She's the goddess responsible for the MC's reincarnation, tasking him with the unusual mission of killing the hero—a twist that sets the entire story in motion. Beyond just throwing him into this world, she gave him the freedom to pick his own skills during the process, which is pretty much the only mercy she offered him. Fans often note that this choice mechanic is what makes her different from your typical "summoning deity" character—she's not controlling every aspect of his new life, just the broad strokes and the impossible objective. Whether she has good intentions buried under that assignment or is just messing with him for divine entertainment remains one of the story's running questions.
