Rana herself didn't take long to understand the reason either after Rean explained how the demon beasts' portal was faring. "I see...now it makes sense why I'm a lot older then. With that, the only issue is why I'm here since I died down there."
Rean and Roan couldn't help but feel a little weird, talking with their little sister that was much older than them now. No, could one even say that she's their little sister? There weren't many memories to start with, so it was hard to think she would be the same as she was now had Sunkan Planet not exploded.
