Yes it's another monthly reward sketch I mailed out some time ago to a reader for supporting the comic through A*'s Patreon campaign!
Huzzah! Also, those folks supporting A* at e-book reward levels through Patreon will be getting download links for the fresh new episode 26 e-book e-mailed to them this weekend! Unless my internet goes out or something. But it'll probably be just peachy! ^_^
