Had to rework Waggy's stupid pun a fair bit: in the original, she thinks that Akyuu is the daughter of a yakuza family, and one of the terms for a yakuza (chivalrous organization, ninkyou dandai) is close to "mermaid" (ningyou). I'm happy with what I got, though.

...In a perfect world, I would've rewritten the whole joke to have Waggy confuse "androgynous" with "amphibious".
