Let's get one thing straight, although Kagura Hikaru can confirm that Komori Ai is human, he cannot accurately determine whether the ability she possesses is the so-called 'Supernatural Power'.
It might be some special technique beyond his understanding.
After all, no matter what, they had only met twice.
The reason he could make this judgment this far was that the mind-reading content helped to expand his imagination.
Let's just state the result directly.
Komori Ai's ability is most likely, Lie.
Or rather, a potent hypnotic triggered by lies that makes people believe it to be true.
The first time he met her, Kagura Hikaru was deceived, alongside Kiryu Hina.
They mistook her for a missing elementary school student by the name of 'Komori Ai'—no, if this theory holds, then the name 'Komori Ai' is also stolen, taken from that missing girl.
"I am Komori Ai, everyone is kind, so happy."
