Humanity Has Declined - Specials (2012)

Whilst sorting through a box of curious items left behind by the fairies, the heroine finds a spoon that lets her scoop flour out of her head. However, she ends up overusing it and winds up small.

Unable to get help from the grandpa, due to the way her miniature form transforms her speech patterns, the heroine searches for the fairies but comes up against a hungry bird.

After narrowly escaping the bird, the heroine meets an intelligent hamster named Yameta whose civilization is under threat from weasels.

The weasels' attack sends the heroine flying into a pond, where she is rescued by a handsome looking fairy.

The heroine gives up on trying to find a way to change back and enjoys her luxurious new life. However, whilst doing some cooking, she ends up using the spoon on herself again, becoming even smaller. She soon learns that the spoon converts her intelligent thoughts into flour, shrinking her to match her intelligence.

The fairies' realizing that she is shrinking, take her to her own home without realizing that they are the same person thinking that they can get some help. There they find more of the flour (which used to be her brains) with which they proceed to make cookies. Accidentally eating one before dying, the heroine realizes that it restored some of her intelligence and height. By keeping the fairies from eating the freshly made cookies, she ends up eating all of them and going back to normal.

A recap featuring fairies with new narration by Watashi.
