"A young boy born from a giant peach goes on a quest to fight some demons, guided by a Dog, a Monkey and a Pheasant."
DYK: Anime goes on to say that Momo is named after the Peach Boy in question and shares a similar likeness (being a young girl who likes Peaches) while the other three girls from the council each represent one of the animals; Hachiko the Dog, Hana the Monkey, Touri the Pheasant.
but then what about the other 4 new girls? well, my assumption is that they represent demons; Beni having the tiger-stripe stockings and wielding that spiked club, Rui apparently eating more than anyone else, and don't get me started on Ukan's *ahem* appetite.
What do you guys think of this? If only we could get Gaijin Goomba here to tell us a bit more.
