There's a law in the outside world known as "Morphy's Law." That's how you write it, right...? Anyway! It means that bad things you worry about happening are probably going to happen. And thus did a completely unsurprising surprise strike the little witch!
Some little witches got very simple tasks: stuff like synthesizing the final solution to the material world, the Philosopher's Stone, -Little witch and the undying fire. (Mentioning Morphy law "Anything that can go wrong will go wrong." and philosopher stone:

Her sole reason for gracing Delphi with her presence was to marry Ike. -Vera Melanchony ( Delphi, is at the center of Greek Mythology.)

Paimon: Paimon's never heard of that one either...
Zhiqiong: Well, I'm not too sure myself, but given that Alice is an adventurer who has seen the entire world, so that must be some place she's been to... right?
Little Mao: She said that this cave is my "Rubicon"... Not that I know what that means...
