"Gaia's True Magic is Unlocked" (Chapter 1)
For my game's "Easy Mode":
All the player has to do is bond with Mia to "S Rank".
When Mia inevitably dies due to a snake bite at the end of Ch. 1,
Gaia will unlock her "Light of Salvation".
Although, this isn't really an "Easy Mode", more like a Chapter Skip,
the awakening of Gaia's True Magic is what kicks off the final chapters of the game,
and puts her on the Final Boss's radar in the first place.
