Looks like someone only has one useless head...

Forget about that already!

Anyway, pretty much every story where someone becomes immortal by eating mermaid flesh starts around the sea.

Even nonsense has its limits.

But even if it's fake, the idea of immortality would seem awful appealing to any anti-Moriya elements, right?

With that power, they could stand a chance of resisting even such ancient gods.

Seems kinda weak as an origin for the rumor, don't you think?

Well... What if someone's spreading it on purpose to find those malcontents?
