Finished scanning the Episode 0 manga! This is set 10 years before the start of PSO2, and covers the events prior to Melfonseana's death.
For this, I'm trying something a little different than previous posts--instead of text links, the Imgur embeds for each chapter are beneath the cut. You may need to 'authorize' Imgur embeds to see them. LMK if this works better (or worse) for you.
Looking for more scans? The master post is here!
