"Are you really going to another world?"
When Kira came out of Paradox's holding area, Mokuba looked at him with concern.
"Yeah. That guy was probably telling the truth," Kira said. "If the goal is to prevent both worlds from being destroyed, then our objectives should be the same."

Mokuba was still uneasy.
Kira smiled. "There's nothing to worry about. It's not like this is my first time. Haven't I been to other dimensions before?"
"But this time is different."
Mokuba shook his head.
"Did you forget what we talked about before? You may have gone to other dimensions, but fundamentally, you were still within our world.

Of course, that was only speculation. Paradox had said that history in that world had also undergone abnormal changes, perhaps becoming the source of the anomaly. So Kira
