SHOUT! Factory just announced on Twitter that Kyoryu Sentai Zyuranger will be getting a US DVD release, making it the first season of Super Sentai to be officially sold in the United States.
Zyuranger was the 16th season of the long running TV show Super Sentai, which is most notable for being adapted into the 1st season of Mighty Morphin Power Rangers. Unlike the Degrassi/Saved by the Bell clone that MMPR tried to be, Zyuranger was a high fantasy series involving 170 million year old warriors reviving from the dead to fight a witch that attacks modern day Japan.
