Raws

I went searching for it, unfortunately they don't sell the raw chapters individually. You have to buy a volume which consists of many authors. (like the volume consists of just one chapter of different titles)

You can't buy all the raws digitally as the original chapters were published too long ago now, but the story is complete now and the 2 volumes are scheduled to be released 25/01/2021, so not too long to wait.
