Oh maaaaan I really like this, loving all the hints of whatever this world is, like the necromancy and Tsukishima's dreams needing to be reported. But even with the edges of big world building, there's still all the comforting familiar interactions, especially Tsukki and Yamaguchi but also the stuff with Kags and Hinata, and 'Asahi panicking about something.' I'm so interested about whatever else you have in your head for this universe.
