When Gaius said that, he took a big, deep breath once.
"Hmm... as Iris knows, I'm a reincarnator"
"Uhm. I know"
"So you know how reincarnators work?
"How does it work?... I don't know."
"Is that where you don't know very well?
"Right. I've never been very interested."
"Oh, I guess so."
Gaius shrugged his shoulders again.
Iris watched the trick with frustration.
"... just keep talking"
"Ok, ok. How it works, in short, if you live fifty years in this world, you are reincarnated into another world and live fifty years. I repeat," I'm coming back to this world again. "
"Oh. I've heard of it"
"So, how well does Illis know about the world over there?
Then the face of Ilis became another harrowing one.
"What does that mean?
Gaius said with a flat face.
"What, it doesn't mean a lot. I just thought... maybe Illis is a god in this world, but he's never been to that world, has he?
