However, instead of making himself god he chooses to grant that to a girl in his life. The girl accepts all too readily for him out of his devotion to her and carries out the ritual as he intended. 

Supreme power is placed in the girl's hand and virtually anything could be bent to her will. Virtually anything except for the past. The powers the ritual bestowed granted one the firmest grasp on the present and the future but she could not change the events that had transpired. 

She obeys the young man's instructions and fulfills them to satisfaction at first but soon she finds him listless and contemplative. He would not share with her what occupied him so until one day he calls her over to his home.

She finds him dead on the floor with a manic grin on his face. He had killed himself and that could not be changed. She had failed again.

So she remakes the universe once more.

In truth the ritual did nothing to her. She had already been almighty before the boy thought to make her so. The boy himself was the newest simulation of a person she hoped to understand. She remade him and his world so many times now in so many different ways but her answer still eludes her.

"Why did he kill himself?"

She always made sure to give him genius no matter the circumstances and now matter how overjoyed, fearful or repentant the simulations felt about their new god, they would always end their lives in the same way - content and silent.

She could not truly bring her maker back so all she could do was to run her simulations over and over again until some day one of his simulacra finally lay bare his heart for her.
