>I wish to be isekaied into a fantasy world as a slimegirl adventurer with, in true isekai fashion, a single overpowered ability, preferably related to something like (giantess) growth, defense/regeneration, or lust.

You are now a slime girl, roughly the size and volume of a normal human. The fluid you are made of is a powerful aphrodisiac. Anyone two smells or especially tastes it will become extremely aroused. Your fluid is also highly addictive.

The catch is that the main villain of your world is the Demon Lord of Ice, and since you are a liquid you happen to be extremely vulnerable to his powerful ice magic. If he defeats you he will use your fluids to create potions of mind control and begin enslaving the entire free world. If you are not careful you might end up being the key to his plans of world domination.

>I wish I was a kind and cheerful person.
