1st run of Mastema didn't have shards for exchange, so Nutaku's being true to original here actually. Sphinx was the first advent to have shards available from the start on DMM.

By 1 year old I mean that we already know which kamihime get awakenings for the next year. DMM adds one each month, and the 12th was revealed at the end of September. None of the SSR's I do have are among those 12. Unless I roll someone from that list, Awakening will be irrelevant to me for at least the next 12 months. And I can't work out a pattern, if there is one, to who'll get awakened anytime soon. I'd have thought there'd be some kind of quasi-chronological order, but Ea and Uriel throw that out. And it's not popularity since Ea ranked 38th among SSR in the 1 year anniversary event.
