C.C. Shrunk by Mecha Anime Girls! chapter 3 by Ninten

Piloting your dimension-hopping, size-changing mech, you land in what appears to be a normal looking world. Though you seem to be much, much smaller in this world compared to your own...

You see a massive, rich looking academy and fly in through an open window. The smell of what seems like pizza wafts towards you. You felt lucky that you ended up in a dimension that has pizza. And now that you were so tiny, you could enjoy it at giant size...

Flying over to the stack pizza boxes, there were at least four or five on the table. And as for the person who presumably ordered them...

A giant, beautiful, lime-green haired girl towered over you and your shrunken mech. She had incredible curves, and her eyes had a special glint about them... The giantess was in a school uniform, but her blouse wasn't fully buttoned up, exposing her cleavage.

You had to think quickly, do you sneak in for the giant pizza, or was the beautiful giantess too much to resist?
