I'm Aika Fuwa the younger sister of Mahiro Fuwa that was committed suicide. I also the real Mage of Exodus.
I secretly dated Yoshino Takigawa. whom I deeply loved.
In the flashback during chapter 22 I stated that the only person who can go out with me is Yoshino and that I won't consider dating anyone else, even if Yoshino liked another person.
Mahiro is someone very important and special to me too, but not in a romantic way.
In chapter 37 it is revealed that I was the strongest magician of all.
I was the Magician of Zetsuen before Hanemura and was more powerful than Hakaze as I easily defeated Hakaze when the later was trying to prevent her from committing suicide.
