The Spirit and the Fire Floor

Shingi didn't expect the Spirit to notice what he did and that his eyes were the source.

"Wait, a second. Why are they red now?" [Spirit]

Not only could she tell that he did something with his eyes, but she also could see their proper color. Harbin told him that a few could, that wasn't of the same special Human Race as them, and he doubted the Spirit was one of them.

"The kinda reminds me of a friend of mine. She has an unusual color of eyes, but they aren't red." [Spirit]

"What color were they?" [Shingi]

If she knew someone when she was alive, it might prove helpful.

"Purple. But you haven't answered my question. What did you do to that person? You used a massive amount of Spirit Mana on its head… wait, don't tell me. Did you try to erase his memories?" [Spirit]
