Huh... while Ichirin and Minamitsu are definitely confirmed to had been sealed underground, it's not a clear cut for the others.
The fact that Nazrin is acquainted with Orin and Chiyari (as seen in UDoALG) suggests that she was sealed underground too. A chapter in FDS implies that Kyōko was also sealed.
And Shō also seems to be included as well in the same vein as Kyōko – though this would be a contradiction, as it ZUN had confirmed earlier that Shō was sealed above ground? 🤨
