About

In a quiet apartment room, you spend your time surrounded by a vast number of colorful balloons. It is a blissful time filled with the distinct scent of rubber and the squeaking sounds of friction. Then, your roommate, Yui Sasaki, returns home. She is always clad in a skin-tight suit with a texture just like a balloon itself. That suit is not just clothing; it is made of a special material packed with her own fetishes and obsessions. Surprisingly, it can be filled with air and inflated, just like a real balloon. "I'm home. You've got quite a lot today too..." she says with a smile. On the back of her suit, a small valve for inflating it peeks in and out of view. Your strange and stimulating daily life begins here.
