Quick Note on this page:

Negeru says, "Assassins and Mermaids" Originally it was supposed to be "mercenaries" but when Haruka (aka Yuki) was reading it over, she thought I had written "mermaids".....we laughed, we cried....and I changed it.

Yea, so the Aku-Teikoku produces Assassins and Mermaids....apparently.
