>>75610571They do quite a lot as a duo! They have an entire lore for their characters established that they use for MVs and even a short anime, plus plenty of gaming/3D variety/idol leaning content, so it's pretty much a little bit of everything. If you want to get into them I'd say anything on their shared channel is a good place to start with, plus they have plenty of dedicated clipping channels (at least in jp, but there's a few english ones too).
I personally love their twitcasts together where they just relax and laze around, one of those is also where this clip came from:
