This is an amazing story that I think falls into a similar camp as Deaths Daughter and Otome Heroine.

I personally think it's criminally underrated, also has the funniest epilogue I have ever read.

J-Novel Club is now doing DRM-Free manga so it's a good time to remind people that this spin-off is still unlicensed.

I recently read the WN and had a great time with it. The world building is good and I really enjoy the somewhat more complex and realistic characters/story. It's not simply "These are the good guys and those are the bad guys", but instead makes you think about the ideals, decisions and events. As much as I like my brain-off-feel-good series, it's novels like these that leave a lasting impression and I'd like to see this one getting an official English release.

To be fair, those two are relatively unknown series whereas Expelled From Paradise, IIRC, had a bit of advertising when it was released a few years ago, has mecha and more importantly, fanservice.
