ブレンダン

A hero who came from another world in search of a peaceful paradise.
Her original world was full of lies and violence, and
the only peaceful place was the sea, where no people lived.

Like Prester, she seems to be able to understand the language of fish, and
she learned the language of this world from the fish.

Her partner is a giant snake dragon named Jasconius.
