Today is a TRPG day! It's been a looong time since she played one if we don't count these detective style TRPGs on the main Hololive channel. I remember her collabing with all three of these members before, but I don't know if she has played TRPGs with all of them in the past. Pretty sure that the first one (Ngo) was on that Himehina stream with her and Miko last year, the second one (Mememe) was part of her FF14 apartment tour and the last one is part of one of her regular TRPG groups.
