you have done ANY of those four things, make sure she has 50 affection and is level 10 or above. You need to have reached floor 10 and at most floor 14 of the dungeon.

She'll then show up at the lake (east of the school) and ask the protagonist to tag with her to her home.
