It felt like Kendari had to start all over again when she returned to L-07. Those auras were far more troublesome than the one that was about to enter her body five years ago. She didn't understand why Kendari no longer wanted to feel those auras so she could understand and control them, but now she instead wanted to drop all of that aura and drag their souls to death.
Unfortunately, Kendari has not been able to get to that stage.
Controlling a human soul to the point of hypnotizing it is one thing she might do, but controlling a soul that has no body is a different matter. What's more, the spirits didn't even listen to anything she said; they kept fighting, and they kept getting angry with her.
"Why am I the only one they are after?!" she thought, frustrated with herself.
