Anon wants to live a simple life but ends up in Equestria with the powers of an (Eldritch) God. Weeks after his arrival, Rarity buys him a diner/bar as a welcoming gift and business franchise where she can get her clients. Anon then works at his diner/bar and successfully lives a simple life, though things get more exciting each day for every pony he meets. Anon also occasionally uses his infinite powers to poke a little fun. Good slice of life stuff.

A human has arrived in Ponyville that the Apples dubbed, "Anonymous."
Twilight is worried he might be dangerous. They know nothing about him after all. However, the Apples still treat him like a common pet, until he begins mimicking speech.
