The show will air on April 2021, on MBS. Synopsis goes:
Koharu is a boring high school student who is lonesome in real life. Her only enjoyment is making plastic model kits. One day after returning from school, she purchases a model kit of a gun and a model kit named Alice. When she opened her eyes the night she assembled them, she discovered that she is inside a school in a remote location.

So the gist of this is that 12 girls will be in four teams of three, and each are lead by a leader called Lady Commander, the humanoid model kits. Lady Commanders can transform into model kit form and combine with the guns of the team members to unlock hidden abilities within the guns. The four teams will be pitted against each other for a survival game and the teams and their members:

This seems to be a totally original new IP from Bandai Spirits(the part of bandai that makes anything with a blue bandai logo slapped to it, pretty much model kits and high-end stuff like Figuarts, etc.) so it is not an adaptation of any kind. And none of the cast members seem to have any prior toku experience. I was expecting at least two but nope.
