The ghost Sonia used a sword made by spiritual power. I don't know what that is.
There's magic, and there's Aura. And there's another thing called spiritual power?
"What is spiritual power?" I asked Sonia.
"I don't know. I called it that way since it's different from Aura and magic. And I can only use it fairly recently. Whatever the case, with this, I can fight other ghosts. Let me handle the ghost," she said.
"Did the ghosts appear before, or do they only appear this time when I came here?" I asked her again.
"They only appear now. If they appeared before, I won't come when you called me since I would be fighting them."
"One more thing. They tamed ghosts. Does it mean that ghosts can actually fight living beings?" I asked Sonia again.
If ghosts can really fight living beings, she would be a great help. But she's already a big help as it is. Being our messenger. There's no one else like her.
