While active on the internet, she discovered Mafuyu and is working hard to create a song that will save her. She has a typical Messiah complex, though she seems unaware of it. With Kanade's talent, she likely could have finished it already... She seems to be delaying it because her life's goal would disappear if she actually saved Mafuyu. She is unaware of this herself.
