Rumia is cute, clever and honest but I doesn't still like her. I don't know why cant Rumia fight? She has fucking perfect power but she cant still fight. If she can't fight, then why did she enter a magical academy?
That is why I prefer Sistine. She is cute, tsundere and strong. Unlike Rumia She can fight.... Also, she is first heroine. if Lumia was first heroine, then I would drop the LN lol
