I found out the requirements for unlocking both Quests A83 and C15, for those that have not done so yet.

You need to complete Quest F65. Once you do that, both A83 and C15 should be available.

Here's my source: http://en.kancollewiki.net/wiki/Quests#December_27.2C_2017

For me, I did not have either quest available and after I did some looking around, I found the above link. I decided to give it a try, as I did not bother with F65 beyond unlocking the follow-on quests to do the new Quarterly after it showed up as I don't need all of the DevMats.

In any event, after completing F65, both A83 and C15 showed up in my queue to be completed... now I just need to get Naganami to K2...
