The Siren Princess may belong to the Demon Species with powerful Magic Power, but she shouldn't be strong enough to defy common sense. It's hard to imagine her swimming alone all the way from the far sea to the near sea.
If it were only her, that would be understandable, but how did that rotting witch escape to land?
"I believe, in the near sea of the Southern Territory, to the inland rivers, there must be some secrets unknown to us. It could be a Transmission Array, or a special connected Space that allows the Mermaid Clan to cross ocean distances and arrive within the Kingdom's territorial waters."
The Fourteenth Princess analyzed.
"There was once communication with the Mermaid Clan in the Kingdom's history, although it was so long ago that there are basically only documentary records left. But if we can find records from that time, figure out which Prince this necklace belonged to, and then investigate his travel records..."
The Hero also became excited, nodding repeatedly.
