>>3621178The EPs were both autobiographical, sure, but Dead Beats focused more on how she sees her fanbase and Your Mori explores how her fanbase sees her
Then Off With Their Heads serves as an epilogue to the former and Cursed Night is a prologue to the latter.
And then Ibasho is just kinda doin it's own thing and doesn't fit into either of those arcs.
You can kinda see the beginning of a similar throughline with Cloudy Sheep and Spiral Tones, since they're both about crashing through boundaries into new horizons, so I'd expect other Holo-focused songs to build on that.
>>3621439She's not the type to really go out and make a song about one specific person or thing - but I could totally see a friendship-focused single about the bond between her and her genmates as a whole. Maybe when WoD wraps up?
