Iwanaga may be a genius but sometimes intelligence alone is not enough for you to win a fight. Azalie is a magical genius as well so it’s not like Iwanaga has a big advantage there. Azalie is a better fighter at close range as well as long range so no matter how you slice it, Iwanaga’s doomed here. She would need a massive power up in order to keep this close and that’s likely not happening here. Azalie wins.
