Futsuugirl was introduced in the story of Futsuuman with ears of cat in 2010. She first appears in the popular Japanese restaurant JOYFULL (it is rather a cafeteria in which you can get unlimited cups of drink only for 400 yens) where Normalman always visits to be quiet.

Futsuugirl is the only one who knows where Futsuuman hides but apparently she is worried.. Ha Ha the story is coming soon

The history begins in Japan thus certain words are definitively Japanese, such as 'umeconbucha' which is the tea ( cha ) made of the dried plums ( ume ) and seaweed ( conbu ) extract.
Also Futsuugirl often says 'henin', which equivalent Japanese is 'NE.' Japanese uses this word often at every end of sentence:)
