I’m The Main Character’s Daughter
Thanks to her Personal Fragment, Stencil gained control of the System growing in her mind. Slowly, the lightning sparks destroyed the excess parts that she felt were undesirable, helping the rest fuse into one entity.
And since the lightning snakes unleashed by her Personal Fragment had taken control of it, forming what was akin to a nervous system in its body, the final fused System was an entity akin to a puppet, fully under her control.
'But, I cannot bring it out of my body. It would just dissipate.' She thought, eyes lighting up in surprise when she got an idea.
Stencil wasn't that young anymore. She was currently thirteen years old, more mature than when she was a kid who became Host to the Money-Making System. She had been through a lot during the two years she was a System Host, causing her to mature quickly.
