Arya was the greatest Archmage. She sacrificed her life, along with her friends, to save the world. One day, she reincarnated as a young noble girl.

"Wait, what the heck are magic circles? I have never seen one before .... Ohhh is this a magic lamp? How did they make it?"

"Eh? What the heck is a dragon rider?"

"I see, magic has greatly advanced in the last thousand years... Well, it doesn't matter. Life is about learning."
