I watched the 8th episode a few hours ago and I found something weird.
We can see 2 people who look like a lot to Corpse God and Misami from Dead Mount Death Play (even with their way to speak ant act).
Maybe it's just a big coincidence or maybe it's me who's acting foolish because it was said and it's normal but I haven't found anyone speaking about it.
I think the 1st time when they appear is at 5:52.
