He'll be added at a later date, yeah! The MC will, too, now that he's separated from the club lilac shenanigans.
In addition to those, every (bedonked) character will show up there to have a bit of fun, including some guest characters! For example, Isaac (a guest character of one of my friends) might have been removed from the overall plot, but he'll still show up at Club Lilac as a cameo.
(With the guest characters' owner's permission, of course)
