Adela’s approach actually works in most cases. People with a random Elyeo living among them aren’t too attached to her emotionally, so they are generally willing to let inductors take the Elyeo if threatened/ offered monetary compensation.
The problem here is that Hana isn’t just “some random neighbor with funny-looking ears”… She’s a dandelion child raised as their own.
PS. Check out the previous episode where Adela takes off her robe. I’ve made a couple of changes to make it clear that she’s NOT flashing her bewbs XD
