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.

She also made you stay close to her since you were her lover and she usually wanted you to stay right were you belonged which was...on her chest. She was currently sitting on what used to be mountain while she towered over all of Japan.
