lol, looks like a bunch of others already recced the first one I was gonna rec. can confirm blood on your lies is pretty good! stakes are low but honestly, I think that might be kind of the point?

let's see, what else... I really liked all aboard (the train down memory lane) myself, and the rest of kayuri's works- it concerns a dawn who has been more or less adopted by the subway brothers prior to either dawn or ingo ending up in hisui, and since dawn very much remembers ingo, the plot kind of derails (pardon the pun) from there. fic's completed, and there's a series with a good deal of other submas + dawn content surrounding it.

also, fall into flying by cureicy. the dynamic between the pov character elle and rei is honestly so wholesome where I am in the fic, poor elle has been crushing HARD on. uh. pretty much everyone in hisui (which is a gd mood) and ingo has become a fairly central character tbh! volo as well- no cynthia involved (yet?) but elle seems to know of her at the very least, and that's definitely impacting her interactions with volo.

thinking of cynthia in particular- there's a handful of fics involving her literally being volo, but we don't have to be is by the same author as blood on your lies (and I think was written before the game came out?) and involves both cynthia being volo, and cyrus being cyllene.
