TSS: Tiny Hunt (Patreon)

The girl next door now has a name: Anais Sánchez!
As we see here, she's not entirely opposed to getting down and dirty when it comes to disposing of a tiny pest!
Since common tiny deaths like getting stepped on are covered in almost all shrinking insurance policies, it won't seem too off when these tinies' guardians get back. All she has to tell them is that their boys were up to no good, and were accidently squashed. Given her glowing reputation and sincere appearance, there's no doubt they'll buy her story.
