Brian is a character from the expanded universe who hasn't been introduced in this webcomic. For consistency's sake, I have included some bits of his presence that are part of this story in a tangential way. His boxes are alongside Kat's, Hotaru's, and Shannon's in the attic for context. He's explained a bit more on my secret Patreon that I haven't told anybody about yet because I wanted to fill it up a bit more before launch. He'll be along eventually... as I release more titles in the BLU. For now, he's just kind of in the background as a name on a box.
