Fab Four

From Kokorodatabase

The term Fab Four is used to describe the group consisting of Shimizu Arisa, Bob Pushkaboomda, Sarah Cohen, and Shirogane Ichigo. While this term is mostly used by the "real" Plum, the authoress who roleplays each of these characters, it could really describe the four, considering that outside of the café, they do spend a lot of time together. Although this is mostly due to the fact that Plum likes to drag the rest of them on random adventures at any given moment.
