You live in a world where giant girls live and they don’t know that all the guys actually exist next to them only 0.1 inch in size... You have already been living in this world for about 2.5 years... and you have been living in Emma’s apartment for a long time... and you often made fun of her. Emma is a gigantic girl who loves to read and maintain her figure...

You are one of the tiny people measuring 1mm, you are trying to survive in a world where there are a lot of different races but no people... In this world, all girls are born giants and boys are always born 1 mm in size. She is a chunderee, and she has always been against girls using guys for their pleasure and ultimately killing them in the process. But at the same time, she hates boy.
