She is an author, both of video games and of books. She made a game with what many have complained are some very cheap sprite knock-offs of other games, and in the book she later made based on the game, this was alluded to when the first main character encountered by the female protagonist (the one depicted in blue) is described as looking exactly like Cloud Strife from Final Fantasy VII.

When I went to wish her a happy birthday, I wanted to do it in a cheerful way, so I began drawing the characters, but then realized the arrangement would’ve been weird without context, so I also drew Sephiroth, another character in Final Fantasy and the villain who Cloud Strife canonically fights, to make it equally perceivable as a Final Fantasy drawing as it would be a drawing of her book/game, even though Sephiroth’s existence is only jokingly implied in the book/game.

And then I added a bit of dialogue because that’s my thing when I draw stuff like that. The text reads “do you have a moment to talk about our lord and savior Jenova”, Jenova being the name of the alien cloned to create Sephiroth in Final Fantasy, thus I was remaking a common pun in the fandom. It was the only thing I could think of that would both fit the situation in the drawing, be enjoyed by the author who also happens to be into spiritual studies (which is a part of how I came to enjoy the author), and need the least amount of explaining to anyone who came across the chalk drawing.
