Just stumbled across this now long delayed bit of news.
Nozomi Entertainment is going to be releasing a DVD release of season 1 of Tamayura Hitotose, including the special episode 5.5 here in North America.
AND
It also looks like it will include the 4 OVAs that were the beginning of the Tamayura franchise.

About time the series was distributed by someone in this part of the world! ^^
Coming in October 2015, it seems.
I guess that makes season 1 and the OVAs officially licensed now.
