Akane Shinjou Shrunk by Mecha Anime Girls! chapter 3 by Ninten

Piloting your dimension-hopping, size-changing mech, you land in what appears to be a mostly normal looking world. A large, vast city expanded far into the horizon, but something about it felt almost... fake... or even artificial... You couldn't put your finger on why though.

Your mech's sensors indicate that it was relatively 15 cm (6 inches) tall in this dimension, making you about 2.5 centimeters tall (1 inch). How odd, but maybe being tiny would have its perks here. Anyone you came across would probably look like a giant to you.

You flew in through the window a normal looking apartment building, hoping to meet a local. But you were surprised to find that this cramped apartment was a complete pigsty... Filled up garbage bags completely covered the floor, and unwashed clothes were littered everywhere. Most of it was female underwear, so you assumed a girl lived here, but what kind of girl would live like this?

There were what looked to be models of different kaiju scattered about the cramped room. Models of giant monsters made of clay, plastic, and even wood. The girl who lived here seemed to like these giant monsters. Even though they were relatively small models, your new size in this world made you even smaller. You didn't know much about kaiju and tokusatsu stuff outside of the basics, but this girl must have been a huge fan.

Suddenly, you heard a noise! Was it the girl?
