That means you can earn an extra 1.3 or so shards per month through Advent Battles, on top of the 1 a week you can get from Weekly Missions. You can also get 2 per Union event as top-tier rewards. That's a total of 7.3 possible per month, or about 14 months to get a guaranteed SSR kamihime.
It's unclear whether even JP players have been able to get their first SSR kamihime from Draconic Shards yet...
