It's probably a Holo TTRPG or DnD thing. Imagine a Critical Role collab lol. But I remember there were two recent big indies that graduated, and I distinctly recall one of them saying they were going on a quest, even highlighting it in red. So now I'm wondering.. maybe a hint? It fits at least.
It's been over a year since her last stream and I don't know JP, only using translate, but her last post on X she said she was taking a break? Not sure if she mentioned more information on it in her last stream. Thanks!

TLDR:
Everyone is amazing in EN, she did her best in BD especially, but feels she has to work super hard to keep up. She has no singing or dancing experience vs almost everyone, just a gamer/streamer. She wanted to try to stand beside the others in singing as a Hololive.
She wanted to tell everyone with Ghost that "Hey, I like singing too. I like performing too. I want to make music too. I am here too." The lyrics (Can anyone hear and see me? I'm right here, I'm singing until my voice gives out, I'm like a ghost singing into the dark) sorta feeling have special and personal meaning for her because of this.
She no longer feels like she's singing to catch up, she's singing because she wants to, she wants everyone to hear her voice and feel her feelings.

At this point aiobahn has been interacting alot with Advent in their feed since start of the year (not to mention the song with Fuwamoco last year). I wouldn't be surprised if they release an Advent song.
Such a busy gen even before the EN concert.

True ASMR meaning they recorded these with the expensive ASMR mics in a room.
