This is just a combined version of a set Nathan B commissioned last year, one panel at a time.

The story showing their adult male Miqo'te character getting transformed into a cookie-selling Girl Scout. And eventually growing accostumed to it and actually preferring being a cutie lil' cookie seller to an adventurer. And eventually bringing in a newcomer to join the gang.

Yeah, the Girlscoutification spreads that easily :y

You can see the separated panels here:
1, 2, 3, 4
