This was released on twitter as part of the 45th anniversary of Gundam as a franchise and to mark the 2-year anniversary of the original broadcast date of Witch From Mercury (October 2nd, 2022). Check out the Crunchyroll article for additional information. Synopsis of the first season from AniList:
A.S. (Ad Stella) 122
An era when a multitude of corporations have entered space and built a huge economic system. A lone girl from the remote planet Mercury transfers to the Asticassia School of Technology, run by the Beneritt Group which dominates the mobile suit industry.
Her name is Suletta Mercury. With a scarlet light burning in her pure heart, this girl walks step by step through a new world.
This show got a lot of hate at launch (as well as attempts at gatekeeping from the chuds bemoaning the influx of normies and “woke”), while I said screw that and enjoyed the excellent world building and storytelling. The pacing did fall apart in the second cour (to the point where I was convinced there was going to be another full season) but I still enjoyed it overall. Hard to believe it’s been two years already.
I liked it and am glad for the diversity it introduced.
