The disaster of the powerless ESPer incident was starting to be fixed, slowly but steadily everyone started to go back to normal, including her. She just wanted to go home and take a shower, maybe watch a movie with her daughter.
When she arrived at home all of that crumbled, Anti Skills were gone from the building, some of them had stayed but they were too injured to keep anything safe. She rushed upstairs to see that her house was broken into. She was starting to feel dizzy from the shock, she was preparing herself for the worst, though Renko was sitting in the living room reading a book. There were bodies everywhere in the room, Renko was oblivious of them. Sumireko reached for her child and hugged her tight, how could it be? She was not an ESPer.
Then she heard a voice inside of her head, it wasn't one of those she already had inside, this was… herself, from another body. Renko was talking to her, the same curse she carried Renko had it too. Though the voice calmed her down at first. In fact Sumireko's mind inside of Renko made sure to keep all of those minds in control, Renko shared all the memories with them turning her into a very smart kid. But Sumireko gave up her ability to talk with Renko inside of her mind to be able to contain all the other consciousness inside of her head, the multitude was gagged inside of Renko's mind. Maybe she could be a magician if she wanted to, her own personality was powerless.
When the house was broken into Renko's mind realized the danger and unlocked the multitude, the enraged legion finished with the Skill outs in no time, there were more gang members who attacked than those inside of the room, most of them were vaporized. When the place was safe again Sumireko locked the multitude again and left Renko with no memory of what happened. The good part was that she was so spaced she went to read without realizing the corpses around the house. The Sumireko outside of her mind was feeling extremely fortunate for the turn of events.
Later on that same month Sakuya Izayoi arrived and told her the story of Accelerator, of how he died a hero and how humanity was going to be left defenseless. Then the true ESPer magician, the true messiah, Arjuna incarnated was going to take his place as protector. Now Sumireko with that knowledge understood that the ESPer was going to be herself inside of Renko's mind while the magician was to be Renko herself.
Sumireko now had a mission, to make sure her daughter wasn't as reckless as Accelerator, to make her avoid the same mistakes he did. The ways of buddhism were compatible with a secular life, such as her own, Renko could follow those principles without much problem.
