You wake up on what appears to be some kind of white landscape that seems to stretch on for as far as the eye can see. This landscape also appears to be...moving.

This is because this landscape was actually the chest of your girlfriend Rumi Usagiyama who was also known as the Pro Hero Mirko.

See, just a few weeks ago, Rumi was accidentally hit by a size ray made by U.A student by Mei Hatsume which grew her to around 100 miles tall. In the following days, Rumi single handledly ended the entire League of Villains without breaking a sweat (you're not even sure if she even noticed due to how massive she was), leading her to become the greatest hero in Japan and possibly the entire world: Giga Mirko.

During the next six months, Rumi made a lot of changes to Japan. She changed Japan's name to the United States of Mirko, normal sized people were referred to as mites and several women were grown to 6000ft tall by the size ray Rumi had forcefully taken from Mei so that these women would be used as Rumi's slaves and maids.

She even had a massive house that was scaled to fit her massive size which towers over all of Japan.

She even still had Mei's size ray so she could shrink or grow anything she wanted.

And you?

Well...she made you stay close to her since you were her lover and in her eyes you were the only person she actually cared about. She was currently sleeping on her massive bed while you were laying down on her chest.
