I just found out that this amazing manga got a limited 2-disc, 14-track soundtrack in 2016. Does anyone have it, preferably in FLAC?

Since an anime adaptation was just announced (https://twitter.com/pkjd818/status/1060813241146781696), I'm bumping this request for the manga OST. The only FLAC link I could find was this long-dead one from 4chan (https://boards.fireden.net/a/last/50/146614330/#q146626346).

Here's the title track by Igorrr, to give a taste: https://www.youtube.com/watch?v=yhQQ57N-9ys
