Fang Zheng remembered this part of the story very clearly.
Because Akemi Homura had told him that throughout her countless loops, several "plot points" never changed.
For example, QB tirelessly tried to sell Madoka on signing a contract, the Night of the Witches always appeared, and then there was Miki Saya's Blackening.
According to Akemi Homura, it was fine if Miki Saya never signed a contract to become a Magical Girl. But once she did, she would inevitably become twisted by Blackening and turn into a witch. Then she would certainly die!
There were no exceptions!!
To be honest, Akemi Homura had never had any fondness for Miki Saya. There were always people in this world who simply rubbed each other the wrong way. Even upon their first meeting, both could sense that they were completely incompatible. Akemi Homura and Miki Saya were like that too, so throughout countless loops, Akemi Homura often could not even be bothered to concern herself with Miki Saya. Whether she lived or died, what did it have to do with her?
Unfortunately, she could not do that.
Because Miki Saya was Madoka's friend. If she died, Madoka would be sad. Madoka might even choose to sign a contract with QB and become a Magical Girl in order to save her friend—this had happened before!
And the root cause of it all was that Miki Saya's childhood sweetheart had been hospitalized after an accident. His hand was ruined, leaving him unable to play the violin. So Miki Saya, filled with a spirit of self-sacrifice, signed a contract with QB and wished for her childhood sweetheart's hand to be healed.
Naturally, she did all of this because Miki Saya had a crush on her childhood sweetheart.
But how did that song go again?
