Ok for its time
It reminds me a lot of ボクガール - but less ecchi (also no SA so far), and more "by the numbers" in terms of gags and archetypes. For all my numerous issues with ボクガール, I found that series much more fun and interesting in terms of its character development and plot. In かしましs defense, it's from 2004-7, while ボクガール is from 2013, and was probly partially drawing from かしまし or other similar works (my speculation).
I do like that this doesn't take itself so seriously (while also not being so over the top), and I find the characters enjoyable enough. That said, the continued presence of the aliens in the main story is really disruptive, and doesn't add anything of value, imo.
Overall I enjoy it well enough both as a yuri and a trans story - tho it's rather simplistic on both fronts. I'm not in any rush to read volume 2, but I'll probably get to it someday.
