There was the saying "Any sufficiently advanced technology is indistinguishable from magic" so I don't care much about this part.It really is an abrupt end.
But I won't begrudge it, one way or another this always has been a silly goofy story.
But I really want for authors to stop with the "it was all aliens BS" when they want to end things, make it magic, make it something stupid... just leave aliens out of it.
At least all the girls are back.
I think he was saying the previous series, 1/6 Girls, ended due to magazine cancellation.It's joever drive girls
And if you read the author's afterword, it ended a bit abruptly because the magazine it was being published in was being cancelled.
